Tapping into existing plumbing

Many thanks, that's exactly the thing. Now all I need to do is find the Screwfix part number.

Hurrah!

usual mixture of 5* and 1* reviews

How well do those work? Tqhey always struck me as risking a bad seal or loose bits of pipe inside the pipe.

These look a better solution if you *need* to work on live pipes

And the Alladin avoids that issue

That is for wusses.

'ere:

wot has a firing pin and does steel, over 1" too if needed.

Copy/paste error?

Yes!

Expensive, but can save a lot of work in some circumstances, I expect.

But it's only an isolator - it doesn't provide the 'T' connection which the OP needs.

Forget it - turn the water off while you work and use a compression tee type washmac valve. Clean the pipe well before fitting.

Yes, use a proper T - I replaced the cutter type with a T compression and the flow and range from the hose pipe increased dramatically. Rather than a washing machine valve I used a full-bore ball valve and also a check valve. The ball valve has a T-handle for ease of use.

Yes, you fit an isolator without interrupting all water, so then you can fit a proper 3/4" compression tee W/M outlet, presumably the O/P has some reason for avoiding turning off the supply?

grin, Try useless heap of s*it tap system.

The only ones I've encountered on other peoples stuff tend to reduce the flow in the main pipe and if a main supply drench the fitter during the tightening up grin. Advice, do it on a warm summers day and put something waterproof over anything damageable. Of course it could have been the plumber at fault, not the tap...

'Emergency Plumber on Christmas Day Connectors'?

That's what happened to a former colleague, the punched-out copper disc got jammed somewhere and they couldn't turn the water off. Mind you, it was probably 35 years ago and they may have improved. The fittings, not the family.

That answers the question I had after watching the first one!

Thanks.

Interesting. I guess it's worth checking the pipe size carefully? ISTR that pipe sizes in France (at least) are different from here.

Why not an end feed? Cheaper and neater. And never leak later.

If you are fitting a drain valve to empty the whole system, then this should be one that allows good flow. That way there's a chance the water velocity will carry crud with it . The "pipe cutter" types will not do this for you.
