Capping off pipe work.

I want to remove this bidet as part of my bathroom refurb.

When it comes to capping off the pipes can i just cut the pipes down to below floor level and fit a couple of stop ends to the copper pipes and a solvent weld end cap to the waste?

Permanently? If so, yes to the waste but you should really trace the water pipes back and cap at the source. Dead legs can cause contamination of your water supply.

Yes permanently.

Not worked out exactly where they come from yet. Was hoping they were tee'd off the supply to the sink but they seem to go under the floor boards somwhere else.

Is it acceptable to use push fit stop ends once i trace back to the source? (depending on the arangment)

Last bathroom i did i had a hard time trying to solder up pipe work with residual water in the pipes or rather, trying to get the pipes dry enough. Dont fancy having to do it again in what will probably be a more confined space

I wouldn't use push fit stop ends in an inaccessible place. Too much risk of rodent damage followed by a large and unstoppable leak. Soldered is the way to go. If residual water is a problem, try a wet vacuum cleaner.

I never use push fit stop ends as a permanent fit, seen too many fail, if you cant get in to solder then use compression stop ends and as already advised cut away as much pipe as you can, dead legs can cause you problems

Capping off is Ideally no more than twice the diameter of the pipe, so 30mm if 15mm copper.

Not sure what you mean here...
Are you saying that distance that you cap off from the source should not be more than twice the dia of the pipe being capped?

Sorry, what is meant, as quoted in water regulations, if you’re calling off close to where it branches off, either remove the tee if practicable, or no more than twice the pipe diameter. Does this make any more sense? Not sure info it’s chnged though? This website states no more than 1.5 times it’s width: https://legionellacontrol.com/legionella/removing-dead-legs-water-pipes/

So i think the hot feed tees off the discharge pipe on to of the tank.

If this does not branch off to anything else would it be a case of just removing the tee reducer and fitting a straight reducer in place?
