Hi guys, Quick question for you. We currently have two separate rooms upstairs, one containing a WC, the other is the bathroom. We intend to move the WC INTO the bathroom, but the only place we can situate it is on the opposite wall to the outside wall where the soil pipe needs to connect. My question to you guys is how would I go about running the soil pipe to the outside wall. Ideally, I would like the pipe to double back on itself under the floorboards and pop out of the wall, totally invisible! Is this possible? Can you use smaller diameter pipe until it meets the wall? I would prefer not to use the 'boxed in around the wall' method if at all possible. Any ideas would be much appreciated, thanks.
And the joists run which way ???? from my understanding you will have to run accross joists at some point (which is not recomended with a 4" pipe) With the soil pipe running under the floor with the joists and exiting directly out of the wall you will be ok... but it will mean then connecting to the existing soil stack. Dont use a smaller pipe unless you are using a saniflow !! Boxed in can look ok if done nicely
Cheers guys, thought about this option - Is there no other way besides having a noisy unsightly box fixed to the back of my bog?
Thanks Pengu, the pipe will run in the same direction as the joists, so that is one small blessing. Any idea how much clearance under the floorboards I would need to install a normal soil pipe, taking into account the gradient needed to exit the house (it needs to travel approx 2m). Cheers.
You could box the wall in at say 1200mm with a nice shelf on the top, the cistern can be concealed behind it with an even nicer back to the wall pan
We don't the layout of the bathroom, but you may be able to put the bath on another wall perhaps? Unfortunately, this is the only layout we can use. Due to the position of the window and door, the bath will only fit in the one location, which just so happens to be the toilet's prime spot!
Nice one doitall... a 1200mm box would look a dam sight better than the normal 150mm As its only a 2 meter run, you wont have to worry about the drop (any drop will do) the pipe will be supported as it exits the wall so all you have to do is use a length of metal builders band to support the pipe as you bend upwards through the floor to the pan (a piece of flatened 15mmm copper pipe to act as a strap will serve this purpose if you haven't got any builders band)
I would install some fitted furniture along the W.C wall to hide the pipe or a concealed cistern with tiled boxing and removable worktop. It's not a good idea for the soil pipe to run outside.
If you can get 1" to 1 metre fall in the pipe you're onto a winner. That's what the BCOs like to see for outside falls. CC
Homebrew. You'll be sorry when you're having a nice soak & an infuriated teenager is beating on the door desperate for a dump.
