The faucet to my tub keeps turning itself on. It starts with a drip which gets bigger until the water is coming out full force.
I turn it off and in a few seconds it repeats itself.
This usually follows filling the tub. After turning it off several times, it seems to stayoff.

At 6:00 this morning, it came on and woke me up.

What is going on? How can we fix the problem?

What's the brand name of the valve? What's the PSI of your house water pressure? Do you have a PRV, (Pressure Reducing Valve)? Regards, Tom
