Outside tap

[raebhoop]

A plumber fitted an outside tap last year.T junction from a toilet straight through the wall with the fitting pictured.I can't get a drop out of it this year,and guess I should have turned it off with the bad winter...but didn't.
Will the fault be in the tap or this fitting?
I can't even remember if the fitting in the position pictured is on or off

PS...What's the grub screw for?

Thanks in advance...

That's closed that is!

Ignore the screw, that's a check valve

am no expert but shouldn't the black plastic thing be in line with the pipe for it to be on? It looks off to me.

 

[Breesey]

Quite!!

 

[raebhoop]

Ok...that's off...thanks.Still got no water on or off though...so will it be the tap or this fitting?

 

[Breesey]

Dunno!

Shut this one off again - disconnect and then try it.

If you get wet look at the tap - if not change this valve.

In any case don't forget to test the tap!

 

[raebhoop]

Ta muchly will do.

remove the phillips screw and make sure the valve head is actually turning, sometimes the plastic head moves without turning the valve

sometimes the o rings in the non return valves can come off slightly and stick them shut.

 

[raebhoop]

Thanks..I'll try these.

The tap probably of the type that contains the DCV. They are useless and always stick. Look at tap. is there a small hex nut towards the back?

can u post pic of which way the arrows facing

 

[raebhoop]

Can't see any arrows ...sorry.But if that's to do with the flow,it was working ok for months last year.
This is the tap...

Should that valve be the other way round?

it`s the valve thats knackered not the tap - the internal check valve is b`ggered by the water expanding back from the tap in the winter as it froze - Simples
