Soil pipe advice

[mutley racers]

Below is an image of a soil pipe I need to run. What is the best way to run the bends at the bottom of the stack so it doesn't cause induced syphon age? I think 2 90's would be a bit tight so was thinking maybe a 45 and a 90?

Also what do people think about using a flexible waste pipe to go through joists? The joists are 250 and my run is 500mm from shower to soil pipe? Or is it best to just drop down below and box in?

Rodding eyes? Even if my pipes are in the ceiling voids or boxed in will I need to put rodding eyes on all 90's for the building inspector to be alright with the install?

Cheers chaps

Theres no Image

But always use swept bends or 45 instead of a tight 90
and i'd avoid any flexi waste pipe where possible

ground floor wc should go straight to dran and a soil shouldnt have bends in but in the real world just put rodding access at every bend and where posible use 45s

 

[plumben]

as above either use 45's or use a long radius swept bend for each 90 with roding eyes, only need enough that you can rod both ways instead of going mad with roding eyes

The architect has decided where the runs of waste go. It's nuts

Crazy pipe runs. Especially ground floor and 1st floor toilets. I need to try and put an access at the bottom of the stack to put my bung in to test but not sure the best point as I need to test the ground floor toilet as well?

Oh, so are you saying to put rodding eyes I voids for basin waste and toilet?

Dog leg with two 45 bends at ground floor ceiling/ first floor, floor level. Then long radius bend at ground floor level with access hatch above. Avoid flexible waste, they become brittle and split.

if thats new build you will need to put the ground floor wc on a seperate drain how is the ensuite connecting to the soilstack or is it on a saniflow?

For you bung, usually stick it in the manhole, thats what ive seen anyways

It's not a new build. A total refurb. I told the site manager about the toilet going straight to drain and he said he will sort it with building inspector.

There is a soil pipe on the outside wall of the en suite.

Today they have asked me to quote to do underfloor heating on the whole ground floor!! Just keeps getting bigger and bigger

I don't mean to pee on your fireworks Mutters, and I really hope it all works out well for you. BUT!

1) Negotiate stage payments and enforce them
2) Never have more money invested in the job than you can afford to lose
3) Don't assume that because the first payment turns up on time that you can drop your guard
4) Don't take anything at face value. There are people who specialise in ripping off less experienced subbies, and they are highly skilled at it. In the early days, they are all sweet reasonableness, but its as phoney as a Nigerian email. Credit check them. Find out what happened to the last plumber. Talk to the other trades on site.

+1 for this, I know you've said your good mates with the site manager but i wouldn't let that give you a false seance of security as the customer might take him for a ride too

Does anyone else think that Rays in the wrong job

I have worked for the project manager for 4 yrs now working in some big churches and he has always paid as soon as invoiced. He got the building company in but said he wanted to use me for the plumbing. When ever I want paying I just invoice and it's paid next day.

I do totally understand where you're coming from and I shall invoice every Friday so I can pay off credit card.

Cool.

You still need to watch the paper work between you & the builder as he will try to blame you if things start going wrong.

Remember the old adage "there are NO friends in business"
