Reposition Old Bath

[mortarbo]

I've a 1972 built house. We bought it recently. Original Taps (to its Bäth attached) are as the image shown. Not sure of size of 1972 pipework. Pipes shown.

Want to be able to raise height of bath so extend pipe for tap attachment.
Theres no isolation an also i thought of using one as shown green box?. Do i use flexi pipe also?.
Because of 1972 sizes and the 18mm approx diam (which seems to reduce?) not sure what to do. Not a plumbing guy but more than happy to give it a go with valued advice. Hopefully no soldering involved (use olives etc?)

THANKYOU.. Pic attached

The part that joins pipe to tap is called a tap connector , The thread would be 3/4 bsp ( where it joins/ screws onto the tap ). This has been soldered onto the supply pipe . supply pipe maybe 3/4 inch or 22mm. How much do you need to raise the bath / extend pipework ? For isolation valves fit full bore , (lever operated if you have the space). You can buy flexible hose tap connectors ,some with built in isolators ,but they are restrictive to flow so I wouldn't recommend them ,particularly if your water is gravity fed.

Ref question...

Need to raise bath around minimum 200mm

As there was a Combi Boiler fitted recently, the upstairs bath doesnt take cold supply from removed loft tank but now comes from mains supply. Hot supply comes from combi; also upstairs. Not sure of the importance of this in your comment if you could advise me (the novice) please. Thanks.

Rigid pipework is better than flexible hoses. They are biggest cause of floods in homes and as you have a combi they are under higher pressure all the time, that said, many use them (including me when they are supplied) so your call.

If you do use them, get ones without isolators and fit separate full-bore isolators with lever or butterfly handles rather than the screw slot ones which are prone to leak when actuated.

I would...
Isolate cold feed to property and open taps upstairs and downstairs to drain pipes.
Cut copper pipes to bath at a convenient location so that you have room for 22mm butterfly isolators and room above them for either flexi hoses or rigid pipework to connect to Bath tap tails.
Fit butterfly isolators onto the pipes and make sure they're off.
Put tape over the open ends of the isolators to prevent debris getting into them.
Reinstate the water supplies and bleed air out at upper taps.
You can then do what you need to do with the bathroom.
When done, either get flexi hoses to connect to taps and isolators (either compression hoses, using a short bit of copper between isolator and hose, or hose with a cap that screws onto a flat faced adaptor to the isolators) or use rigid pipework with compression tap connectors to the bath taps.

Or use rigid (copper pipework) and a bath tap connector...

Great advice dilalio.. so grateful.. thx

Worth checking if the supply pipework is 3/4" or 22mm - or even have a few 3/4" olives to hand before cutting pipework.
