Hi all,

Occasionally, there is no water from the Outdoor tap.

Replaced tap. No difference. Took tap off. Check valves work, washer in place, unscrewed head from the body and tap all clear. Tap mechanics seem to work when off the wall. Sometimes no flow from exposed pipe with tap off the wall.

Peglar double check isolator valve indoors turns ok. Took plastic handle off and turned the spindle with grips on and off. Still the sporadic loss of water occurs.

Had kitchen replaced 2 years ago, but problem only started 1 year ago.

Is it the isolator valve that is likely to be faulty do you think? To replace valve would mean cutting the back of sink cupboard out and my back is painful so would rather not.

Any other thoughts before I call my trusted plumber in to look?

Thanks.

I take it that it is just the garden tap affected, or do you not try other outlets when this fault occurs?

thanks CBW,

the kitchen tap works all the time But didn’t test any other outlets. Maybe a coincidence, but occasionally outdo tap will start flowing if sink tap is turned on and off a few times.

Thanks Chris.

I had flushed the pipe work through in the past with the tap taken off but sometimes no water runs even with the tap off the wall.

Do you think it’s worth me putting a wet / dry vac on the outdoor pipe work with the tap taken off the wall?

Was the outside tap originally fitted using a self cutting isolation valve into the supply pipework by any chance ?
If not the check valve is suspect

tnx Terryplumb. No self cutting involved. Valve is compression fitting. I will ask our friendly plumber to replace the valve. disappointed in Peglar if it is the valve as I asked for a Peglar valve as this brand was recommended on here. Maybe a rogue valve
