Sigh - what looks like another bodge job to fix... house is starting to wear me down.

Our outdoor tap has lost pressure. It is fed from a downstairs bathroom that has good pressure. Here's some pics -

That hosepipe (brilliant) goes directly to the tap outside. I can't see inside that hole.

What should be my first step for figuring this out?

Cheers
 
I've taken the outside tap off entirely and the pressure is still terrible. Is it likely to be where it's tapped into the pipe there?
 
If that was mine I'd, as a minimum, be replacing that self-cutting appliance tap with a normal inline version.

It doesn't look like it'd be particularly involved or expensive to replumb it completely.

Like an equal tee with a tap? I've not really touched plumbing so wasn't sure if it needs anything special

Edit: it looks from the pic like it goes from 10mm to 15mm back to 10mm, would that cause pressure issues?
 
They've used an appliance tap which the hose then connects to. Quite why they've inserted a section of copper and then used a self-cutting tap is a mystery.

If you were going to hard pipe it all the way to the outside tap I'd replace it with an equal tee and then an isolator tap.

If you don't want to get that involved then I'd replace it with an inline appliance tap such as https://www.screwfix.com/p/washing-machine-valve-tee-15mm-x-15mm-x/60723. You'd need to check the pipe sizes as you appear to have a mixture of 15mm and 22mm.
 
Ive got exactly the same issue with my outside tap which is the same setup basically.
The problem is the self cutter only makes an 8mm hole, it doesnt completely remove the copper either just bends it back, so its very easy for it to become clogged.

Only thing I need to find out is if the copper screw on bit is metric or imperial.

Great, I'll give the inline tap a shot. What you're saying does make sense. I don't think I'll hard pipe it just now, the bathroom will be getting an overhaul at some point so it can wait (3 bathrooms being done, spreading the cost :()

It would cost less than £30 at a guesss you just need to remove that self cutting rubbish and install a proper t instead.

You already have 2 push fittings either side so its almost impossible to balls anything up
 
Yep just to concur with others, it'll be that self cutting tap valve that is the issue. I had the exact same issue as it was all gunked up and corroded inside. I just removed the tap and put on an isolator valve and it's working perfectly now.

EDIT: Actually just had a look and I think the thread for the hose is 3/4" BSP (same as washing machine hoses).

But sounds like you might be going all out and replacing the hose, so this is probably not very helpful :D

I'm going to make a go at this today.

By the way chaps, the outdoor tap is over my decking. Should I, while im at it, put a drain beneath the tap so water doesnt pool on the wood?
