essex flange

[dexion]

hi

im replumbing the way the water flows to the shower pump as its installed incorrectly. the cold supply to the cylinder has a tee in it to supply the cold input to the pump which causes lower pressure at the hot pump supply.

the problem is that the cold storage tank is 'built into the house' and there is no potential to get a fitting onto it other than an essex flange which i can only drill the hole for vertically into the bottom of the tank. will i find the inside of the tank corroded to the point where i cant seal it and just have one big mess on my hands?

the cold tank has prob been in there 30 years.

Whaqt type off tank is it Copper/Fibreglass/Galvanised steel or plastic. Is there no access to any of the sides at all. How do u gain acess to the float valve.?

 

[dexion]

its a galvanised water tank, why do i need to worry about the float valve?

not enough space at the sides to get a drill in

Replace the tank, at 30 years old its ready to start leaking anyway.

Mine leaked when I was away over Christmas, fortunately it leaked through the light fitting into the basin below!

If you have a galvanised tank, I assume you mean hot water tank, then run your hand around the sides and look for a return tapping, about a 1/3rd down.

Ideal for a pump if you can find one.

As for fitting and essex flange I really don't advice you try. Certainly I would only do it at your risk, and with the understanding you could need a new tank.

wrong assumption

wrong assumption

Ooooooops

I still would do it though, new tank is the only way to go.

Definately risky to drill the bottom of an old galvy tank, very likely the bottom will fall apart once disturbed. If it is in perfect condition you could get away with it.

I understand that it will be a major operation to chane the tank because of access / location. In the end you will have to so have a good long lok at doing the full job now with a new one complient with water regs (still referred to as a bylaw kit, but not strictly true).
