Fitting an isolation valve

[hilti68]

Hello all,

Simple enough question.

I'm fitting a new bathroom but whoever fitted the existing bathroom didn't put any isolation valves on any of the supplies either to the bath, the basin or the toilet; so I'm doing this as a matter of course to make things easier in the future.

The toilet is fed by the usual 15mm pipe so I'm fitting a standard 15mm/15mm compression fitting. Does anyone know either hoe much pipe I need to remove, or how to work this out ?

Many thanks

Tony

TBH m8 i would not consider doing the bath, its awkward enough as it is under there. To determine the length of pipe to remove is simple.
Remove the two compression nuts on the iso valve. Once removed you will see a " shoulder" where the pipe eventually sits. Measure from that "shoulder" to the opposite "shoulder". Say its 20mm for example, thats how much pipe you need to remove for a nice snug fit .

Thanks for the reply WelshMan.

I hear what you're saying about the room under the bath. If it was staying in place I wouldn't even consider it, but its coming out anyway (will need a few weetabix that day ....its an old cast iron one !!)

The other end to the taps has an electric shower which is fitted into a tiled false wall,which is also being removed - so there'll be plenty of room when the new bath goes in.

....and when it comes time for that, there'll be a few more questions : new bath donated by friends who are having a new bathroom suite and kindly agreed to give us their virtually unused jacuzzi-bath. So the power supply for the electric shower will come in handy

You may be better using a isolating tap connector on the wc. This will fit direct to the ball valve inlet.
