We are about to build a new house on a slab. Is there any way to minimize the temperature change in a shower, as when someone turns on another faucet, flushes the toilet, etc. Maybe pipe circuitry, or sizes? Thanks.

There are several options open. You may purchase and install a Scald-Guard shower valve, this is a valve that adjusts for temperature and pressure changes or a less expensive way would be to install a regular shower valve and direct your plumber to pipe the cold supply with a dedicated 1/2" supply taken directly off the house main. This removes the danger of anyone flushing the toilet and toasting your buns with a burst of hot water. I live in a slab home in Florida. Good luck, Tom`

galveston--
I suppose you are posting from Galveston,TEXAS--if so, I am also a resident and have done some creative design on this problem you might be intersted in. I don't think anyone is making it yet, but I am about to try a prototype.

ktomas,
No, actually, its my name. Thanks for the contact, but the slab is poured now, and I have put dedicated lines to the showers. If you have something that works, there are probably lots of people out here who would be interested.
