Questions that come up on fixture jobs
I bought the fixture online, will you still fit it?
Yes. Send the model number or the spec sheet beforehand so the rough-in dimensions can be checked against what is in your wall.
The maker coverage on a fixture you bought is a matter between you and that manufacturer. This site makes no promises of that kind about the work.
Surely I do not need a permit just to change a shower valve
Sometimes you do not. Clark County Code 22.02.195 exempts repairing leaks in pipes, valves or fixtures, as long as concealed piping is not replaced or rearranged.
The exemption stops the moment the pipe behind the wall is changed. That is why the department for your address gets asked before a price is quoted.
Why does the wall have to be opened at all?
A tub and shower mixer lives inside the wall, connected to hot, cold and the riser. There is no way to replace the body of that valve from the front.
Where a home has a rear access panel in the neighboring closet, the wall can often be left alone. That gets checked before anything is cut.
My house is from the 1950s, is that going to be a problem?
It changes the approach rather than blocking it. Galvanized supply pipe was common from the 1920s through the 1950s and has a 20 to 30 year life.
Old threaded galvanized can crack rather than unthread. In neighborhoods like Huntridge, built 1941 to 1944, that possibility is discussed before work starts.
Can I do the trim out myself and just have the rough-in done?
That split is normal on remodels, and plenty of homeowners handle the visible parts. Be clear about it up front so the rough-in is left ready for you.
Nevada does exempt small jobs under $1,000, but not where a permit is required, and not for work of a type a plumbing contractor performs.
