Old & New Bath Taps & Connectors

[jaydebruyne]

I went to a job the other day to change a bath mixer tap.

It's fed with 22mm copper with what I'm sure were 22mm x 3/4" female iron couplers. Attached to the irons were 3/4" to 1" offset connectors which the tap screws onto.

The existing pipe distance is 180mm. The new tap is 150mm.

The tap I was going to replace it with has a similar threaded offset connector but is 1/2" x 3/4", the tap connecting to the 3/4" side of it.

I can't seem to find a 22mm x 1/2" iron coupler, so can I get different threaded offset tap connectors????? I'd need a 3/4" x 3/4". I'm a little confused... Would I need to reduce the 22mm copper to 15mm in order to fit a 15mm x 1/2" iron?

The pictures might make it clearer :/

In the wall you've got 22mm (or 3/4"cu) x 3/4 F.i. ?

You want to put 1/2" M.i (the new tap offsets) into the wall ?

= 3/4" x 1/2" brass reducer in the Wall.

Why not just use a 1/2" brass bush & use your exiting tap & offset connectors, rather than looking for 1/2" to 3/4 offset connectors?

I think a bush is the best option.. I didn't think of this at the time. Was a majorly bad day! Cheers guys, much appreciated

I'd use loctite sealing cord also as it allows you to twist or undo the trappings without fear of the bushes leaking in the wall... Or so they say anyway lol!

I'm going to have to take some of the tiles out and hack off some plaster to get the the iron aren't I?

Hopefully not, depends if the old ones unscrew from the wall...

id make the bush onto your offset Tap tails first & then screw them into the wall

Thanks for the advice gassafe [emoji106]

Use Loctite 577 as it locks the fitting in place as well as seals it.

 

[jaydebruyne]

If the last guy did that then I'm gonna have to replace the irons, no? Which means taking tiles off etc

No they will still twist out if they are well fixed in the wall but the y could be attached to a bit of plastic

 

[jaydebruyne]

The pipe isn't securely fixed in the wall, I can move the fitting around the hole in the plaster/tile with my hand

Get some heat on the old fitting if needs be, but don't crack the tiles lol!

Post up a pic 2moz of the finished taps 😉
