FAQ’s

Naiad is committed to answering any questions you might have regarding your irrigation systems and our services. Can’t find the answer to your question? Contact us and ask one of our experts. Below are the most frequently asked questions from our customers.

  • Memberships
  • Spring Activation
  • Winterization
  • Cross Connection Testing
  • Installation
  • Lawn Care
  • Snow Removal

Can I pay for a full year?

Yes! Annual Memberships are available for Spring Activations, Cross Connection Testing and Winterizations. Whether you are looking for monthly or yearly payments, both options are available and will auto-renew.

Does my membership cancel after 1 year?

Memberships are designed to be a “set it and forget it” solution. This means that all of our memberships (both monthly and annual) will automatically renew unless either party notifies the other within 30 days of the annual renewal date.

When do I get charged?

If this is your first time signing up for a membership, the initial payment will be made once your service is completed that year. Monthly payments for Monthly memberships begin as follows:

  • Spring Activations – May 1st or the next month after service is completed if done after May 1st
  • Cross Connections – May 1st or the following month after service is completed if done after May 1st
  • Winterizations – October 1st

If your service is booked after the initial payment is due (e.g., October 8th – though that’s later than we recommend), the monthly payment will still begin on October 1st. The initial payment will be charged on October 8th after completing the service.

How do I schedule my services for next year?

Your membership services for the next season will be automatically scheduled by us before the season starts. When this happens, you will receive an automatic appointment confirmation for the date each service has been scheduled; if any changes need to be made, please contact us, and we can adjust accordingly. Note that scheduling is based on regular operating hours and availability.

Why can’t I use a debit card for pre-authorized payments?

Currently, our software is unable to process pre-authorized or visa debit payments. We do, however, accept Visa, Mastercard and American Express.

If I move, can I transfer my membership?

If your new property has an irrigation system or device applicable to the membership, we can transfer that membership to the new property. (Note that adjustments may apply as pricing for Activation and Winterization Memberships are based on system size).

What happens if I cancel before my service(s)

We understand that life can happen, sold your home? Not using the irrigation system anymore? Not a problem, if you need to cancel your membership we are more than happy to do so and provide a full refund for any payments made up to that point.

Why do I need a membership for each cross-connection control device?

We require an individual membership for each device to ensure that all devices are tracked and serviced properly.

Can I just combine all of my memberships into one membership?

At Naiad, we realize that not everyone wishes to have their system activation done by us or may not have a cross-connection device to be tested. With this being the case, we have decided that by keeping all our memberships individual, our clients can select strictly which memberships they want for their particular needs. Rest assured that once your memberships are in place, you will only see one consolidated payment per month (or year) regardless of your many memberships.

How do you turn on underground sprinklers?

There are many steps to activate a sprinkler system properly. You can refer to these detailed instructions from the Naiad Blog.

How do you manually activate a sprinkler valve?

Find the valve’s solenoid. It’s a plastic cylinder with wires attached to the top of the control valve. Slowly turn it to the “on” position until the water can be heard flowing through the valve. Turn the solenoid to the “off” position to shut it off. Only twist the solenoid by hand, and be careful not to over-tighten it.

Note: If you turn the solenoid too many times, it may become unthreaded from the valve.  If that happens, shutting off the water to the sprinkler system and threading it back in is a good idea. Be careful, as these are plastic fittings and can be easily cross-threaded.

If you’re wondering, you must have noticed your solenoid’s “on” and “off” markings. These are misleading because they refer to whether or not the valve is manually opened, bypassing the timer’s control.

Technicians often do this to test or winterize a system without entering a client’s home to access the timer.

For normal, automated use, the solenoid should be “off.” Don’t worry; if it’s wired in and working correctly, it’ll be ready to open the valve automatically when the timer says so.

Tighten the solenoids by hand, and be firm but careful. Overtightening can cause their plastic body to warp.

How do I know if my underground sprinkler system is working?

  1. Find your water meter and ensure it is not turning.
  2. Go to your irrigation timer, turn on a zone, and then look at your water meter. If the water meter turns, you know water is going to that zone.  You can repeat for all zones to ensure they are all working.
  3. After you have confirmed that the irrigation system is working electronically via the timer, you can then turn on each zone and check to ensure the zone is functioning correctly.

When should I turn on my sprinkler system in the spring?

It all depends on the weather. In Calgary, we typically start turning on sprinkler systems on the first Monday in May. We tell clients they should have their irrigation system up and running by the Victoria Day Long Weekend.

How do I winterize my underground sprinklers?

  1. Shut off the water supply to your sprinkler system. The shut-off valve for the sprinkler system is usually just downstream of the water meter.
  2. Hook up a compressor of at least 70 CFM (cubic feet per minute) to your sprinkler system’s blowout port (typically a garden tap) and expel most of the water from the irrigation lines and sprinklers. Do not exceed 80 PSI.
  3. As the system winterizes, walk around the property, looking and listening for possible leaks. Air acts differently than water, and sometimes you may be able to spot or hear a leak that you were not aware of.
  4. After winterizing the system, shut off the second isolation valve outside if you have one and leave the blowout port open.
  5. If you have a drain inside the house on the main water line for the irrigation system, please open it and leave it open for the winter. Do not be alarmed if some water comes out; that’s normal. It is best to have a pail to collect the water. After an hour, it should stop dripping. If water keeps dripping, your shut-off valve for the irrigation mainline is not working correctly.
  6. Allow your system to “dry run” its irrigation cycles over the following week before turning off your irrigation timer. It is best to have the solenoids (the electrical switches that control your system’s secondary valves) activated a few times after winterizing the system.

Do you have to winterize an underground sprinkler system?

Yes, you do.  Most of the water must be expelled from the irrigation system every fall. Otherwise, it will freeze, expand, and damage your underground irrigation system in the winter.

What does winterizing sprinklers mean?

When water freezes, it expands. Thus, most of the water must be expelled from the irrigation system before the water can freeze. This is called an irrigation system blowout because a compressor blows out most of the water. Once most of the water has been removed from the sprinkler system, it is ready for winter. A few clients ask if we put antifreeze in the lines.  We do not.

When should I winterize my underground sprinklers?

A sprinkler system should be winterized before overnight temperatures fall below zero degrees Celsius.  For us here in Alberta, we recommend winterizing your irrigation system before the end of September.  We have had a few years when the overnight lows have been cold enough to damage the main waterline for the irrigation system as early as September 28th.  Ultimately, you can run it later into the season, but there is always the risk that a cold overnight low could damage your irrigation system.  The bit of pipe that goes from the house to the valve box is most at risk. That bit of pipe is exposed to the elements and can freeze faster than the pipes or sprinklers in the ground.

What if the overnight low is cold, and my irrigation system has yet to be winterized?

What we recommend is the following:

  1. Shut off the water to the sprinkler system.
  2. Find where the mainline comes out of the house and open any garden taps or remove any plugs attached to the main water line of the underground sprinkler system to allow the water to drain out.
  3. If you have a ball valve on your mainline, leave it open. (If Naiad Irrigation Systems Ltd. installed your system, there is almost definitely a ball valve.)  Trapping any water in the ball valve by shutting it off will cause it to burst as the temperature drops and the water freezes.
  4. Open your valve box, open any bleed screws, and loosen any solenoids (turn counterclockwise). If you cannot find the valve box or identify these parts, just run all the zones manually using your sprinkler timer. This will accomplish the same thing.  By turning on the zones and opening the hose bib attached to the mainline, gravity will allow the mainline to drain, protecting the exposed bit of pipe.
  5. We have seen some clients insulate the valve box by putting something over it, such as a thick blanket or some pink insulation. That may help keep the warm air in the valve box.
  6. Lastly, if there is a lot of snow in the forecast, please mark where the valve boxes are for your irrigation system. That will help your irrigation professional find the valve box under the snow.

Is all of the water removed from the sprinkler system during winterization?

No, but the majority of it is.  There is always a little left over.  The point of winterization is to remove the majority of it, and the remainder will not be enough to damage the underground sprinkler system.

Also, sprinklers are not watertight.  As easily as water leaves the nozzle when the sprinkler system is on, water will return through it, too, via snowpack melt and/or rain.  Water entering your system gradually throughout the winter is unlikely to cause damage.

Lastly, rotor-style sprinkler heads have gears and other moving parts inside. Air acts differently than water, and blowing hot air through a rotor head for extended periods can damage the gears and shorten the lifespan of the rotor head. This means you could damage your irrigation system by blowing it out for too long in an attempt to expel every last drop of water.

What is cross connection testing?

It is the testing of the device used to protect your municipality’s potable water supply from backflow contamination. In Calgary, it is required by the water purveyor for these devices to be tested every year. A cross connection on an irrigation system must be tested yearly and before the irrigation system is turned on.

Are cross connection tests required in Calgary?

They are required annually wherever there is a cross connection that could potentially contaminate the water supply. Underground sprinkler systems are a prime example, as dirt and chemicals such as herbicides or fertilizers can enter the system unnoticed over time without causing other issues. The City of Calgary requires you to have your sprinkler system’s cross-connection tested before the system is activated each year.

These tests are mandated by section 39.3e of the City of Calgary’s Water Utility Bylaw. This reflects a similar mandate in the National Plumbing Code of Canada, as do identical bylaws in countless other municipalities.

What is a sprinkler cross connection?

A sprinkler cross-connection is where the sprinkler system hooks up to the potable water supply. A sprinkler cross-connection is where the sprinkler system hooks up to the potable water supply. That’s why a backflow prevention device (typically a Double Check Valve Assembly) is needed at that location. As per the National Plumbing Code of Canada, DCVAs is recommended for most modern residential irrigation systems.

What is the most common cross connection?

The most common cross connection is a hose attached to a garden tap.  If this garden tap is hooked up to an irrigation mainline, a cross-connection device should be installed where the irrigation water line hooks up to the potable water supply. It should have a hose bib vacuum breaker if it is a regular garden tap.

How do you turn on underground sprinklers?

How much will an installation cost?

It all depends on where you live and the size of your property.  In and around Calgary in 2022, $6,500-$8,500 for a complete residential underground sprinkler system, including mainline, pulling a permit, Wi-Fi timer and sprinklers.

The smallest residential irrigation system we installed in 2022 cost $4,500, and the most expensive was $15,000.

How do you install underground sprinklers?

We use a vibratory plough to pull most poly pipes into the ground. This will still cause some scarring of the turf, but way less than hand-digging trenches. Some hand digging will have to happen, but only where there are underground utilities, sprinklers, valve boxes, mainlines, pipe connections, tight areas, etc.

With residential irrigation installs, irrigation pipes are installed 4-8 inches (10 cm to 20 cm) deep. The pipes need to be deep enough so that they do not get damaged by things like aerators.

Are underground sprinklers worth it?

Underground sprinklers typically do not add monetary value to your property, but they increase the odds of selling it quickly. Underground sprinklers are becoming more popular and are a definite selling feature. We can save money on water bills by installing smart Wi-Fi timers, flow sensors, and rain sensors. An automated system will require very little time and attention. A quality installation will last for a long with little maintenance, except for the fall blowout and cross-connection test.

Can I install a sprinkler system myself?

Yes, you can contact your municipality about the need for a permit. In Calgary, you must pull a permit for the cross-connection installation. Typically, a Double Check Valve Assembly is installed and has to be tested yearly by a certified cross-connection tester. Someone must do that part of the irrigation system.

How do you calculate the irrigation flow rate?

  1. Determine what type of sprinkler nozzles and heads you will use and your static pressure. Typically speaking:
    • In Calgary, we would expect to see the pressure between 40 and 60 psi (275-414 kPa)
    • Rotors need 50 psi (345 kPa)
    • Rainbird R-Van Rotary nozzles need 45 PSI (310 kPa)
    • Hunter MP Rotator nozzles need 40 PSI (275 kPa)
    • Spray Nozzles need 30 PSI (207 kPa)
    • Drip lines need 25 PSI (172 kPa)
  2. Once you know what operating pressure you need, attach a pressure gauge upstream of a ball valve and hook this up to a garden tap on the house.
  3. To determine your flow rate, open the garden tap and the ball valve enough to get to the operating pressure (dynamic pressure) you want. Once there, you can use a 5-gallon (19 L) pail to get the flow.  If the five-gallon pail fills in 1 minute at a dynamic pressure of 40 psi, you know you have five gpm (19 lpm) at 40 psi (275 kPa).
  4. If you were to simply open the tap all the way and do the flow test, you would get a flow rate based on little or no pressure, which would not be accurate. By not starting your design process with a proper flow test, you would end up with an irrigation system that costs more than it should or may not even work.

What is the best way to take care of your lawn?

A lawn needs air, nutrients, and water.  Ensure that it gets all three to best take care of your lawn.  In Calgary, we have clay soil so aeration is needed and we would suggest at the very least it should be done yearly.

Feed your yard with the right type of fertilizer. (We would recommend hiring a professional company to do that service for you.)  As for water, we do feel is it best to have an underground sprinkler system with a Wi-Fi irrigation timer, such as the Hunter Hydrawise.

A smart Wi-Fi timer like that will adjust run times based on local weather, watering less when it is cold and wet and more when it is hot and dry.

Is it worth paying for lawn care?

Yes, a professional lawn care company will provide quality work that will help you save time.  It is best to sign up for a weekly contract so that your lawn can be cut regularly and will have consistent care.

The healthier your lawn, the more enjoyable it will be for your family. A well-kept yard may even increase the value of your property.

When should I start watering my lawn in Calgary?

It is best to start watering early in the morning before it gets too hot or windy. Generally speaking, we have a lot of clay in our soil, so you do not need to water every day.

If you do not have a smart Wi-Fi timer that can adjust to local weather conditions, you should check the soil’s moisture level before watering.

How much does snow removal cost in Calgary?

Some residential snow removal companies charge as little as $100 per month, and others charge over $300.  The size and layout of your property are the most critical factors.

Other variables include how many jobs each snow removal worker must do daily. The more jobs a labourer has daily, the less you pay, but the longer it could take for them. If your neighbours have a snow removal contract with a company, pay attention to that company when it shows up after a snowfall. Try searching for available snow removal contractors online and reading customer reviews.

You can usually get the best rate from a neighbour kid because they do not have to drive to your house to remove the snow.  On the other hand, snow removal contractors often have some means of documenting when the snow removal happened and supplying you with pictures. The necessary software can cost the snow removal company more money but provides timely and accurate details about when the snow removal was done, giving you peace of mind.

What is a reasonable price for snow removal?

In Calgary, $200-$300 per month. Clients with larger properties, longer driveways, or more areas that need clearing to support their daily routines (for example, an extra path between a side door and outdoor garbage bins) can expect to pay an amount toward the higher end of this range.

How do I budget for snow removal?

Typically, it is a monthly expense rather than per snowfall, as most snow removal workers must be on-call for the whole season.  In Calgary, we recommend signing a contract from November 1 to April 30th. If you pay $200-$300 per month, you should budget $1,200-$1,800 per year for an average house in Calgary.
