90 degree bends in shower waste

[DIYHHelp]

Hi,
We’re currently fitting a slimline shower waste. Due to a tight space we’ve had to put in a few (4) 90 degree bends from the shower trap to the waste exiting outside.

It’s essentially resembling a ‘d’ shape. The top of the ‘d’ being the waste pipe exiting the wall.

Does anyone see any issues with this? Will this many bends cause an issue ?

Can you change them for swept bends

Can you change them for swept bends

They’ve been glued on at the moment so if we change we’d likely have to replace the whole trap

As previous Would likely to be less of a problem with swept bends.

Whats the white bend?

Is there a reason you can’t rotate the waste by 180 degrees? Then a pair of 45’s would get you onto the waste pipe?

As it is now it will cause you grief.

I'm with Ben gee

I was thinking exactly this! What's the reasoning behind a 180 degree spin so the outlet is in line with the pipe rather than bends to go at the way around.
If the tray is going to be sitting on floor you will never access these bends again so keep it straight if you can with an access point where possible.

Change the trap is my advice keep the drainage inline otherwise you risk slow drainage and water backing up, eventually a blockage from soap , shampoo, conditioner and hair debris . Kop

White bend looks like a flexible connector - totally made for DIY market.

I would never use anything with rubber seals in an inaccessible place.
Anything concealed - glued fittings, even traps.

Swept bends are a must, I don't think I have ever seen 90 bends with such a tight radius on a sewer line.

- Disaster waiting to happen -

Remove all and re-plumb

In answer to the O.P question,
Yes it will cause problems, it will block faster than normal and be near impossible to clear easilly.

Is that a rather large notch cut out of an already notched joist?

Redo if poss as you are storing up trouble in the not too distant future.
Glued swept bends are best & as few as possible.
As previously mentioned the setup shown is pants & can guarantee there will be issues.
Can you re-orientate the shower tray, may be a longer run but with far superior flow &/or raise the tray to get good fall to the drain, only needs an inch or two max.
Cheers,
Andy

Cut the black waste back, rotate the shower outlet and connect straight on with a coupler and a short length of waste.

And reinforced with MDF?
