kitchen mixer tap new install, flexi tail pipes too long

Post by finest1 » Sun Feb 25, 2018 6:16 pm

hi all,

my question is similar to this post:

fitting-kitchen-tap-t92907.html

but i have a slight different issue.

my copper pipes run from the old tap, half way is an isolating valve, it continues where it bends and carries on to the mains

the new replacement tap flexi tail connectors are too long. in fact, in runs down the entire length of the copper pipe, past the iso valve and ends just before the bend

now due to a very small leak, the elbow joint has decayed and i will need to remove it and replace it. i have already got a compression elbow

what do i do in this case where the flexi tails are too long.

also in regards to isolating valve will standard suffice or do i need a bore one?

many thanks in advance

finest! :hello2:

Can't you just cut the pipe further down below the iso value and attached new isolation valves lower down, (if still accessible ).
Flexible tap connectors can bend no issue.

I would use full bore iso valves in a kitchen tap, bathroom tap no (if on the mains) Depends on your water pressure of course

hi all

thanks for your response. I've attempted to attach some photos

first photo:

1) where the flexi hose screws into tap
2) isolation valve
3) elbow joint

second photo is more of a close up


hope this helps explain further.

Either:
1. Cut the copper pipe far down so the supplied hoses fit.
2. (Preferred) Get different flexi hoses- they come in variety of lengths- those look bloody massive! Then cut further up the copper, make for a neater install.

yeah, I been looking for shorter hose length. apparently 300m is the shortest. the one in the photo is 400mm, not sure if they come shorter than that. it may be the only option though, thinking about it, get the 300mm and work with it

thanks

johnny, no issue with water pressure, the ones on there already look like standard ISO valves. would you still advise bore?

the only ones i saw 150mm did not have the 10mm tap connector which screws into the actual tap. unless you can provide a link..

I don't see any issues with cutting the pipe and moving or adding in two new isolation valves. You mention you have to replace the elbow anyway. It will take 30mins max.

I like full bore in the kitchen but it narrows down to 10mm at the tap inlet anyway it will make practically no difference in flow rate. I would just get whatever is convenient.

It depends if you have a pipe cutter, ptfe tape, spare olives etc. Easiest was out is as others say, just replace with 150mm pipe. Looking at the picture I'd say 300mm won't have any major issues, just look rather clumsy. Best measure it
