My Reliance 606 electric water heater (2007) is leaking from the plastic collar around the anode rod on top of the unit. I've noticed some rust in the water when I tested the pressure relief valve.

Anode might be leaking ... or water heater is rusted out:

Vacuum valve leaking water

Question is unclear.
What is a vacuum valve?
You posted under electric water heater.
Water heaters are associated with TP or 'safety overflow' valve, water shut-off valve, tank drain valve, pressure-regulating valve, mixing valve and possibly a few other plumbing valves.
Vacuum valve implies that a compressor is creating pressure on one line while creating vacuum on another line. I don't know of a water heater that uses air compressor.

Water seems to be leaking from the top lid of my ge water heater

Make sure any water valves (Cold or Hot) for water heater are not leaking first. Gate valves may leak at the packing nut over time and drip on top of tank. If water is leaking from the top of the water heater itself the tank is corroded and water heater will need to be replaced.

My water heater is leaking cold water from the bottom. How do I fix it? its a Richmond miser. Model # 8v30-1

First shut off power then remove acess cover and carefully move insulation out of the way so you can see around elements.Check to see if leak is coming from around element.If it is determine what type of element you have. Either screw in or bolted in. Both have thick rubber gaskets that can be replaced by draing water heater and removing element then install new gasket and reinstall element.
To drain heater shut off valve on incoming cold water supply line ,make sure electric power is off. Connect drain hose to drain valve and put other end to floor drain or sump basin.You can open faucet on hot side near by to prevent vacumn and drain. If you have screw in type disconnect wires,marking them for reattachment,then use large open end wrench or pipe wrench on hex section of element and turn to left to remove. If you have bolt in element spray bolts with wd-40 or similar and carefully loosen bolts then disconnect wires and remove element.install new gasket and reverse to reinstall. I would recommend that you replace elements at this time if you are sure this was the source of the leak.
If you don't think it's leaking around elements then check fitting on both water lines to water heater to be sure they are not leaking and seeping down thru insulation and leaking out of the bottom of heater. Next check around drain valve for leak and if it's leaking you can try tightening it a little or replace it with 3/4 x2 brass nipple and 3/4 inch female iron pipe boiler drain. Use teflon tape or pipe joint compound on all threaded connections.
After you have eliminated all other sources for leak then it is probably the tank itself. If it is less then six years old the tank should still be covered under warrenty. Most warrenties will give you a new heater but installation will not be covered unless you have extended service coverage.
I hope this helps you some. Thank you

Slight water leak from plastic drain fitting on rheem fury 40 gal gas water heater

You can try to crack it open and get a little piece of crud out of there, I'm sure that is all it is, Just get a tray or something to catch the water, It should stop it, If it gets worse, turn the water off to the heater, then open the valve and hope the bigger piece of crud comes out. It is about all you can do, other than drain the whole thing and take the valve apart and replace the rubber in it. Check it out, Hope this helps.

Turned off the hot water to fix a leaking tap. now the tap has no hot or cold water and the hot water tank valve is leaking?

It sounds like two problems.
Problem 1) Clog inside faucet or clog inside pipes at faucet
Remove supply tubes leading to faucet and see if problem is inside pipes or inside faucet.
My bet is clog inside faucet.

If you have galvanized pipe that meets copper pipe, this can be trouble spot.

Problem 2) Water heater leak ... you say tank valve is leaking? Is that cold-water shut-off valve? Or tank drain valve? Or TP valve?

If cold water shut-off is leaking, then replace shut off.

If tank drain valve is leaking, then check if plastic valve is cracked. If drain valve is cracked, then replace with a brass valve from Home Depot. If plastic valve breaks off, then use hammer and screwdriver to gently chip out the broken plastic valve. New valve threads need teflon tape to seal pipe. If valve is just dripping, then put garden-hose cap over end of valve and screw down tight.

If TP valve is leaking, then replace with same temperature and pressure rating. New TP valve threads need teflon tape to seal pipe.

Problem 3) If pressure is low all over house:
Buy pressure gauge at hardware store that screws onto hose connection.

Test pressure on outdoor spigot.
Open faucet and check if pressure drops. This says if problem is inside pipes that enter house.

Test pressure on water heater drain valve.
This says if pressure problem is before -or- after water heater.

If problem is before the water heater, then shut-off valve located on cold water line is suspect.
If problem is after water heater, it could be in hot water outflow pipe on top of water heater, or a nearby elbow.
Remove hot water line leading from water heater and check pressure. This says if problem is where hot water leaves tank.
Read articles above about clogs inside water lines.

Leaking pressure relief valve

what is the water pressure on the cold side? You may need to install a pressure reducing valve at the water heater inlet to reduce inlet pressure and keep pop off valve from opening when not needed.

Temperature & pressure relieve valve leaking

Hi,
Once in a while flicking the little handle will reseat the valve or release whatever dirt is under it. Usually not...
Your best bet is to replace it.
Turn off your hot water heater and drain the water down past the valve. It jusr screws out and the new one will screw back in.
You can find a new valve at any hardware, HomeDepot or Lowe's they are not exspensive at at.

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

I have water pouring out of a pipe outside that is coming from my hot water heater.there is a cap missing but i'm afraid if i put the cap on the pipes will burst.what could be the problem?the water heater...

That pipe is connected to something called the T&P (temperature and pressure) relief valve. The pipe that connects to the valve should be run to a drain line so that the water goes somewhere other than all over the floor, but often it just ends a couple of feet from the valve. It's possible the valve has opened because the pressure in the tank is over its limit, but more likely it's the valve's fault. If the new heater was supplied without a T&P, the installer may have used the one from your old heater. Over time the spring inside the valve weakens. Then it can't hold the pressure from the new heater properly. A new valve is under $10 at home improvement stores or larger hardware stores. It just screws into the water heater, so it's simple to replace it if you have a pipe wrench. Turn off the water into the heater and remove the old valve. Use Teflon tape or pipe dope on the threads of the new valve (the store will sell that too), tighten it into the heater, then turn the water back on. That should end your leak. If it doesn't and the T&P valve still opens, you'll need to have a plumber check the water pressure in your home.

If it is the threads leaking., you can #1 shut the water heater down or turn it to pilot. #2 carefully loosen the top connector to the valve, #3 remove valve #4 apply teflon tape, usually 3 raps nO more than 5 to the male threads #5 carefully reassemble. turn from pilot to normal. if the water heater continues to leak it is possible that you observed leakage from the valve but the tank itself needs replaced. hope this helps.

Yeah, it’s not coming from the threads. Its coming from around the outside of the female thread piece, where that female thread piece itself imbeds into the tank.

SOURCE: Hot water heater leaking at the top valvue

I believe the problem you had with the pop off valve is a one time thing since you said you just installed the water h eater

The pop off valve is a pressure relief valve that is activated by build up in the tank from excessive pressure either through too much heat or pressure which works by pressing aginst a spring loaded valve

If you go to the whater heater and look at the valve ther is a handle on it take your hand (stand clear of valve opening) and slowly pull it you will see water start to come out

More than likely a new valve could have had a piece of debris in it or was partially open
re
If the heater was overheating the valve would stay open and you would see extremly hot water rushing out

I do not recommend that you replace the valve unless it continues

Good luck to you

SOURCE: hot water heater is leaking and making noise

Hit the disconnect and call a plumber. Sounds like your heating element or elements have gone bad and need to be replaced. also shut off the water. This is repairable, but it is HIGHLY recommened to have someone with expeirence in this kinda of problem fix it since you are messing with water and electricity. The repair should be no more then 200 dollars

SOURCE: Hot water tank leak

drain valve must have already been leaking, that's why someone put the cap on. It's ok to cap the drain but never the pressure/temp relief. If the water is coming out of the drain (not around it) you could either replace the cap or the drain valve to stop the leak - otherwise it's time for a new water heater.

SOURCE: Drain Valve on bottom of water heater drips when Water IN turned

If the hot water heater is gas be sure it's turned off same if it's electric so you don't burn out theelements in the tank, I would advise you to buy some plumbers putty and pull the drain scre out and put putty in it then reinstall the screw. all the ones I looked at I could not tell by looking to see where the drain was and if it has like a hose bib on it or not. also pull the screw all theway out and see if you got some sand in the valve and if so use some compressed air in a can to blow the stuff out of the seating area of the screw. Hope this is helpful would be nice to have a picture of the drain.
