Taps

[Craftypig]

I have a mixer tap that has those flexible pipes attached to it, they can't be removed because they are captive in the actual body of the tap. They are 8mm, unfortunately the copper pipes that supply the water to the where the sink is going are 15mm is there an adapter that I can buy that will reduce from a 15mm feed pipe to the 8mm mixer tap pipe available anywhere?

Easily available at any Plumbers' Merchants Craftypig..............

Do you have a combi boiler, or a regular gravity system (with immersion cylinder)?
I have a reason for asking.

Combi..

Just checked the link builder, will they need any soldering doing on the copper 15mm pipe for the to be secure and leak free?

Good, that's OK. I asked because, with a gravity system, 8mm reduces the flow so much that the hot is often reduced to a trickle.

Combis provide hot at mains pressure, so no problem.

No soldering Crafters. The link shows a compression fitting.

Cut the pipe with a proper pipe cutter (no burrs)
Put the 15mm olive on......... then wrap a few turns of PTFE tape over the olive, and tighten the backnut up.

^^^ same for the 8mm

I should mention that the flexi pipes on the mixer tap have a nut on the end of each one, is this going to be an issue connecting them to the adapter in the link you provided?

[The Builder]

Ah......... a common problem. This usually works...........

Take off the 8mm backnut from the fitting. It's not needed.
The tap tail will have a rubber washer built in to it. Connect that directly to the fitting.

If, by some chance, it doesn't fit, come back again and we'll think about some sort of conversion adaptor.

Try it firat anyway :o)
