Help! Bottom-Entry Valve to short to connect to new isolating valve.

[Steve]

Hi All

I have replaced my toilets Bottom Entry valve and replaced the isolating service valve on the existing pipe. Problem I have is the bottom entry valve thread is just to short to reach the isolating valve for me to screw it in. (Picture attached)

Any tips on resolving this would be much appreciated.

Cheers

Fit a normal isolator further down and use a small section of copper with a new tap connector , you can buy a speedfit type push fit if you dont solder

Does the pipe lift up at all ??

If it doesn't you have two options

One : fit a coupling lower down and add a new piece of pipe

Two : 1/2 female iron with a rubber washer

Both of these will require a new fibre washer on the service valve

Cheers for the help. The picture is with the pipe lifted up.

So if i get a 1/2 female iron can i just connect one end straight to the plastic thread and other end straight into the isolating valve thats already on? (inserting a new washer for both connections)

Or if you buy a full bore isolator that is the type that has a fair space between the pipe stop distance, then that might make up the difference for you. I think the gain would be about 20 - 25mm maybe

You could do that, but trouble is not ideal as you will have a sharp tapered edge hitting the washer in your isolating valve. Really better with a flat surface against the washer

Yes normally rubber washer for inside the female iron and red fibre washers for the valve

File it flat takes 1 minute to do but ops choice

Is that file the female iron flat?

Yes, Shaun means file the brass tapered end of the brass female iron - the part where you normally put a copper pipe and nut and olive.

Cheers guys.

Would it make any difference connecting the isolating service valve to the plastic inlet first then trying to push the pipe up to connect to the bottom of the isolating valve with a little more force?

 

[townfanjon]

Hell no , never force anything thats plastic , unless you want to flood your house

put it on the inlet valve first (ball / float valve)

then tighten onto service valve while holding the female iron to stop it tightening more onto the plastic threads

yes where the nut and olive are just to flatten out the edge so isnt sharp (wont take much)

Thanks.

Just to make sure is this the 1/2 female iron I need for this?

 

[ShaunCorbs]

thats the cookie

dont forget your washers tho

one rubber one and one fibre one

Cheers mate. Will give it a go. Wish me luck

all good advise above. I would personally cut the pipe and just solder a coupler into the pipework. It does not look like you need that much play to be honest.

Thanks for all the advice. Another idea I had was to use a flexible tap connector with a valve instead. Would that be a workable option?
