Plumbing Adaptor

Is it imperative the valve looks downwards??

You could just change the valve for an angled washing machine valve, making it easier to catch the water when disconnecting the hose.



This would be a straight swap for the old valve, you could probably still use the nut and olive that is on the old valve making it a much easier fix for you

Hi,

Spoilt the game a bit by posting photo but still....

You are required to fit a double check valve if you intend to use the hose outside for watering /car washing.

I would suggest the following.

Fit a 15mm compression tee and run the existing w/m tap off the top.

Next a short piece of pipe with a female iron x copper compression fitting.

After that a hose union bib tap with a built in check valve. A Hoselock adapter on the tap and you have a permanent arrangement.

Is there a prize?

Thanks for all the replies guys! Think I'm nearly there.

I hadn't thought of taking the valve off before (partly as it is tight access so it may be tricky). Once I remove it, is it worth trying pushfit (eg wickes polyplumb) instead of compression? Or are they likely to fail?

Speedfit/Polyplumb are just about idiot-proof. Don't forget the inserts though (he says, never having used the inserts!).

You will need to cut the copper pipe back beyond the olive.

Speedfit is unlikely to fail - we had some freeze in the garage this winter and rather than pushing the pipe out, the fittings themselves burst!

thanks, wont i need a special tool to cut though (not supposed to use hacksaw looking at it)

Rats - CH beat me to it!

If using plastic use Speedfit or Hep2O. Polyplumb is carp. However don't see the point in this instance - you still have to convert back to a femail iron which won't be in plastic. Follow CH's advice.

For cutting pipe you can use a hacksaw - just make sure you cut it square, don't squash the pipe and deburr the cut. Otherwise use a pipecutter or pipeslice.

Cheers

thanks. 2 very different views of polyplumb! Looking at the poly plumb info, it's fine to use with copper pipe so dont see the issue with the fitting being plastic. My concern is the difficulty in removing the existing fitting and putting in any sort of compression fitting. I'm not sure I can even get a wrench in there!

i have one of these for pipe cutting. worth its weight in gold.

Hi,

I take it the photo you posted is NOT the real situation you have?

If it were then access to dismantle the fittings would be easy.

All I can say is ,it was installed so therefore it can be uninstalled.

I would avoid the push fit.

All the joints are 'o' ring and do not grip the pipe in the same way as brass on copper compression joints. They will flop around at all angles.

A junior hacksaw will do you just fine and will cost a lot less than a pipeslice, as you are on a tight budget.

Hi All,

I am looking for something which I'm not sure exists.

Eg similar to the Y piece adaptor here
http://www.4cleanerfloors.net/cgi-bin/product.pl?PID=213690&query=FLDPLUMBING%20FLDTAPSADAPTORS&path=66991,325402:325429,513505

But it does not need to split in two & it should be n shape. Eg, fits to the thread facing up and leaves a thread facing down.

Thanks

Have a look at this link Hope it helps :beer:
