Suburban Hot Water Heater

Thanks John
Do I need a plumber to replace the relief valve?
Or can a mature (old) fart do it?
PeteM

Shouldnt be a problem for a half way compotent old fart to handle....... just make sure you replace with a valve of the same/correct rating. Take the 'old' valve to the plumbing shop as a sample.

hi petem
as advised make sure you replace the pres-rel -valve with one of the same pressure relief ratings or your water heater will explode
my irish neighbour thought he was saving himself some money and replaced his solar heater relief valve with one that was not the correct pressure and when he turned on the elect booster the tank burst flooding the roof and causing water to penetrate his ceiling
i didnt really feel sorry for him as he is the biggest scrooge i have ever me
cheers

As Darryl says, it is perfectly normal due to expansion of the water and all heaters do it.
If it is dripping in an inconvenient location, extend the pipe with some hose to a more appropriate location but do not allow the relief pipe to become blocked.

Thank you all. I will have a go at fixing it today & if necessary buy the part required
Many thanks

You don't need any new parts.
What you heater is doing is entirely normal as mentioned above.
Replacing the heater PRV WILL NOT stop the water drip. They all have to pressure release above the preset. Everyone heaters are doing the same thing.

You should already know this by using your powers of observation.
New parts will do exactly the same thing and you will have done your money too.

Not so, my does not weep when heated.

John

NOT when heatED but it has to when heatING.

John, if the relief valve does not weep when heatING, then either the non-return valve in the cold feed line is inoperative or the installation is incorrect. The expanding water has to go somewhere.

Thank you all.
I will leave alone if releasing the valve regularly doesn't fix it
