Quick question about part 2 float valve washers

[kp7722]

Afternoon all,

I've just had a phone call from the missus who said that water is pouring out of the overflow pipe and it's coming from the cold water tank in the loft. I got her to check and the ball was below the level of the water so it's clearly sticking (I only changed it 2-3 years ago).

I need to pick one up on my way home but (without looking) I can't remember what additional washers I need for it (I'm looking at the Pegler part 2 on the screwfix website). Can anyone help please - this'll save me from going home first to take a ganders which means I won't be able to fit it tonight.

Many thanks,
Paul.

I'd change the whole valve.

A standard Pegler High Pressure Part 2 ballvalve is an 858. Pegler had a contract with British Gas for Part 2 ballvalves, but lost it. The valves for that contract were labeled 758 and the pins are notorious for sticking and stopping the valve from opening and closing properly.

We bought umpteen thousand of them, and whilst the majority have been fitted and seem to be working fine there have been many dozen that have been returned to us.
As a result we've just sent a couple of thousand back to Pegler Yorkshire for credit.

It's possible you have a 758.

Thanks for your reply, mate.

I was actually intending (and did) replace the whole valve. I just couldn't remember what washers I needed for the connection to the feed, and if any were needed where it fixes to the tank. I had a couple of spare 1/2" fibre washers and the hole is reinforced by a metal plate, so all is sorted.

That's very interesting to hear what you have to say about the two different Peglers. The old one is definitely a Pegler, but it is slightly different to the new one - the body on the new one is actually slightly bigger (although the same length).

Luckily the overflow pipe did it's job well. Unfortunately the last time it didn't as the previous owners didn't actually cut the pipe long enough to stick out of the house, resulting in two very wet walls (internal and external).
