Overflow in main water tank

[MacMurphy]

I had a brass equilibreum valve once, very expensive, I particularly remember the makers said you had to use a 6-inch copper float. I presume it takes a lot of leverage to shut it off securely.

Don't know why, the more modern plastic equilibreums have a tiny float.

It might help to bend the arm so the float sits lower in the tank and would be fully submerged before it overflowed.


AFAIK they are not widely used, I seem to remember they were popular on farm livestock trough supplies where pressure can vary a lot.

Thanks. I have bent the arm, but it still doesn't shut off. Will get the float you suggest and try that.

I live in a rural village ... maybe the pressure varies a lot ... similar to the livestock troughs you mentioned.

Cheers

Ok stupid question time.

You have fitted a high pressure ballvalve and not a low pressure.

Very observant JohnD are you making a point or

 

[JohnD]

the brass one is supposed to cope with varying pressures

My question said, "you have fitted high pressure ballvalve" meaning if he has low pressure ones it could be why the OP is having problems.

Equilibrium valves are an idea for a fix, to a problem that is un-real and shouldn't be happening, if the right valves were fitted.

Which Dorset village are you in?

Presumably when the ball valve came you fitted the seat insert with the SMALLEST hole in it ?

Brass ones don't have two, they come high or low.

I have fitted 4 new brass equilibrium ball valves in the past year.

Who was it who defined insanity as doing the same thing over and over again and expecting different results?

Pressure reducing valve...around £20 Peglers Brass equib. valve = £70 3 pages and counting Are all the PHd gas fitters out of work and posting here My shrink says the repeition thing is OCD . My shrink says OCD I say, OCD

I *believe* it is a high pressure valve .... its what the plumbers said was needed!

It came as a complete unit .... screw the old one off, screw the new one on.

You got me! It was the quickest way to cure the problem each time - even if it was only a temporary fix. Been so busy with other stuff, I didn't have time to do anything else. Now finally trying to get a bit of sanity and looking for a longer cure.

But sure - been insane the last couple of years.



Will try to get replacement washers and the 6" copper ball someone recommended earlier on.

That is not a good plan you should change the whole valve.

You should also check the nozzle is only a couple of mm and not 5-6mm.

let me know if you're chucking the old valves out
