Identify red head valve

Dan Gilbrook · Feb 26, 2019

Hello.
Can someone confirm what this valve with the red head is please?

Please do not touch it if it is what I think it is.
I think it is a pressure valve hence don`t touch it yet and wait awhile. The isolation valve under it is normally full open or full closed. Why are you asking, having problems somewhere?

Someone needs one changing. I've never dealt with them. The check valve under is broken to. Not had much experience with these.

Can you confirm this is a pressure reducing valve right?

I can't mate, not the sort of thing that I get involved in.
Others will be able to say.

Red top valve in first picture is an Anti vacuum valve,
Lets air in if the pressure goes below zero, mainly to stop the cylinder collapsing.

They hold closed under pressure, but quite often leak.

Brilliant, that's what I was looking at online. Can you confirm the bottom one please?

Pressure regulating valve, probably SYR made by or part of Relliance Water

Awesome! Thanks a lot

Snow head has covered all your questions but if your looking for spares I find advanced water quite useful for those.

Just make sure you're registered (g3) to work on the components if connected to unvented cylinder system before diving in.
