Shower fixing and testing


Pocster

Recommended Posts

I’m really having a bad day - can’t concentrate. Lost a family member over the weekend - so that can be today’s excuse ?

 

I’m being thick for sure .

The mixer outlet ( top left ) need to fix to the shower elbow bottom left . But because ( as far as I can tell ) the shower elbow is ‘more forward’ ; they aren’t nicely inline .
So from shower mixer fittings would be

 

1/2” BSP

90 Deg spigot 

90 elbow 

90 elbow 

 

then down into the back plate fixing .

 

Just seems way too many fittings for such a short run .

 

Second question is when I water test this I really need to ‘block’ the shower outlets yes ? ( head and flexi hose ) . So that I have water pressure right to the final destination and can leave over night to test .

Does it have to be plastic?

 

I would bend a piece of copper to do that.

 

Not sure if I would get 2 bends in that space so it might be a 45 degree bend to kick the pipe out from the wall then a 90 degree soldered elbow to take it down.

Plastic for everything .

No idea how I get the spigot out as the key won’t fit ?

But how do I pressure test at the final point ? . The end fixing for shower head etc. have these funny things ! . Really want to cap them for proper test .

What goes on there then, some sort of quick connect thing?

 

All that springs to mind is the story about the boy sticking his finger in the dyke...

Unscrew your shower fitting from the wall elbow and screw a 3/4 male blank in.

Yes but then I’m not testing the entire fitting . I could do that , it doesn’t leak . Then put their fitting in and it could leak ...

Yes - some special thing with a grub screw ( which I’ll lose soon )

Okay, so put the shower hose fitting in your picture on, fit the shower hose with a 1/2" male blank in the other end of the shower hose.

Ok - assuming that all fits ( which I guess it should ) what about the shower head ? (2nd photo )

Same problem, tidier solution.

 

Same idea could be achieved using a inline kink in a piece of copper pipe. Would require a pipe bender though.

 

I also fitted a bunch of valves so that I could test the system / make a mess from air & water shooting out unexpectedly.

Yes should be easy to cap that to test it.

 

P.S it is handy having been doing plumbing for years and having a big box of assorted plumbing fittings (I never throw any away) so I can usually rummage in the box and cobble up something for most situations.

Put water through on the cold feed only . Lots of knocking - assume air in pipe ?

Have a leak on one of the brass fittings - so will fix that first .

Does the mixer need hot and cold simultaneously ? I.e prevent the knocking ? . I have no hot available but could stick cold on the hot feed ...
