We recently replaced our water heater and now the water to both toilets is running intermittently. The water is also running to a spigot on the outside of the house causing the faucet to drip all day. What could the problem be and how do we fix it?

Do you have a PRV (pressure reducing valve) installed? (see image) What's the house PSI? Check the tank levels ion the toilets. They should be 1/2" under the white overflow tube. Back to you. Tom
