SOURCE: Dripping Drain valve on rheem water heater

If your water heater is 10 years old or more, it's much better to replace the entire thing before you start having additional problems with it. You MAY be able to drain your water heater and replace the valve with something more reliable, but, as I've said... if your water heater is old, this is just the 1st thing to go wrong. More will follow.

SOURCE: Drain valve on Rheem water

You can do the job.
If the valve is plastic, the valve may break off inside the water heater.

The tank forum which is hosted by a professional plumber says, to use a hammer and screwdriver to remove the plastic drain valve: These guys are the pros.
" If a plastic drain valve snaps, having a hammer, a flat-bladed screwdriver and a towel can get you out of hot water. The towel is to absorb the hot water coming from the heater. You can use the screwdriver and hammer to gently tap the broken plastic piece out of the threads, then install a ball valve drain assembly with pipe-seal tape.
Now another guy at the Tank was saying he drilled out the broken plastic valve.
In any case it can be removed if it breaks.

Install a brass valve.
I just bought one at Home Depot and noticed that Lowes has brass drain valves too.
They're in the water heater department. You need teflon tape or joint compound on the threads.
And if it ever starts leaking, you can put a hose cap on the end, or replace it again.

For professional water heater advice: I go to the tank

SOURCE: Have a water heater drain

Hello tiletnickm, first, the plumber's tape and bottle cap is very clever! GREAT JOB!
Many of those valves do have a stem that can be replaced, however, finding the right parts at the big box stores can prove challenging. If you have a local plumbing supply store they seldom have the part in stock, but can usually order the right part for you.

Something you may consider if you haven't drained your water heater in the past year, ( most manufactureres recommend draining them atleast once a year to prevent buildup and extend the life of the water heater ), it could be much less time consuming to drain the tank and then change the valve.
I hope this is helpful my friend!

SOURCE: This Rheem gas water heater

Provided that there aren't other issues with your heater, changing the t&p may be enough. I say this as they generally do not just fail on their own, but rather, something has caused it to operate. This is either caused by temperature or pressure. Without knowing the age of your heater, it is a bit difficult to advise you as to replace or repair the heater. If you are comfortable that your's has more useful life in it, you can replace the t&p valve. If the expected life of the heater has been reached, you may wish to replace the unit.
To Replace the T&P Valve: Shut off the gas, and close the water inlet valve. Drain the tank down. The best way is to attach a hose to the boiler drain and route it to the outside. This also will help remove silt and sludge that can build up in water heaters, and extend the life of your tank. You will need to take an air bleed to allow the tank to drain. You can do this by lifting the lever on the t&p valve and by opening one of the hot water valves that you heater provides water to. You should hear air being pulled into the heater as the water drains.
There is a tag on your valve. When you remove your t&p valve, take it to the hardware store with you, tag and all. Get an exact replacement, and install according to the directions.
Before you pressure the heater back up, flush water through it through the still open drain. This will stir up and flush out any remaining sediment.
Close the drain, but leave the hot water valve that you opened earlier open, as the tank fills, the air will be expelled down the line. Fill the heater completely, then re-light the heater.
Best regards, --W/D--. Feel free to rate this solution.

How to turn up the temp. on a Rheem mod. 82v52-2 hot water heater

To adjust the thermostat, turn off the water heater. Then remove the access panel(s) and any insulation. The access panels are above the drain valve. Take a small flat blade screwdriver and rotate thermostat dial pointer. (The lower temperature settings are to the right.) Replace the access panel(s) and insulation and then turn on the water heater. Do not remove the protective cover on the thermostat.

Wait for water to heat and then check the temperature at various faucets. Make sure to adjust the anti-scald temperature limiter at any faucet that may be accessed by a small child or adult who might be injured by high water temperatures. (Just put a thermometer in the flowing water. Check the faucet installation information. The high temperature limiter will be under/behind the handle for single handle fixtures.)

I hope this helps.

Water dripping out of drain line on my Rheem Water Heater

The T & P valve is connected to the drain and it may be bad causing it to drip. You could try lifting the lever and then closing it back on it to see if it will seal. Also check the thermostat for heat setting, but than likely it is going bad.

It is a pressure relief valve and normally last about 5 years or more before they need to be replaced. The purpose of this valve is to protect heater from building up pressure and protecting the home, It releases water once the heater reachs beyond the limit of the valve can handle.

It is a standard 3/4" thread and can be removed with a pipe wrench. Just turn power, water off and drain water down to just below where the drain is.

Lowes or Home depot shoul dhave one just ask for a pressure relief vakve for a Hot Water Heater. prices range around $15.00.

Pressure valve releases sometimes , I lose a good bit of water. When i tap the valve handle, it shuts off.

The pressure release valve is a safety feature. If it is leaking alot, it could be that the valve needs to be replaced or it could be that the high temp. shutoff in the hot water tank is malfunctioning.
