Water leaking from boiler..







I drained out about 5 gallons of water each time it did this but somehow it refilled past the 20psi?

Any thoughts....
Thanks in advanced

Ayuh,... My guess is the pressure tank is full of water, instead of air...

The pressure reducing valve may be bad or you have a fast fill bypass valve leaking past the stop. Could also be the tank as suggested.

Ayuh,... That's the tank that should be about 1/2 full of Air,...
There's already Too much water...

I'd update it to a bladder tank myself...

I read that wrong, so I need to drain all the water out of that tank?
And far as bladder tank go any special size I need?

Ayuh,... Correct,... There needs to be a head of air in the tank,...
Water don't compress, air does...

Sizing depends on system size, 'n configuration...

Did you ever check out the water feed valve and by-pass that was mentioned in a previous post?

Yes but there should be an air water barrier of air can pass dirrectly into solution and when the system is off , the air will gather at the highest point, thus air locking your system. Get rid of the tank and put in a gas charged exspansion tank. Hang with scrader port hanging down for easy leak detection. Ball valve before tank for easy swap out. The only problem with you going to have is you'll have to drain system down to the level of installation. You can put them any where. If you have a take off on the to of the supply header, thats a good spot and its rigid and usualy out of the way.

As you can see there's only one pipe coming out of the tank & on the opposite side of the tank it's a bolt.

Well the bolt is a pipe plug . That shoul at least be a boiler spigot. Looks like yiu have change you pt vavle a few times. Check the pressure rating for the pt. Ill bet yoy its 30 psi. The boiler pressure should reach around 20 psi which should be the automatic fill pressure .

Secondly the pt valve needs to have a pipe to the floor i beleve within 8 inches per code , not sure of the distance but yoy need one

It might be a few weeks before I can get A Bladder Tank, is putting a bladder tank in a DIY?
Is there anyway I can pump more water in the tank for now?

This problem started when I drained the system halfway to install a valve on one of my radiators.
