Stop and waste valves in Utah
Stop and waste valves are also known as main shutoff valves or irrigation shutoff valves. They are brass valves tied to your culinary main water line, usually deep underground, and are where you turn water on and off to your landscape sprinkler system and drip irrigation. They should be replaced only by experienced professionals like our team.
Depth is almost always about freeze protection: valves can run from about three to eight feet deep, but four to five feet is typical. They are buried deeply so they never freeze. The valve is usually on a direct path between the water meter and the home, often near the meter; the closer to the home it sits, the deeper it tends to be.
These valves are designed to release a small amount of water temporarily when the valve closes. They can also release water when the stem is not fully open or fully closed—even about five percent open can produce a continuous leak. We never replace a valve unless it needs replacement. If it is only slightly open, you would typically pay a small service fee and our team will take care of it for you. A shutoff that does not fully close is also a winterization risk: water can keep feeding the irrigation system after you think it is off. Read our Utah sprinkler winterization guide before freeze weather arrives.
Replacement pricing depends on depth and obstacles when digging and generally ranges from about $1,950 to $3,500, with most jobs toward the lower end of that band. Old galvanized main lines often require a full main line replacement as well—commonly about $5,000–$20,000 depending on the property—which must be completed by a licensed plumber. See our pricing page for published ranges.
Warranty: all of our repairs, including stop and waste valves, are backed by a five-year parts and labor warranty when you enroll in a Storm Shield maintenance plan.
Secondary water: most cities on secondary water do not use a deeply buried stop and waste the way many culinary systems do. Lehi is an exception, where pink secondary water meters can appear alongside deeply buried stop and waste valves on culinary irrigation.
Some homes use a basement shutoff for the sprinkler system instead of an outdoor stop and waste; on culinary water in Utah, outdoor stop and waste setups are still very common. Commercial and larger properties may have multiple stop and waste valves.
Signs of a leak: water in the access tube, puddling around the shutoff, or the meter box filling with water when the valve is close to the meter. You can also watch the water meter with the valve open and no sprinklers running: if the dial counts up, that points to a leak on the irrigation side.
We also install stop and waste valves for homeowners who are adding a sprinkler system or converting from secondary to culinary water. Wondering what is going on at your property? Call us for a phone estimate at no charge.
