Plumbing pressure relief
I'm running on internal water (not city water). I don't leave the water heater turned on all the time (too wasteful to do so) and when I turn it on it raises the pressure in the whole plumbing system way too high, and I get water leaking from the toilet onto the bathroom floor. The only way I've found to deal with this is to shut off the pump and briefly open a faucet every 10 minutes to relieve the pressure, until the heater gets hot and the pressure stabilizes, which gets pretty annoying.
There is a pressure relief valve on the water heater, but apparently it's only intended to protect the heater tank, and opens at too high a pressure to do anything for the plastic plumbing.
Is there some kind of relief valve that opens at a lower pressure, which I could install somewhere in the system and have it drain overboard?
