Another garden tap question. Tap is siezed and can't be drained down, still ok to isolate?

[Mmcgar]

Hi all

I realise that garden tap questions are all the range this time of year but I thought I'd ask anyway.

I have just isolated mine under the sink but can get the actual tap to open to drain down. essentially I know have a volume of water in the pipework that is isolated at both sides, is there any issue with this?

It's the plastic hose type pipe that's been used (was one of those cheap, self cutting garden tap kits)

Edit: managed to unseize the tap. However noneater coming out at all when opening. Assume maybe frozen up inside the tap (been covered in a tap jacket for last few weeks and looks ok in terms of no frost etc on it).
Tried pouring warm water over the tap but no flow. Have currently left tap and internal isolator closed so same issue as before essentially)

Thanks

Water is held in the pipe and tap by vaccum once isolated. There should ideally be a drain cock . Undoing the union / joint to the tap would allow water to drain.

Thanks for that. Above is what I'm working with, anything here as a drain point?

If the white handled valve is the supply to tap ,close it. Then undo the nut at the bottom where the feed to outside tap goes. With outside tap open( turned on) , water will drain ,have a bowl or a towel handy where you undo the nut.

Thanks mate.

Yeah white handle is supply to tap.
Out of interest, have you ever used these self cutting/self sealing kits before? I've been pretty wary since day 1 of interfering with it too much in case it causes a leak.

Also, any idea what the screw on the side is? I wondered if it was to allow air in

Screw on side is for the non return valve ,leave that alone.
I don't fit those DIY efforts . Anything that cuts into a copper pipe and leaves a bit of cut copper inside the pipe is hardly inspiring !
You could of course undo the jubilee clip and pull off the hose ,show us a pic of tap outside.

Yeah that was my fear with this, that it's basically an easy but not very robust method of fitting a tap. In fairness it was my wifes hairbrained scheme.

Tap is below. Just in case there is any ice in the pipework (been -8 here for a few days) I've left the white handle isolated and the tap very slightly open. Once we've thawed out a bit I'll open the fitting to allow to drain, will likely wait till after Xmas though just in case anything goes wrong and I need a plumber, any particular issue with doing this?

Thanks for the comments btw

Also I should add that the tap does normally have a frost cover on it

Leaving the white tap closed and garden tap open should be fine.
