High Pressure or Low Pressure?

[raceboy]

Currently got a dripping float valve in my loft cold water tank, doesn't look like too nasty a job to replace and at £6 for a new one it's not going to break the bank, but......

Do I need a low pressure, or high pressure valve?

Looking at them online I can't see a difference outwardly to each one or the one currently fitted?

If it's mains fed then get a high pressure valve. They all look the same, but differ internally in the restrictor size.

Ok....fastly running out of my plumbing knowledge.....

Where the water comes from I have no idea.
It's a 'standard' new(ish) build, the pipe it's connected to disappears off across the loft space and looks like it might go down into the airing cupboard, if I get it wrong will anything bad happen?

It will be a mains fed tank so turn off the main stopcock before attempting the changing of the valve, or if you are that unsure then get a plumber in.
!5 mins work plus a cuppa.

There's a stop cock next to the float valve, that one appears to stop the flow through the valve, I think the biggest problem is going to be finding enough big spanners!
So high pressure part 2 float valve here we come........
What's the worst that can happen....

You could slip and fall into the tank.

Put a new fibre washer into the tap connector when replacing the valve.

Wear Speedos just in case.
