Fitting isolation valves

FOX_HOUND

I would like to fit some isolating valves to the shower and bath/sink.

At present I have to shut the entire house off if any work needs doing.

Having no plumbing experience whatsoever I was thinking of using push fit. For those that have used these type of fittings do you know of any pitfalls I should be aware of?

Are there any special tools required?

Its probably doing work for nothing but hey ho.

Thanks.

No tools required, dead simple.

You will need a removal tool should you wish to take them off but obviously dont need that for a while.

I would just do it next time you have the water shut down.

Even if you go down the compression route its still pretty simple.

No / few pitfalls that im aware of.

how to do it.
using plastic speedfit types is very similar.

If the pipe has been painted then make sure that you remove it before fitting push-fits or compression fittings.

don't use a hacksaw to cut the pipe it will leave burrs & damage the o ring seal, always use a pipeslice

Does a pipeslice leave burrs?

If so do you use a deburring tool sandpaper?

normally the pipeslice cuts a perfect cut.
occasionally you may get a slight burr. just use a rat file to clean it up a tad.

OP : if you use push fit, play it safe - make sure you de-burr the pipe (with wire wool or a file, or similar) and be sure that you seat the pipe fully into the fitting. Most failure of push fits are due to either not seating the pipe fully, or a burr damaging the internal rubber O-ring....the former may not reveal itself for some time, though damage to the O-ring will probably be evident right away.

if you are using a new pipeslice then the answer is generally no, i've never had to de-burred a pipe cut with a pipeslice, the only time you may have a prob is if the wheel is damaged or the rollers are stuck & then you normally get tram lines around the pipe instead of a clean cut, as someone else said make sure the pipe is pushed fully into the fitting then you shouldn't have a prob.

Whats he going to do if the shower pipework is in the wall?

Two cuts will be needed, of course, on each pipe and they had better be spot on otherwise putting it all back together again afterwards is going to make for very entertaining watching.
