What this site is
ShowerValve is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands, and valve work opening a wall is often a permitted alteration — ask to see the permit. We carry out no work, we sell no valves, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call. The maximum water temperature is set by your local code, not by this website.Checking a credential in Iowa
Iowa licenses are issued by the Iowa Plumbing and Mechanical Systems Board, which publishes a public search you can use before work begins.

What that coverage looks like
Des Moines, at 55 ZIP codes, is the largest part of our Iowa footprint, and Polk County holds 62 of the 150 we cover. A valve job needs the right cartridge in the van, so the call asks what the trim looks like and how many handles it has before anyone is sent.
How a shower valve replacement job goes
A shower that will not hold temperature is a cartridge far more often than it is a valve. The cartridge sits inside the valve body behind the tiles and can usually be drawn out through the trim plate without opening the wall. The wall comes off when the body itself is cracked, seized into the pipework, or no longer made in a form that fits.
What the call asks about shower valve replacement
- How many handles the shower has, and whether the trim plate is round or square.
- Whether the fault is temperature, pressure, or a drip that will not stop.
- The maker if it is stamped on the trim, because that identifies the cartridge.

A valve that will not hold temperature is a cartridge far more often than it is a valve. The pages above say how to tell before the tiles are touched.
