Probably not but I think it should have an outlet breather pipe.

SOURCE: Rheem 25 ltr cylinder leaking from top

if it is comming out of the cover , you will need to replace the unit ther is no way to fix the tank,, is it comming out of both the inlet and outlet, if it is just comming out of one wipe it of and look at the threads it could just be the adapter in which case you need to drain it and cut the pipe remove the adapter put teflon tape with pipe thread sealer. put the adapter back on, re attach the pipe, if it still leaks you will have to change the unit, if it is electric make sure you turn it off at the circuit breaker before draining you don;t have to drain it all the way

SOURCE: Can I Use Existing Venting from Old Water Heater?

Late answer to an old post, but no you can't use the existing vent pipe. The tankless systems require Category III vents along with all the accessories required for your installation. I suggest you use a direct vent model with the concentric vent through the wall. Remove and patch the roof penetrations of the old vent or just abandon and let it remain.

Reliance 501 electric water heater


Reliance-Rheem may have changed away from generic parts so you have to buy special order parts from them.
I have not heard of this before for elements... but Rheem does that for other parts.
Avoid Rheem products.
Rheem also makes a 1-3/4" element to fit Marathon water heaters, instead of standard 1-1/2"
Actual thread size for standard water heater is same as 1" pipe, except straight thread instead tapered pipe thread.
See if 1" pipe will thread into water heater element opening.

Hot water heater sweeting from top


Water on top of gas heater can be caused by poor venting, or inadequate combustion.
Make sure water is not coming up from under tank top, indicating tank leak requiring tank replacement.
Have a plumber look at problem to make sure home is not filling with deadly, odorless CO gas.
Inspect pipes that they are not corroded and covered with condensate.
Check that roof cap is in place.
Let heater fire and burn for a few moments so the fire is going good, and then light match just outside the draft hood on top of heater. Blow out match and see if smoke draws immediately into vent and upward.

I have a rheem heater M/N 81V40D how do I change the anode?


Unless you see a large hex head socket to remove on the top of the water heater, many
anode rods are built onto the hot side nipple. They are almost the length of the water heater.
Hopefully you have room to remove it if this is the case. If you see a hex nut that is silver
gray on top, then shut off cold water to the heater. Release some hot water at a tap to relieve
pressure on the tank or drain some out at the bottom which is better. Make sure power is
off to unit first or gas is off . Unscrew nut or nipple counterclockwise to remove. Best to
remove with a socket wrench or box wrench if it's a nut and a good pipe wrench if it's
on the nipple. Several light taps with a hammer if necessary on the handle of the
wrench or pipe wrench should help. Hopefully the nipple has a removable flex line if
it's located there. (Remember it's on the hot side and should be marked on the top
of the heater).

I am losing water pressure, but only on the hot side. Cold pressure is fine, as you add hot the pressure fades, the hotter the less pressure. This is at all points in the house. The water heater was...


You have a clog in the hot water line.
If problem is at one faucet, then remove aerator and clean, then disassemble lines underneath sink.

If problem is at every faucet, then that moves search close to water heater.
Look at hot water line that exits water heater and trace that line to first Tee.
Look at cold water line that enters water heater and trace that line to Tee.
Clog is located between those 2 Tees.

Buy pressure tester that connects to hose thread.
geno_3245_251.jpg
Connect pressure gauge to hot water heater drain valve.
Then conduct same test you did at faucet.
See if pressure drops at tank.

If pressure drops, then clog is on cold side of tank, and probably hot side too.
If pressure does not drop, then clog is on hot side of tank.

Suspect 1 is any place two different metals join. For example galvanized pipe and copper.
Suspect 2 is supply pipes that exit top of tank. Take apart and look inside pipes for corrosion and sediment lining pipe walls.
Suspect 3 is elbow. Disassemble pipes and look for sediment and flakes of rust.
Suspect 4 is all suspects above, each having sediment and corrosion.

Water heater will not heat water


There are a lot of causes.
First step at fixya, you say what type of water heater you have.
Gas tank , Electric tank, Tankless.

If you do not know, then look at unit.
Gas tank is about 2 feet in diameter and stands 4 to 5 feet tall. It has 2 water pipes on top, a 4" diameter galvanized pipe sticking out of top
Electric tank is same size, it has 2 water pipes on top, and a wire sticking out of top.
Tankless is a box that is attached to wall.

Look for label on side of water heater.
Write down all the information shown on label, and add a comment with that information.'
And then say what symptoms you noticed prior to water heater failure.

Cold water pressure poor in shower. Just had Rheem installed.


You might have clog in water lines.
If shower is only place where low pressure exists, then clog is probably at shower valve.
Disassemble valve and see if clog will flush out.
From there, you have to keep moving back along cold water line looking for pipe filled with sediment or elbow that has obstruction.

If pressure problem is bad at every cold tap, but doesn't affect Hot water, then clog is inside Cold line somewhere after water heater connects to cold line.
Buy a pressure gauge that connects to water hose.
Buy adapter that also fits pipe thread.
For example Brady BTG 100.
Test outdoor spigot for baseline pressure.
Open cold tap inside house and see how much pressure drops.
Close cold line and open hot tap and see how much pressure drops.

Next, move pressure gauge along cold water line.
Take apart pipes and inspect for obstruction at elbow or pipes filled with sediment.
Look for any place galvanized pipe connects to copper pipe, since this will be likely place for obstruction because of bi-metal corrosion.

How does rhe hot and cold water hook up on a 71-40d which is which top and bottom


Tanks are marked with Hot and Cold.
1) If water connections are on top of tank, look for red marking or word HOT that shows where hot water pipe connects. Look for blue marking or word COLD that shows cold water connection.
2) If water connections are on side of tank, cold water connects to bottom one, and hot connects to top.

3) If hot and cold are reversed, the tank will not work.
Pipes on top of tank: cold water enters tank and is sent to bottom of tank in a long tube called the dip tube. This means the cold is on the bottom since hot water rises to the top. The hot water exits top of tank.
Pipes on side of tank: You want cold water to enter bottom, so hot water naturally rises to the top outlet.
