waste

I've been looking online at a new sink base unit that's listed as having a 40mm void to it's rear? Is it 40mm, or is it actually larger in order to accommodate the compression connections etc? My existing sink waste pipe is slightly over 40mm anyway, with the various connectors being...

It's been many years since I last sorted a bathroom but, sadly, the bullet must be bitten. Obviously, in the interim it's been realised that the faffing about with custom built boxing-in option is laughable, and a versatile off-the-shelf modular option for hiding the pipework away has become...

I’ve seen various videos showing how to fit a new pop up waste – and I'm now realising that this is often done BEFORE the sink and pedestal are finally installed. I can see why. Now, we have no intention of dismantling the washbasin itself after already spending sooooo much time removing the old...

I'm looking to install a macerator in an underground room. I need to pump the waste up to a 4" soil pipe at ceiling level but, because of ceiling joists and the position of the existing soil pipe, I will struggle to do my vertical run first, as I know you are supposed to do. Running the...

The waste pipe on this tumble dryer is especially small diameter. No problem as it comes with an adapter which you put into the compression fitting - see this video; However; what do you do if you have an existing washing machine waste hose and you need to connect two hoses? I don't have room...

Hi I'm not much of a diy expert particularly on drainage. Had this drawing done a few months ago and now I have a waste for sink from plumber and the gutter from roof of extension (see photo descriptions). I had to get a new builder to finish off as original one dug hole and has since not...

Hi - I am installing new kitchen and changing position of sink. Access to soil pipe is 3m from sink and will run behind units with one 90 degree bend. At end of run just before soil path the waste will pick up washing machine and dishwasher waste. Would 40mm pipe be sufficient with...

Hi all, We have a downstairs bathroom with toilet, basin and shower. The toilet is fitted with a Durgo valve. The downstairs bathroom is an extension to the house which was fitted probably 15-20 years ago. We have noticed over the last few months that sometimes a foul smell (its not me...

Hi, under my bath is a waste pipe, with a 15mm pipe going into it, the gap is blocked with lots of silicone, but it seems to be leaking a bit ! I'm not sure where the other end of the 15mm pipe goes The waste pipe goes outside, and is connected to a soil pipe,( there's another waste pipe...

Planning a new bathroom, can anyone see any issues with this waste water design? I plan on using 50mm solvent weld pipe and can achieve the correct fall from each appliance to the soil pipe. I already purchased the basin that came with a waste trap, I am not sure if it is anti-vac or not so...

Hi guys, just after some experienced opinions if you don't mind? We're doing our bathroom at the moment and we've had to move the toilet, so in doing so the waste pipe has had to be moved. I'm just not sure there's enough of an angle for it not to cause blockages in the future. What do you guys...

I have installed a Grohe Talentofill (28991000) now need to connect the waste. As usual the waste now poses a problem. It appears that the swivel waste outlet of the Talentofill had an outside diameter of 47mm. At first I figured this must be a 50mm compatible fitting (as stated in the Grohe...

Hi, Sorry if this is obvious, but I have read the Wiki and the FAQ and can't find an answer. The last trap (there are two after the pipe) at the end of my sink waste pipe has came away from the outlet at the wall. It looks like the trap doesn't quite reach the outlet far enough to fit tight...

Our bathroom basin sink just refused yesterday morning to drain away. After pulling apart all the units I managed to get to the trap, cleaned all the gunk, I then pulled apart all the pipes elbows etc and cleaned huge amounts of goo. All that was left was a short run (1 metre) to the waste...

Hi, I'm slowly renovating an old cottage in the UK and want to switch the lounge into kitchen, and vice versa. I want to place the sink, and a dishwasher next to it, as shown on the image attached. My problem is getting the waste water away over a long distance with inconvenient doors in the...
