|In response to Re: faucet use activates toilets|
: : I have 3 Kohler low boy toilets, Rialtos I believe, with the 3.5 GPF. When I turn a faucet on in the house and then off, with fairly good consistency, the toilet will run for a bit? Average water pressure is 55-65 PSI in my city. What is the deal? This is just one of my peeves with these toilets. They were in the house when I moved in.
: The only possible explanation for your problem is that the float valves in your toilets are too sensitive to sudden changes in watter pressure caused by opening and closing a valve elsewhere on your water supply line. I've never seen this myself in over 25 years of plumbing. Maybe someone else here has.
Your fillvalves need to be replaced and while your at it check the pressure coming into the house. A bad regulator can also be contributing as well. The pressure should be about 65 psi and only fluctuate about 5-8 psi when a toilet or fixture is used. Any more then that means you may need to change out your regulator. Good luck.
