Fixture and valve replacement

Faucets, valves, shower trim and cartridges replaced. Often the cartridge is the whole repair, and we will say so.

One flat fee to find out what is wrong. You are told it on the phone before anyone is dispatched, and it comes off the job if you hire us. Read our Plain Terms

A black spring-neck kitchen faucet with a pull-down sprayer and a separate soap dispenser, newly set at a white quartz counter over a dark sink
A spring-neck kitchen faucet, set and sealed. St. George, Utah.

What the work is

A shower that has gone stiff, a tap that drips, a valve that will not hold temperature. On this water the usual cause is mineral scale on the cartridge rather than a worn body, and a cartridge is a fraction of the cost of a fixture.

We carry the common cartridges and we will fit one rather than sell you a fixture where that is the honest answer. Where the body itself is scaled or the trim is obsolete, we will show you why and quote the replacement.

What is included

  • Diagnosing whether the fault is the cartridge, the seat or the body
  • Cartridge, seats, springs or trim as required
  • New supply lines and stops where we are already there
  • Testing under pressure and under real use before we leave

What is not

  • Opening a wall to reach a valve body, which we will show you and quote first
  • Tile repair where a valve has to come out through the finish
  • Sourcing obsolete trim, if it no longer exists. We will tell you before you book

Why yours keeps doing this

A mixing cartridge furring up with white mineral scale is what this water does. Replacing the cartridge fixes today; treating the water changes the interval.

If you are on your third cartridge in three years, the fixture is not the problem.

What to ask anyone quoting this, us included

  • Is this the cartridge or the valve body?
  • Do you have the cartridge for this brand on the truck?
  • Why does it keep happening?

What we can show you in writing

Every line traces to a document we read in full. The number after a sentence points to the research below.

  • Cartridges and fill valves that fail early are often a pressure problem, not a fixture problem. A waterlogged expansion tank lets pressure spike, and the cartridges go first. We check static pressure before we blame the fixture.1
  • St. George water carries 118 to 936 ppm of dissolved solids. Shutoff valves seize in it, and a stop that has not been turned in fifteen years may not turn now.1
