Help with an outside tap and poor pressure

[jorton]

Hi, First timer posting on here but I need some advice.

I've tried to use the garden tap for the first time this year(turned off over winter) and the water flow out of the tap really poor compared to last year. Our garden tap runs from the pipes under the kitchen sink. We had a new mixer tap installed in October and the water flow out of the cold tap is brillaint as to the hot tap.

However the ouside tap and associated pipe is attached to the cold water pipe that leads to the mixer tap but as I've said there is not a lot of water flowing out.

At the same time as the mixer install we had a power shower fitted in the upsairs bathroom this is driven via our combi boiler downsiars. We have decent pressure within the boiler and the shower works fine.

So why does the garden tap run poor even though it is linked to these other taps. Ive tried shutting off the supply to the mixer tap and the washing machine using the various valves in the pipes but still no joy.

Please help

is the shut off valve to the outside tap fully open? Has the outside tap got a non-return valve in it and this has stuck?

Isolate water to outside tap, take off tap head undo guts and free the washer that will be stuck (ie come off end of spindle) Turn it over or fit a new one then replace.

O ring on non return will have pushed out and jammed the check valve after frost. Fixed many a hose tap with this problem.

Power showers and combis dont mix. Are you sure it is a power shower?
