I realize I can have the plumber come back on Monday to figure this out, however it took 3 attempts to get him to finish the job despite contact from homeowner and contractor, so I'm hoping to get some advice here.

We just redid a small bathroom in an old home, and it looks great. My trouble is, as I went to take the 1st shower in the new shower - it was lukewarm water and not too enjoyable. The sink gets plenty of hot water, we have a bit of warm water in the toilet tank to prevent condensation, so the problem seems to be simply the shower.

Could this be a problem with our new Delta faucet (one handle model) or with the new pipes, or with the plumbing job itself? Thanks for your help!

Most likely some debris got into the hot inlet on the shower mixing valve, plumber error for not flushing and testing. Call him back, call 2x a day if need be, its his error

Could this be a problem with our new Delta faucet Not so much a problem with the faucet itself but more likely some minerals built up in the pipe walls broke loose and is now clogging the in the hot water inlet ports. The solution would be t shut the water off, remove the cartridge or the seats and springs for debris, Now turn the hot water back on to flush out then supply and open valve body. Reassemble and test, Better mow? Good luck. Tom

Thanks! Actually - we found the problem on Delta's web site... it was an adjustment within the handle that allowed more hot water to enter... a type of antiscald safety thing... so now I have hot water and can enjoy the shower. Thanks for your quick responses!

Hi Mngal

If this remodel had a plumbing permit pulled and an plumbing inspector still needs too come in for a final inspection you need to let the plumber know that you reset the temperature limiting device. However, I doubt that there was a permit issued or the plumber would have set this right to begin with!

For inspection and safety purposes in most areas nowadays, the shower temperature cannot exceed 112-115F.

Just FYI... :)

PS: The maximum temperature to the entire home shouldn't exceed 120-125F.
