Question about RELIANCE ELECTRIC WATER HEATER

1 Answer

I need to drain my Reliance electric water heater. I will use my garden hose to drain the water to the outside. Problem: none of my 3 garden hoses will screw onto the drain faucet fitting on the water heater. All 3 hoses will fit any other faucet at my home. Is it possible that the water heater drain fitting is metric? If yes, where can I buy an adapter for it? Thanks, Howard Kress Kill Devil Hills, North Carolina 27948 252-441-5137

The drian hose fittings on many water heaters are a cheap plastic that are mass produced who knows where. For this reason and others, the thread paters are not always perfect. All hose threads should be the same. Installing a new (brass) drain valve will solve the problem. You can call Reliance and ask for a free replacement if your heater is still under warranty.

WOULD SOFT WATER HAVE A BAD EFFECT ON THIS MODEL AS IT HAS RUSTY BITS


Hot water heaters are a collector of sediment. The proper care includes flushing out the collected debris through the low side drain faucet. The problem is the faucet is not designed correctly to carry out the needed task. If you are handy... turn off the water and gas or electricity to your water heater. Relieve the water pressure through the temperature/pressure relief valve on the side of the water heater tank. Once pressure is relieved close the valve. Determine if you have a 1/2 inch or a 3/4 inch diameter drain valve hole in the side of the tank where the drain valve is located. The drain valve can be removed with channel lock pliers, an 8 or 10 inch adjustable wrench, or a small 8 to 10 inch pipe wrench. Water will leak out the threaded hole while the valve is out. If everything is closed maybe 2 cups of water will leak out of the hot water tank as you check drain valve thread size. DO NOT take your time checking thread size. After you know the pipe thread size go to the hardware store ( Home Depot, Lowe's etc) purchase a short nipple (1 1/2 to 3 inch depending on available space) and a ball valve (brass) due to the water temperature. You will also need a brass adapter for pipe thread to garden hose thread (male both ends). This adapter goes into the ball valve to allow for the connection of a garden hose. Connect the pipe and valve together using the correct pipe thread sealant and install in place of the original plastic drain valve. Install pipe to hose adapter using thread sealant. With the ball valve in place turn the water back on. Gas or electricity back on. Connect a garden hose to the ball valve. Place the other end of the garden hose in a safe area as hot water and debris will be expelled through the hose. With water on, Gas or Electricity on and the relief valve closed actuate the ball valve to the full open position for approximately 3 seconds then close the valve. Repeat the open and close of the ball valve three times. Observe the debris that emptied out of the garden hose. You may be surprised at what you see. If the water runs clear, disconnect the garden hose the task is completed. You can wait until the following year to repeat the process. Your pipe and valve are now a part of the water heater, they may remain in place. Put the hose away.

Popping noise in water heater. What is it and how do I fix it?


What is probably happening is that you have a build up of minerals on inner tank lining and when unit is heat it expands the tank and the deoosits at a different rate which is what is causing the popping noise.
I would turn power off to your heater and hook a garden hose on to drain valve.Route hose to safe area as the water being drained will be hot. Open drain valve and see if you can get it draining good.If it is then shut off water supply to heater and open hot side of faucet nearby to prevent vacumn from slowing down draining. I would drain as much as I could then close drain valve and faucet and refill tank. I would do this several times to try to get all sediment flushed out.Hopefully this will help with your noise and make your heater last longer and work more effceiently. Good luck and thank you.

I need to replace the drain valve at the bottom of the tank,can I buy a replacement valve? Are they all the same size?


There are 2 sizes; 1/2 inch and 3/4 inch. Remove the old one after draining the water heater and shutting off the water supply then take your old one to a plumbing supply outfit like George Morlan's. Make sure you wrap the new threads with teflon tape at least 3 wraps while holding the spigot in your left hand so the tape won't come off as you install the spigot. Good luck!!

How do I change the heating element on my 50 gallon electric Reliance 501 hot water heater? Where can I get the heating elements?


Buy elements at local hardware store or home center, like Lowes
Look at label on side of tank.
Label shows element wattage.
Element is also printed on end of element in tiny letters-numbers.
Typical elements are 4500 and 5500 watts.
Tank needs 10 gauge wire and 30 amp breaker for 5500 watt element.

Water heaters are fully repairable by homeowner.

1) Have you tested water heater to see if element is problem? You need cheap multi-meter from Home Depot.
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

2) To change element
a) turn off power
b) drain water from drain valve ... once it starts draining, loosen element slightly while tank still has weight to hold against you turning element wrench.
Here's what to do if water heater won't drain:
http://waterheatertimer.org/Water-heater-will-not-drain.html
c) open covers on tank, remove element using element-wrench from hardware store or home center.
If element won't come out:
http://waterheatertimer.org/How-to-remove-old-water-heater-element.html
d) Clean out tank if needed.
e) Replace element.
f) Fill tank entirely with water before turning on power or element will burn out.
g) Once tank is filled, and water flows steady out of tub spout, turn on power.
Each steps above is shown on following link:
http://waterheatertimer.org/How-to-clean-sediment-out-of-electric-water-heater.html

3) You need to buy some things:
Screw-in type (not bolt-in type) Element that matches wattage on tank label. New Element comes with washer.
Inexpensive Element wrench.
Inexpensive multimeter if you are going to test parts first.
Some pieces of pipe and hose if tank sediment needs to be cleaned out.
Washing machine hose if tank will not drain (return after job is done).

4) Also:
You need flat tip and phillips screwdriver.
Lighting to work on tank
Some WD-40 if element is stuck in place.
Garden hose to drain tank.
Shop vac and duct tape if you need to vacuum out sediment.
Tarp to protect floor and carpet
Maybe a knife to cut back insulation on wire if wire is burned at element.

Web links above go through entire process step by step.
Add a comment if you need more help, I'll be back around 5 CST

1992 Reliance electric water heater model 501 has two 4500 watt heating elements , there is no hot water.


Check the breaker and top thermostat and make sure they are not tripped. Move onto replacing elements if above is not the problem.
Turn water and power off to heater and attach a water hose to bottom of heater to drain down tank. May have to open hot side on a facuet to get it to drain.
Once drained remove elements with 1 1/2" found at local hardware stores. once elements removed and new ones in place. Turn water on and get the air out of the system. Once water is flowing from the hot side from all of facuet's in house.
Once all air is out now yaou are resady to turn power onto heater.

Need to empty reliance 501 hot water heater how?


1) Shut the breaker off to it at the panel. 2) Hook a hose up to it (the bottom has a drain). 3) Close the valve to the water heater (on the cold water supply). 4) Open drain on the bottom of water heater. 5) Open the relief valve to allow air into the tank (it won't drain otherwise - think if you put your finger on one end of a straw - the liquid stays in until you let go). Why are you draining it by the way?

Flooded bathroom from top of unit


The T&P valve (temperature and pressure) relief valve is suppose to have a 3/4 in drain line threaded into it .This line should have ran to a trapped drain or possibly to the outside of the house. A water heater cannot over fill. To drain your water heater run a garden hose to the outside or to the lowest drain you have nearby.If its still wet be carfull not to get shocked,Attach the garden hose to the drain valve located towards the bottom of the water heater. turn the valve on. If water dosnt come out of the other end of the hose,youll have to see if you can run a peice of wire through the valve into the water heater to get it to drain. This can somtimes be a real problem . I usually leave the water on when i first connect the hose to the drain valve. This allows the water pressure to flush the sedament out of the bottom of the water heater.

How to drain the rheem 135 litre tank


1. turn off the electrical power first.
2. attach a garden hose to the hose bib attachement on the bottom of the water tank and run the hose outside to allow the water to drain out by gravity.
3. Turn the valve that is on the inlet of the water heater. Now that the power is off, you can drain the tank.
4. open the drain valve where the hose has been attached.
5. To release the pressure, you can open a hot water faucet in your kitchen. This will allow the water to drain out easier.
