Why Lehi Homeowners Trust Water Damage Specialists
- Licensed Utah plumbers (Contractor License #7033426-5501).
- Plumbing and restoration in one company. We fix the cause and the damage, so one call covers repairs, cleanup, and plumbing emergencies.
- HomeAdvisor Top Rated. Read our reviews.
- Background-checked technicians you can trust in your home.
- Most homeowners in Lehi call us for recurring plumbing problems, and Lehi homeowners frequently experience sewer backups and leaks; we also help catch sewer line problems and hidden leaks before they cause bigger damage. Hidden leaks can cause thousands in damage. Water stains are another common warning sign. Our leak detection process helps us understand what is happening inside the line or wall before opening finished areas, and repeated leaks or backups in the same area can mean the same problem is returning because of damaged pipes or developing sewer line issues. A slow drain in one sink is usually more localized, while broader backups may require professional drain cleaning. When sewer line issues involve tree roots or heavy buildup, hydro jetting may be used to clean the pipe wall thoroughly. That quick response also helps limit mold growth, and in emergency plumbing calls, our team works to identify the actual source of the failure instead of only fixing surface damage.
- Written estimates before work begins, with same day service when available for urgent local calls. This is one reason homeowners choose to act before a small leak turns into a larger repair.

Water Pressure Regulator Installation in Lehi
A pressure reducing valve, also called a water pressure regulator, is a bell-shaped brass valve installed on the main water line where it enters the home. It takes whatever the city sends and drops it to a safe, adjustable setting, typically 50 to 60 psi. In Lehi, water hardness is about 350–400 ppm, and that hard water can affect the home's plumbing, Water Heater performance, and other plumbing systems. A water softener replaces calcium with sodium ions to create soft water, helping limit scale buildup, improve water quality, protect the home's water quality throughout the house, and extend Water Heater life in Lehi homes.
If your home was built without one, or a previous owner removed it, a PRV installation from Water Damage Specialists includes:
- Pressure test before and after
- Installation on the main line after the shutoff valve, before any branches
- A new shutoff valve if the existing one is corroded or seized
- An expansion tank on the Water Heater when required, since a PRV creates a closed system that needs somewhere to absorb thermal expansion; a thermal expansion tank helps protect the system, and in Lehi hard water can leave sediment because sediment insulates heating surfaces, causing reduced hot water capacity and shortening Water Heater life unless expansion tanks are paired with a water softener
- Setting and verifying the outlet pressure
In hard water areas, Water Heaters often last only 8 to 10 years without good pressure control and maintenance.
Pressure Reducing Valve Replacement in Lehi, Utah
PRVs wear out. The internal diaphragm and spring lose their ability to hold pressure, usually after 10 to 15 years, and sometimes sooner in Lehi because hard water scales up the valve internals.
Signs your PRV has failed:
- Pressure has crept up over time even though the setting hasn't changed
- Pressure fluctuates or surges when fixtures turn on and off
- No water pressure change when you adjust the screw on the valve
- Whistling or humming from the valve
- Leaking from the valve body or bell housing
- Low pressure throughout the house from a valve that's stuck closed or clogged with scale
We replace the valve with a quality rebuildable PRV, reset the pressure, and check the expansion tank and water heater relief valve at the same time, since a failed PRV often takes those with it.
High Pressure Already Caused a Leak?
Water Damage Specialists is a full water damage restoration company as well as a plumbing contractor, so if a hose, fitting, or water heater has already failed, one call covers everything, with Emergency plumbing available 24/7 in Lehi, including holidays, and urgent calls typically answered in under two hours rather than waiting for normal business hours:
- Emergency plumbing to fix the failure and install a PRV when burst pipes or major water leaks need to be addressed immediately
- Emergency water extraction and structural drying
- Mold remediation if the leak went unnoticed
- Reconstruction to repair drywall, flooring, and finishes
Hidden leaks can cause thousands in damage before detection and may show up as a higher water bill, musty odors, or damp carpets.
Leak detection uses acoustic listening and infrared imaging to locate slab leaks and leaks in exterior walls before opening finished areas.
That quick response also helps limit mold growth when water intrusion is left untreated.
We document everything for your insurance claim and can bill most carriers directly.
Water Hammer Repair in Lehi
Water hammer is the bang you hear when a fast-closing valve, like a washing machine solenoid, dishwasher, or single-lever faucet, stops moving water instantly. The shock wave travels back through the pipes and slams against fittings, joints, and hangers. Over time it loosens connections and cracks pipes.
High water pressure makes it much worse, so the first fix is usually a PRV. From there we address the noise directly:
- Water hammer arrestors installed at washing machines, dishwashers, and ice makers
- Pipe strapping and support to stop loose pipes from banging inside walls
- Air chamber recharging on older homes plumbed with vertical air chambers
- Slow-closing valves where appropriate
If the hammer has already cracked a fitting or split a supply line, we handle the plumbing repair and the water cleanup in the same visit.
PRV Replacement Cost in Utah
Typical pricing for Utah homeowners:
| Service | Typical Range |
|---|---|
| Water pressure test and inspection | Free with estimate |
| PRV replacement (existing valve) | $350 – $800 |
| New PRV installation (no existing valve) | $450 – $1,100 |
| Expansion tank installation | $200 – $500 |
| Water hammer arrestors | $150 – $400 per location |
| Main shutoff valve replacement | $200 – $500 |
Price depends on the valve size and grade, whether the main line is accessible or buried in a finished wall, whether the shutoff valve or expansion tank also needs attention, and in Lehi City, whether potable water system work may require a permit or inspection under local Utah code where applicable. Every job starts with a free estimate, upfront pricing, and a written price with no hidden fees.
For comparison, a burst washing machine hose caused by high pressure routinely leads to $5,000 to $15,000 in water damage on a finished basement. A PRV is one of the cheapest pieces of insurance you can put in a house.

High Water Pressure in Lehi Plumbing System
High water pressure is one of the most common and least noticed causes of water damage in Lehi homes. It quietly wears out supply lines, appliance hoses, and fixtures until one of them lets go, usually while nobody is home. Water Damage Specialists installs and replaces pressure reducing valves (PRVs), repairs water hammer, and fixes the damage when high pressure has already caused a leak. Licensed plumbers, headquartered on State Street in Lehi since 2007.
Free estimates. Written pricing before work begins. Licensed and insured.
Lehi's water system serves homes spread across a huge range of elevation, from the valley floor near Utah Lake up to Traverse Mountain. To push water uphill to the highest neighborhoods, the city runs its mains at high pressure, which means homes at lower elevations can see street pressure well above 100 psi. Plumbing code calls for 80 psi or less inside the home, and most fixtures and appliances are designed for 40 to 60 psi. A failing water pressure regulator can also cause low water pressure or inconsistent flow, not just pressure that's too high, so ongoing changes in pressure often point to bigger plumbing problems.
Signs your water pressure is too high:
- Banging or thudding pipes when a faucet or appliance shuts off (water hammer)
- Faucets that spray or splash hard
- Toilets that run or refill loudly
- Dripping from the water heater temperature and pressure relief valve
- Short-lived washing machine, dishwasher, and ice maker hoses
- Frequent drips from faucets and showerheads
- A water heater that fails well before its expected lifespan
A simple pressure gauge on an outdoor spigot will tell you what you're dealing with. We test pressure on every service call and will tell you if yours is out of range.
