American or Australian pipe fittings

[Dave197616]

Hi,

My partner has a dog grooming hydrobath which has started leaking where the blue flexible pipe connects to the plastic white fitting. The Shower head has a female fiting which is screwed to the plastic fitting with PFTE tape but as its leaking from the other side I cannnot seem to remove the blue pipe as it is glued in. As the bath is either American or Australian and thE supplier wants a small fortune to replace fittings could I replace myself. I have been told that the blue pipe is not British spec so I beleive I may struggle to get the white plastic hose to shower fitting which is marked(see photos) 1/2 SCH 40. If i could obtain wher would I buy from as she needs somesort of connection and support like this not only to join the blue pipe to the shower head but for supporting the pipe etc when she uses shower head.

Thanks in advance

Dave

I would measure it, if it's close to 1/2" as the fitting suggests I would cut the blue pipe and fit a new head to it with a suitable fitting.

Can you disconnect the shower head from that white coupler? I would have thought there would be a rubber washer or similar in there that creates the seal that might need replaced. If you can disconnect it, pop a picture of the inside of the white coupler and end of the head up.

Alternatively, what does the other end of that blue pipe connect to, can that be disconnected and a 1/2" shower hose attached?

1/2" NPS = 21.3mm so a 22mm coupling with Loctite 55 cord might work.

I think you mean the shower has a male thread and the white coupling has a female thread.

This is the white coupling...

According to the tables 1/2 pipe is 0.840 outer diameter...so 21.336 mm.

So a standard imperial solvent to 1/2 female fitting should fit...

The reinforcement ring will help prevent cracking. For metal top plastic threads you may want to use normal silicon sealant....I've found PTFE tapes just work loose after a while.

Hi,

Thanks for all the replies, what solvent would I use to fix the flexible blue pipe to the inside of the female coupling as I have looked at the Loctite but that appears to be for the shower head threaded side

Any plumbers merchant will stock solvent cement...to save buying the cleaner abrade the pipe and fitting with emery etc.

I'm not sure but I think that the blue pipe is the wrong material for glueing to the PVC sch 40 adaptor.
The female thread will be OK as it will be IPS. It will work with correctly applied double wrapped (no more) tape on the male thread.
Where exactly is the leak - photo please.
Going with a compression to Fips might work better.

HI, It is the end of the blue pipe that connects to the white plastic fitting shown on the photo, I have just checked and it appears the blue pipe is glued into the white fitting but leaking through the glue.

The blue pipe could have some Teflon or non-bonding material in it.
Was PVC solvent cement used?
You might eventually have to cut the blue pipe and use a new fitting such as I suggested above.
Problem might then be that whatever is used with a "glue" joint or compression fitting wont hold when its being manipulated constantly - perhaps a rethink & finding a supply pipe that will directly thread on to the male thread - similar to a W/M hose.

what does the other end of that blue pipe connect to, can that be disconnected and a 1/2" shower hose attached?

Or possibly another hose/fitting??
