Singular kitchen taps to a mixer tap

gazinio83

Is it worth getting a plumber in or is it a DIY job?

We currently have seperate hot and cold water pipes to seperate taps in the kitchen sink, we've got a new sink with mixer tap integrated so no need to cut or fill any holes etc I just need to change the 2 inputs to 1.

Any links to anywhere explaining how to do it easiest would be much appreciated.

Have you done any plumbing before? It sounds like you haven't.

Lots of instructional videos on YouTube

There will be one pipe to each tap at present. Whether you need to cut these pipes with a pipe cutter, or simply unbolt existing compression fittings will depend on what you have at the moment.

The mixer tap should have two "tails" - either as flexible braided hoses, or as solid pipes. Whether or not these will reach the existing pipework will depend on where you had to cut or unbolt the existing. You may need extra pipework to bridge the gap

If there's no isolation valves in the current pipework under the sink, you'll need to find other places to shut the water off. You should probably consider fitting them if they aren't there.

Whether or not it's DIY will, sort of, depend on you. How confident are you of doing this, apparently your first plumbing project, and getting it right first time, without leaks or mishaps? Should you maybe practice on something first, with some throwaway bits and pieces, or will you jump straight in?

You'll need a selection of appropriate tools, possibly extra pipework, and once you've bought these, you may find it was more economical to get the plumber in.

You may need;

Standard Pipe cutter / plumber's wrenches for pipework and fittings, depending on existing situation. To tighten standard compression fittings, you ideally need two wrenches - one to hold the body of the fitting, one to tighten the nut.
Compression fittings if appropriate
Olives for compression fittings, if using them (they're usually supplied separately)
Smaller wrench/spanner to fit tails to mixer tap
Isolation valves
Pipe fittings and pipe, maybe

Old rags to mop up spillages
Old bucket for carrying old drain trap with all its muck outside or to another sink
Knee pad(s) for kneeling on whilst your head is in the cupboard under the sink
Aspirin for when you bang your head on the cupboard (!)
