Please see attached photo of toilet waste as is ..... done by previous owner I need to replace the toilet in the custard's home bit worried as I don't think this is either allowed or just not good practise now I will need to change the pan connector anyway but the previous guy has used a normal pan connector straight into another pan connector Flexible ( as photo ) now I want to use if I can soild 110mm pipe connected to the black boss pipe in photo then straight up to into the room above that should be OK but what sort of bracket / support is there on the market to stop the new pipe from pushing down when i insert my new pan connector from above in the room ......or is it just a case of using a wooden prop to stop it pushing down ....only that does not seem to be quite right or a good idea to me ............. look forward to hearing all your suggestions  |

I can see what they’ve done. Maybe they ran out of pipe & fittings! It’s not illegal to do that but it’s not what you usually see.

From my college days I'm pretty sure that you're not allowed to connect a waste into a toilet branch, even those cut outs either side of the tee junction (made especially for a waste) you're not allowed to use those either!
I've some really old "handouts" on this somewhere!!
However, what's been done is done.
You might be able to span the joists with some corrugated iron strips nailed to either side of the joist.
For supporting the pipe.
when you push the new soil fitting home you could try and hold the soilpipe up with a flat screwdriver blade inserted between the floorboards and the soil pipe, then as you push down push the screwdriver up (so it supports it), once it's in that's it (some spray polish or silicon lubricant would make this a lot easier).
I've a similar job to do today...
Good luck.

I only say that as I had to put a washing machine external waste into a different stack in Northolt a few years ago. Thames Water were going house to house & my customer had a letter threatening to fine them if not done! |

Thames Water were going house to house & my customer had a letter threatening to fine them if not done! It's surface water that is kept separate. Water from gutters etc. Toilet water and sink/shower/washer are all together and goes into it's own foul water drain, depending on the age of the house. Older houses had/have combined suface/foul drains so you need to be sure what you are connecting to. |

Ah, I see our Dollop the Plasterer has technical shortcomings when it comes to Plumbing.
Single Stack SVPs(soul vent pipes) all waste pipes should go into the vertical SVP & have a restricted length.

Up until the 60s you were not allowed to mix waste water with toilet water above ground level.
It needed a two pipe waste system of drainage, one soil pipe (for sewage) and separate waste pipe (with a top hopper) for the bath and sink waste. Once in the manhole they were allowed to mix.
To save money a single stack system was designed approved and allowed in the 60s, however, it had some very strict regulations regarding the connection of waste water (non sewage) to it.
Things being what they are the rules eventually get bent and today we end up with horrible jobs like in Astras picture (you even see guttering diverted into the top of the single stack system making it carry waste water sewage water plus surface water these days)!
No wonder the country's in such a mess!!!!

It would appear that the shortcomings here are either with your eyesight or reading ability, I was replying to rocketmans point about having to swap a washing machine drain into a different stack. |

It would appear that the shortcomings here are either with your eyesight or reading ability, I was replying to rocketmans point about having to swap a washing machine drain into a different stack. You’re correct Dollop, I didn’t read your post correctly. Older properties with Two Pipe Systems & combination drain systems were always trapped at the base of the Rainwater/waste pipe stack. This was to collect grease etc. Most of these drainage systems were done in Fireclay & had a trap at the property boundary before entering the Main Sewer. These traps were called Buchan Traps here in Jockoland👍 The Building Regulations changed in the late 60’s & as said, two pipe drainage systems were introduced. This was to minimise the amount of water that was being processed in the Sewage Works. Most domestic drainage systems were plastic after 1970. Some Council Specifications were still Fireclay though. |
