Hi,

I am looking to get a new kitchen sink and tap fitted. I’ve started to think that maybe I will deal with the worktop myself and get a plumber in to do something with the water before I start on the worktop and sink.

My system has a cold water tank in the roof and a hot water tank which is heated by a boiler. All the taps are gravity feed from the cold water tank in the roof, except the kitchen cold water supply which is direct from the mains. The house is 2-story and the cold water tank is in the roof above the second story. I don’t know what the mains pressure is but water comes out of the kitchen tap at a really good rate, much faster than the hot water gravity fed tap. I don’t know how the boiler is fed but I think it is from the cold-water tank. There are no isolation valves on the hot and cold feeds to the kitchen taps.

What I am thinking is that I should get a plumber in to drain the system, fit isolation valves to the hot and cold feeds to the tap, and fit the new tap to the old sink. The new tap will have flexi tails (not compression fittings).

Then at a later date when I have a new sink and worktop ready to fit I can use the isolation valves to allow me to remove the kitchen tap without affecting the water in the rest of the house. I can then take out the tap and the old sink and fit a new worktop and sink myself. I can do the waste connection myself and re-connect the tap myself.

Does this seem like a reasonable way to go?

Is the kind of fitting on a flexihose (tightening a nut against a rubber washer) suitable for direct-to-mains connection (mine seems to be quite a high pressure)?

Thanks for reading, any comments welcome. Pictures attached.

You’ll probably have flexi hoses on your new taps?

Edit. You do.

So you can install inline valves on the feed pipes and just check if you need a tap connector end or if the flexi can go directly to the inline valve.
