Why Doesn’t Your Irrigation System Have Any Water Pressure?

Having an irrigation system in Tennessee is a game-changer when it comes to keeping your lawn and landscape hydrated. However, if you've noticed a decrease in water pressure, a few things could be causing it. A broken water pipe or an obstruction in the lines of your irrigation system could contribute to lower water pressure, as can clogged sprinkler heads. There's also the possibility that the main water or backflow preventer valve is malfunctioning, restricting the flow of water or stopping it altogether. If you have concerns about your irrigation system's water pressure, you'll want to contact pros, as they'll be able to identify the issue and promptly repair it.

A broken pipe could be causing your irrigation system to have low water pressure.

If your irrigation system has a cracked or broken pipe, it can cause low water pressure due to the water escaping. Low pressure can affect the even distribution of water from your sprinklers, which can result in brown patches on your lawn. If there is water pooling in one spot on your lawn, it can indicate where the damage to your water pipe is located. This usually occurs around or between sprinkler heads. However, finding the broken pipe can sometimes be challenging, as most of the water lines are located underground.

Your irrigation system's low water pressure could be from the backflow preventer valve malfunctioning.

Another potential reason your irrigation system has low water pressure is the backflow preventer valve is malfunctioning. A backflow preventer valve is responsible for keeping the water flowing in one direction, preventing contaminated water from backtracking into your drinking supply. If your backflow preventer valve is not fully open, it can restrict the flow of water and, therefore, your water's pressure. If half the water that's supposed to be coming out of your sprinklers isn't, then the weak flow of water won't be able to reach all the areas on your lawn.

Clogged sprinkler heads and obstructions can lower your irrigation system's water pressure.

Another cause of your irrigation system's low water pressure could be clogged sprinkler heads and obstructions within the lines. Debris and calcium build-up can block the flow of water from the sprinkler heads and throughout the irrigation pipes. If it continues to collect, the decrease in water pressure will likely worsen and further inhibit the watering of your vegetation.

Your irrigation system's main water valve might not be fully open, causing low water pressure.

Your irrigation system's main water valve might not be fully open if you've noticed low water pressure. If your irrigation system hasn't been used for a while, the valve can get stuck due to corrosion or rust. There could also be a break in the mechanism that controls the opening and closing of the valve. This can be caused by mechanical wear and tear or damage to the valve body. In some cases, an electrical component may not be functioning properly, preventing the valve from opening or closing.

What should you do if you notice signs of low water pressure with your irrigation system?
