WASTE PIPES FOR BATH & WASH BASIN - Bathroom Refurbishment Pt 4

Today I show you how to install the solvent weld waste pipes for your bath and basin waste under the floor.
We remove the old floorboards, take out the old waste pipes and install the new pipes to the soil stack under the floor. I'll show you how to cut your joists, how to get a good drop on your waste pipes so they drain nicely and how to glue then together using solvent weld fittings. Enjoy!

Holy crap the amount of notches in those floor joists is ridiculous and you've made it worse It's difficult to see the span and where the supports are but I bet it's against the reqs. That floor is going to be like a trampoline.

[@waynewinky2754]

Structural engineer here. Just check your bearing width between support walls, whether external or intermediate walls against the load/span tables, and use some common sense. The joists in the video appear to be min 150 x 50mm, could even be 175mm deep @ 400-450mm centres. Notching 40mm out of them reduces a 175mm to effectively a 125 x 50. Span for existing members looks about 2m with an assumed dead load for a bathroom of 0.25 - 0.5 so you could if installing new get away with 120mm deep x 47mm C24 @ 2.37 - 2.39 clear span between supports. It's not ideal what he's done and some reinforcement for additional stability should be provided to spread the weight. Only heavy item as a point load is a filled bath. Humans on flooring as live loads could comfortably walk on 120mm x 38mm wide joists at around 2.3m span without permanent deflection.

Just a quick one mate, how come you use solvent weld for waste pipes I’ve always been a push fit type of guy myself but wondered if there is an advantage in solvent then push fit.

[@thatcornishcockney]

Solvent less likely to leak, push fit can pull apart over time and if its under a shower tray for example itll be a nightmare to fix. there is a place for push fit but id always use solvent personally

[@Superfandangoo]

You just don’t notch a joist this deep, the regs are there in black and white for the purpose of protecting the structural integrity of a building and the safety of the occupants. Waste pipes that need to go through a joist should be holed in the centres of the joist not exceeding 25% or 0.25 of the depth of joist and put between 0.125 and 0.400 of the span for belt and braces glue and screw ply over where the hole is to be drilled. A notch no deeper than 0.125 of the overall depth with same consideration of same limits between bearings. This video should have a warning to people that have come here for advice as this is wrong in many ways, possibly dangerous and costly

[@Superfandangoo]

[@denkitney8865]

Pps, great vid"s as always...

[@danielgreenaway6468]

It’s extremely unlikely for it to leak if you use enough solvent cement and if it does you just have to cut the pipe work leading to the leaking fitting and then coupling onto the pipe work and put a new fitting in.

[@antoniogalluccio4213]

So when the college stress you that you can only notch 1/8 of your joist depth and drill 1/4 of your joist depth, it is all bullshits. Same like chasing a brickwall 1/3 of the depth vertically and 1/6 horizontally, is that right cause I see plumber chasing 43 mm pipe horizontally in brickwalls

[@jklplum8ing816]

I have a bath which is slow draining. I have run a drain coil/snake all the way from under the bath to outside. I have remove the U bend and other two connector pipes that I can access (before it goes under the floor) and cleaned them all out. I have also checked the air vent on the bath (connects the plug hole area to roughly where the taps are) As far as I can see and tell there is no obstruction, but when taking a shower, you end up paddling in a few inches of water. The bath does drain completely just extremely slow. Could it be something as simple the correct angle, they ofc don't angle up but maybe not enough down. Any recommendations what I can check?

[@Luke-hg3qc]

Can anyone tell me if its ok for the sink waste pipe 32mm to go into the toilet waste soil pipe before the stack as that's what my plumber has done and he told me that's fine but I thought they have to be separate ?

[@rjamsbury1]

He said he was going to add an air vent in too which addresses the concern. Without that, flow from one appliance waste can suck on the trap of another, causing gurgling or even pulling the water out of the trap.

[@kingofthetrowel1725]

I’ve just asked same question mate 😂 I have a 32mm (around 1m length) washbasin waste that bosses into a wc branch (around 2.5m length) that goes into stack ,stack has an aav on top boxed in as its internal , I want to know if this is upto regs as I’m getting a building inspector soon. I thought the same that all branches need to be separate not combined. If a smaller aav is fitted on the 32mm waste pipe or a anti syphon trap would this comply with building regs

[@TheHeavyend81]

Why have the double away and back in bends at the stack end. Surely it would have been neater to have put the ofset bend under the floorboards at the basin end which I'm sure would have aided a much better flow, running the pipe 2'' to the left thru the joist as you look at the basin. Ending up with three bends in the run as opposed to four.

[@petemo2266]

Why did you not want to use the old pipe run for the basin save making more runs in the josts? Seen lots of videos talking about not cutting into host to much.

Don't. If you do and something happens like a pipe bursts brings the ceiling down and your unlucky to have a insurance assessor take a gander and sees the notching you could find yourself with a house that's uninsureable until remedial work is carried out. From personal experience I can tell you insurance companies will find the smallest transgression not to pay out and put you on a black list.

It’s definitely not this way. If you’ve a waste pipe to go through a nine inch joist you need an angle drill with a hole saw and drill through the centre of the joist obviously the waste pipe will be inserted with a few straight connectors. Never notch the top of a joist this deep. 0.125 of depth for notching top of joist or 0.250 for cutting hole in centres and from bearing to bearing span 0.125 to .40 not the middle nor up against the bearing 👍
