Need to avoid two 90° bends?

[wst100]

Hi, all

Newbie here.

My family is renovating our bathroom. As part of the design, the toilet has been moved to the left by about 8 inches.

Unfortunately, due to the presence of main drainage pipes outside - we live in a tall building - the contractor has to use an 8-inch horizontal waste pipe with two 90° bends to connect the toilet. Even though it has a slight slope, I am concerned that clogging or other problems may take place in future. Can any fellow forum members possibly suggest a remedial solution to minimize the risk?

Thanks in advance for any ideas.

Will be fine. No reason for it to clog

Agree.

Doubt it's 8" - over 200mm as that's usually for underground works, maybe 4" - 110mm?

Should be fine as long as you're not stuffing wads of nonsense down the toilet.

I read it as 8" long...

If he does mean 8inch long then it looks like 50mm waste pipe?

Thanks, all, for your helpful input.

I was informed that the waste pipe's diameter is 4" (100mm). Perhaps it is longer than 8". I didn't actually measure the thing.

It seems like everyone here thinks the two 90-degree bends won't affect the flow in any material way. Most reassuring!

Thanks again.
