Rheemglas Fury DV leaking?

Our Rheemglas Fury DV (model #21DV50) started leaking from the side pipe. It looks like it is an overflow pipe, but I didn't notice it ever leaking before. Is this normal?

    I have a Whirlpool Lifetime 50-gallon electric water heater that recently started leaking at the safety pressure relief valve. I replaced the valve, and lowered the t'stat setting, but the leak is still there. I have noticed that it leaks more when the water is used and it doesn't matter whether the hot water is used or the cold. I don't know whether the local utility has installed a dual check valve or not. Will an expansion tank resolve this problem?

    The heater was made in 12/2010 and it does not get as hot as I want it to. I want to turn the thermostat up, but it says I need to unplug it first. If I do, is there a procedure for restarting it, or do I just unplug it and plug it back in? Thank you!

Rachel,

I don't know if you have resolved your issue by changing the T&P relief valve. However, if you have replaced it and it appears to have resolved the problem ... it will most likely be only a temporary resolve. And what has happened, it that the water that was being relieved via the T&P valve is now unknowingly leaking / being relieved by a toilet or some other means.

The reason of the leak in the first place is that the most likely the water purveyor has recently installed a DCV (dual check valve) at or within the water meter location. Not knowing where you live, but we are in NC and these DVC's are being installed all over the country.

Basically, your home's plumbing system used to be an "open system" and not it is a "closed system". In earlier times, when the water heater cycled it heated the water, which cause the volume to thermally expand ... and the water was pushed backwards through the meter and it did not allow the water pressures to build. However, with the DCV installed ... now when the water heater cycles and expands water, with no place for the excess water volume to migrate, it now causes a hydraulic effect within the closed system ... which causes the water pressure to become elevated, ultiamtely being relieved at the T&P ...

Here are a couple of links from Watts ....that will help.

Locally, we have been on the Cross Connection / Dual Check Valve crusade since early in 1991. We concur that the check valves warrant installation. However the Buidling / Plumbing Codes are not up to speed with truly what is going and how much damage to personal property is occurring with failed water lines ... both inside the home and outside.

Best, Gary H.

It it the relief valve. It is not normal to have water leaking out of it. The relief valve a a safety device which prevents the water heater from building excess pressure IF the control systems on the water heater fail. That little valve on the side is one of the most important safety devices in your home.

The relief valve needs to be replaced. Check under the referral section of Fixya.com for a qualified contractor in your area.

Please rate this response and best of luck, Phil

I have a Park Model RV with a Rheemglas Fury model 81VP205 with no bottom drain. How do I drain the water heater to winterize for the cold Northern Winters?


Make sure it's off (hydro) and open drain at cold line going in bottom wherever you find a drain (usually close to it) going down through floor and outside under trailer. Follow cold line back until you see a line "T" and one line going down under trailer, and open it up underneath. Then open pressure relief valve at top of tank to allow for faster draining .

My Rheemglas fury 21DV50 hot water heater pilot goes out about every 2 days for the last week and 1/2. It will light and I'll be able to have hot showers but doesn't last more than about 2 days. Is it the...


It could be a thermocouple but first take the whole pilot assembly out and disassemble it. Clean it very good (compressed air is ok) especially the orifice inside the pilot horn. You may just have a weak pilot. If the flame is in good contact with the thermocouple and problem still exist, then change the thermocouple. I believe in doing the free things first.

Water discoloration. Rhreem serial rh0909ff00279 date 9/2003 model 8v520c 50 gal electric rheemglas fury. prolem occures when we use hot water. tried fixing...backwashed, drained water out completely...


Brown discoloration is evidence of a rusting or corroded steel pipe somewhere in you plumbing system. Trace the water lines back from the faucet and replace all the steel pipe.
White discoloration is minerals that separate out when the water is heated.
You can change the Anode Rod and it should help. It is not an instant fix, the rod will take a week or two to do its job.
If your water heater is still under warranty, call Rheem, they may replace the water heater free.

I have a Rheem glas fury model 22-40 gas water - leaking


Dear Hank McNeal; I have successfully used a "boiler plug" to seal a water heater tank leak in 2007. It was a 100 gallon electric commercial hotel unit. To this day it's still in use. It depends where the leak is located....Predrilling the leak is necessary to be sure the plug will ernguage it's threads into good material... Start as small as possible, then use the best suited plug. they come in an assortment of sizes. rheem-glas-fury-model-22-40-gas-water-qbzdprdp3yetvbzozs4dsujq-4-0.jpg
