yes just floorboards. ive ripped up the 18mm plywood, not sure if its marine ply :/

can i get a 12mm marine ply and put a 6mm backerboard on top? do i need to use some sort of https://www.tilersforums.com/forums/tile-adhesive/ with the backboard if i do need it?

cheers

I personally would remove all floorboards and lay minimum 18mm WBP ply and then overboard that. Dont mess about with thin ply, it doesnt comply with British Standards and it will fail

do the floorboards not run underneath the walls and would it be more difficult to remove them? if i dont choose to remove the floorboards what would you recommend using on top of them?

cheers

Qwerty

You will have to check if they do, but even if they are I will nearly always remove them. You can overboard onto the floorboards but you will probably find there are holes everywhere for pipes etc and boards are poorly fixed or warped. I perform full refits so I take up the flooring 90% of the time to amend plumbing

here are some photos of floor and piping for radiator. how far down should i cut the pipe in order to put a bend on it? is my diagram ok for what i plan to do? my terminology is crap so please tell me exactly what parts i need. you will see from photo diagram of how my radiator is and the other diagram of my proposed look when ive sorted the pipework.

can i use plastic pipe on copper or just copper? is there a preference. i realise this is a tile forum so im assuming some you you professionals tackle this type of thing everyday....maybe im wrong :/

should i replace the floorboards with a thicker plywood? my intentions were to keep the floorboard as it is 22mm thick and seems in a reasonable condition. my issue is what thickness should i replace the floor with and how thick a backer board should i use on top? is this the recommended way forward? can i use a thicker than 22mm plywood??

thanks in advance

I would suggest you visit our sister forum- www.ukplumbersforums.co.uk

From your photos though I would seriously check out the structural integrity of the joists. I can see alot or rot and cut away areas of joists

here is where my drain valve is in my dinning room :(

also, since i cant join the plumbers forum just now can someone advise on the best way forward for the u bend from bath? can i have the wast from bath go straight down and underneath floor boards with the u bend going straight into the pipe? or do i need to have the ubend above the floor line meaning i have a s shape trap as shown in photo with the waste going straight down adding into the pipework below floorboards. is there any pros/cons of having it above or below?

cheers

If there's too much fall before the trap it can end up being syphoned out , also it's obviously better if you have access to the trap for cleaning.

please define how much the fall is? what is the tolerance before a syphoning effect happens? i reckon the distance from the bath to the connecting pipes below floorboards would be about 1 to 1 half ft max.

cheers
