Shower waste

[Russdl]

I'm boarding the ceiling of our living room which is the underside of the main bathroom. First fix plumbing has been completed in the bathroom but when I look at the shower waste (pic 1)

 

Firstly it's not connected to the drain pipe. (pic 2)

Secondly it's not connected to the shower tray. (pic 3)

Thirdly the 'natural' position of the waste is not parallel to the base of the tray, it diverges around 10-15°. (pic 4)

 

So the questions are:

How do I fit the shower waste to the drain pipe and ensure it NEVER leaks?

I'm told I can board the ceiling and leave the waste disconnected from the shower tray so it can be fitted from above at a later date. Is that a good plan?

When it comes to fixing the waste to the shower tray there will be a fair bit of force on the waste pipe because it is not naturally aligned with the shower tray. Will that present problems later down the line?

Personally I would want to fix everything and test with water before boarding over.

Would you consider that ‘first fix’ or is that a mix of first and second fix? I would certainly be happier if it were all proved to be water tight before we boarded.

not sure about that but I water tested all my plumbing before boarding simply fir peace of mind, I really did not fancy having to rip out anything to find a possible leak ?

Likewise, sadly we already have one shower tray (over the kitchen) where the waste hasn’t been connected. I wrongly assumed it had before boarding the kitchen ceiling. I knew this waste above the lounge wasn’t connected to the shower tray but I was slightly stunned to to discover it wasn’t connected to the waste pipe either.

have you plastered it yet?if not perhaps best not, much easier to chop a bit of plasterboard out before plastering , you can tell a slight weep with a dry finger on the joint if you test it with water, but this may take months to show through a plastered ceiling ?

@joe90 Yep. The kitchen is all finished so naturally I’m fretting a bit over that and I have now stopped work on the living room.
 

Which is inconvenient.

Are you paying a plumber to “ second fix”? If so just point out they will be responsible for any damage if it leaks ( might make them try harder?)

@joe90 First and Second fix...

in that case if it were me I would ask him to second fix, where possible, and test before anymore boarding. Blanks can always be in place fir testing purposes. Some may say I am being fussy but peace of mind is worth a lot ( IMO).

 

edit to add

 

First-fix plumbing is essentially the pipework for space heating, water supply and waste water drainage. ... Second- fix plumbing is the connection of the appliances, their testing and commissioning. Appliances include bathroom sanitaryware and radiators, as well as boilers and other equipment.

 

IMO although the above says second fix is connection of appliances, where it is essentially in a void to get covered over I would argue it’s first fix. Ask your plumber to “ humour you” and connect and test hidden pipework.

@joe90 thanks for that clarification on what constitutes First and Second fix, I think it is that grey area between the two that has been my problem. I’ve assumed stuff was done that in fact was not done. Every day is still a school day.

Funnily enough I had problems with my electrics, the builders electrician was very good (and a bit OCD like me) but during second fix one of the rings was “disconnected” (diss) between two sockets and we had to turn them into separate spurs. Just shows that testing stuff before covering it up is invaluable ?
