  1. I'm installing a 16kw air source heat pump next week, and need to put in a spot to anchor it. I'm wondering if people can comment on how they've installed them and what has worked? I'm aware this ASHP will put off a lot of water (60-100l a day) and there's an inlet for sewer/waste water (it's a combined one system) about 4ft away from the installation point I've chosen. Should I put down some combination of sand, gravel and top off with cement? Or just small cement bits for the footings for the ASHP mount points? And what about water drainage? I can run some 40mm pipe from top of the pad, or a kind of soakaway. I'm just not quite sure whether 100l is too much to just drain in place. The ASHP is downslope slightly from the sewer inlet which is only about 2" below ground, so it's likely I'd need to run pipes above ground from ASHP. Would love to hear what you've done, and what has worked - and photos if you have 'em!
  2. Hi all, I have recently moved into a new property and am struggling to figure out what to do with my drainage system and have recieved a lot of conflicting information from various people. This photo attached shows the current situation: For context, I live in a basement flat with 1 other flat living above me. The large black pipe at the front of the picture is their soil pipe. My washing machine and kitchen sink go into the gully(?) and relevant pipe however I have my own drain system at the front of the house for all other stuff. As you can see the pipe connects to next door, which is a story in itself in that apparently whilst building an extention, the contractors jumped over the fence and connected the drains on our now property to theirs (when they were previously not). This was unauthorised and without building control approval etc. They then didn't fix it. The council at the time, after this happened, said the piping could no longer be buried as next door would have insufficient fall and the drainage would be poor. I have contacted a few people to try and fix this as obviously it looks not visually appealing, and as far as I am aware may be against building regs too. Some have told me to try and bury the pipe again involving expensive damp proofing etc, others have told me to concrete over the top, others have told me to deck over it, and others have told me to rearrange piping so not as obtrusive. I'd really appreciate any advice, particularly around the best ways to arrange the piping or if anyone knows anything regarding the regs about waste pipes being unprotected above ground etc. Cheers
  3. Can people please tell me if the end of the pipe that goes into the 110mm pipe be solvent welded or is it just push fit? TIA
  4. Evening all, Just getting around to fitting our free standing bath and just battling with the waste. The next job is to connect it up to the waste pipe under the floor - but I'm not sure of the coupling. The waste pipe that came with the bath looks like this The end that needs to go into the waste has an external diameter of 39mm - in fact it seems to be tapered slightly from just below 39mm up to just over 39mm - does this get glued into a solvent welded pipe? or do I need to find a connector? Does anyone know? Cheers
  5. Hi All. I was speaking to the building control officer this morning and discussed altering the soil stack and relocating the waste stack on the back of the house so I do not need to have penetrations through my new extension roof. He agreed that I could take my main roof gutter water over the new roof (as long as I show the area and check the gutter pipe sizing tables etc.) he also agreed I could cut my soil stack low, take a 92.5° bend from above the T jct. where the WC is connected, run it along horizontally within the extension roof void and pop it out the wall rather than via the roof - that is easy and will mean just boxing out the pipe within the extension which is not a big deal. I MAY move it round the corner too but for now, that is the plan. So the next pipe to deal with is the 3 inch cast iron waste stack, as I can run gutter water over the new roof I can therefore take the waste stack down lock stock and barrel, this services the main gutter, bath and sink. Looking at the bathroom wastes and with some PB removed in the kitchen below it looks like I could run a piece of waste pipe between 2 floor joists, pickup the bath and sink and core through the wall and come out on the wall round the corner from where the waste currently exits - within about 750mm of this is the waste pipe from the kitchen, so some digging will soon reveal a pipe I can build a manhole onto and connect the new waste pipe. See sketch attached, yellow is existing, blue is proposed, NTS and just rough... I don't really want to add a 110mm stack down the side of the house, to catch a sink and a bath I think it is just excessive anyway, so I would like to use 82mm pipe, it doesn't appear that common and there are not many parts available for it but it looks like I can get all the bits I need. Plan would be, new 82mm waste pipe on the outside wall, then a T branch (if I need air admittance) or 92.5° deg bend through the wall, mortar that in, then push a stub of 82mm into that and then downsize the rest of the run with a 40mm to 82mm pushfit boss, I would also run the 40mm pipe further into the 82mm than needed so that it effectively just poured down the external pipe and reduces any likelihood of leaks from the boss in the future. How does this sound? This is simple and non invasive enough that I could do this little project almost immediately so I am not faffing about with pipes when trying to put up my timber kit. What are you guys doing for your external bath and sink wastes when not using 110mm? Most google hits show these huge ugly 110mm stacks... The other option being considered is move the soil stack round the corner (much more digging) and then tying in the toilet and the bath and sink into the one pipe, but that is another story.
  6. Im just planning how and where my soil pipes are going to poke up through my slab and I'm wondering what others have done for their 50mm waste connections. Always keen to save space and as I know where everything will go could I just have 50mm wastes poking up for every appliance and sink? If I use a strap boss from the soil pipe underground is this a bit stupid if it ever fails? Seems like it might have less chance of failure down there than surviving being beaten around by rebar and concrete. Either way can I get 50mm elbow into ducting? or is there no point even ducting the horizontals as the only wiggle room required will be horizontal..
