Hello. I need to install a fan to extract fumes from a workroom. I don't need it to run in conjunction with a light etc. I just need it to have it's own on/off switch on the wall. How can I do this? Thanks.
It's not uphill. The pipe goes down at a 45° angle for about a foot then flat for about 4 or 5 feet into the drain. I don't think that's the problem. The trap always has some water in it just below tray level. I don't think that would be there if it was a a problem with the pipe placement.
The waste pipe runs straight out through the wall into a drain.
Would making those holes theoretically help with the flow? It's a pretty short waste pipe so maybe the risk of stink isn't too bad...
I saw on another thread that someone said they drilled a couple of holes into the main section you can see from the top and that solved their problem. Does that make any sense?
There's more to the trap than is shown in the photo I posted. I do think maybe it's just a crappy design though. I might be able to get more access going through the side of the platform but it'll be a right pain.
It's almost impossible to take a meaningful photo but I have attached two. The first is directly underneath the trap. Then the pipe exiting that section to the right. The photos don't show everything under there but I just don't have more access than that.
Yeah I agree with you. Dumb design. The reason I can't access it from below is because of how the cowboy builder built a base for the shower tray. I'd have to dismantle the whole thing to get access.
Hi. I removed a plastic/chrome piece from the top that has no effect on how well it drains. There are two screws I can undo (seen in the first section). This removes the circular piece in the photo and exposes the underneath section. As far as I can tell there are no serviceable parts in there...
