If you have an expansion tank in the water line near the hot water tank there may be a small plastic cover over a valve that looks like it is an air valve from a tire/tube. If you depress it and water comes out it means the tank inner membrane is compromised. Replace the tank. Home Depot has them. They're about 3 or 4 gal and adequate for a typical home situation. The pressure relief valve leaks because when you use the hot water it comes out of the hot water tank and is replaced with cold make-up water from your water supply. As it heats up it expands. Since the expansion tank is full due to the leaking membrane in the expansion tank, the expanded water goes out the expansion valve til the pressure is equalized. I put a small catch pan under it til I could replace the exp. tank. Be careful when you remove it(mine was simply screwed into a fitting in the water line) the tank as it will be heavy and awkward. Goog luck.

Water backing up into brine tank?
There are two main causes of water backing up into a water softener brine tank. The injector assembly may be defective and not draw all of the brine out of the tank and then the timed brine refill will put back a predetermined amount of water, causing the level of brine to increase in the tank after each regeneration. The other cause may be a defective brine valve which has a slow leak after it closes and causes the tank to overfill.
Can you shut off the inflow valve to hot water heater for a day without harming system if so should pressure valve be left open and limited usage of hot water?
If you have a leak on the hot water somewhere in the house and the water input into the tank is not running, the tank will lose it's water. And if it is an electric tank, the elements will burn out. Gas hot water tank should be no problem. Pressure valve does not have to be open.
Which part of a toilet tank assembly is the supply valve for water to the tank?
That is a fill valve and is part of the ballcock system. When someone pulls the lever, that pulls the chain and lifts the flush valve flapper and empties the tank into the bowl. That causes the float to drop, opening the fill valve and allowing water from the supply to enter and refill the tank.

Can you help me with this water heater leak please?
If the tank, shut the water off and drain with a hose on the drain faucet on the bottom of the tank. The pressure relief valve can be replaced (however a PRV is meant to drip, it has to expand.), so can vacuum breakers and the TP valve.
How do you do a hot water system check?
Turn off the hot water to your tank and do not use any water -- and leave it off for about 30 min. -- then turn your valve back on and if you hear water going back into tank you have a leak somewhere
What could cause Your water heater has a constant leak from overflow into tray at bottom of tank.?
It could be a bad overflow valve or the thermostat could be set to high and the heat is creating the leak. Also, if the test lever on the TPR valve is 'tested' or lifted, it is possible, if not likely that sediment inside the tank gets lodged in TPR valve preventing it from closing. This will create a contiuous leak from discharge tube into pan until valve is successfully closed.
