Brass float valve, ancient one high pressure, 1/2" I think

[spendorman]

Going out into the garden this morning to feed monster cat, it was very strange, it seemed to be raining on me, but it wasn't raining!

I looked up and saw that water was dripping out of a pipe at roof level. An overflow pipe.

Went into the loft and found that the heating header tank was overflowing.

Turned off the rising main, with difficulty took the very old (perhaps 1950's) float valve out.

Piston rubber washer was worn.

Could not find a replacement, so reversed it (this was my mistake, I should have measured the diameter first).

Put valve back, all OK.

I want to order new rubber piston washers, anyone know the diameter?

Thanks.

they come in all different sizes alas.

is it the o ring flat type or the full solid one?

Hi Grant, thanks for the reply.

My second mistake is calling it a washer, it's in fact a flat disc, no hole in the centre.

Over the years I've done a few of these valves, usually large disc for low pressure valve, smaller disc for high pressure valve. Normally just these two sizes.

ah then its the solid stops... try this link.. https://www.ebay.co.uk/itm/WATER-CIS...frcectupt=true

sure if u asked they could supply you with a few different sizes. there are different shaped one too alas.

lol. yes. was looking at that listing before posting here, hence the question of size!

i did one for my mothers years ago. it was pretty old and if memory serves it was an inch and a quarter dia. but as you see from his listing there are lots of different ones and styles. ypurs is obviously a much smaller one so probably 13 or 14 mm.

Thanks Grant it's probably 3/8" or 1/2" diameter as it's so old.

I'm going into the loft shortly to check for any leaks. I have a vague recollection that there are a couple of spare float valves there, if so I'll measure them. It'd be my luck that they are low pressure ones.

Noticed in the loft, cardboard boxes for my Quad stuff those for the ESL 57's and 63's are massive.

Well, just looked at the repair, no apparent leaks, found the spare complete brass float valve, yes it's the wrong one, later type diaphragm type low pressure, probably bought for toilet cistern.

Also noticed in the loft, two Garrard SP25's, one a Mk2 fitted with a Audio Technica AT66, the other Mk3 with Goldring G800, and a Garrard AT6 fitted with a Decca Deram. Be nice to get these going one day.
