Hot water press relief valve

[John C Marsh Jr]

My standard issue hot water tank pressure relief valve leaks, only one year old.   Can this be replaced with a standard pressure relief valve from the hardware store or is it special RV issue?

 

thank you

It is a standard type, but check the pressure and temp rating on it to be sure. A Camco tool works great for removal, and you can also use it in your home water heater.

There may be nothing wrong with yours, remove it and soak it in vinegar for a couple hours with the lever open to remove hard deposits. That might cure the slow drip.

John, another water heater question, does your hot water electrode corrode over a period of time like your sacrifice rod does. Just wondering if it needs to be removed an checked, all I know is they either work, or they don't. Thanks,

As with any heating element - they do go bad over time.  However they are not "sacrificial" like the anode rod is.

I've never removed mine on any of the campers I've owned over the past 25 years and none ever failed to work.
