The fall on the inspection chamber would be the wrong way. They are designed to flow 3 into one not 1 into 3! It may be the requirement for a rodding point and a place to see if the water is dissipating and the drain is not clogged up. I have accesses each end of my surface water soakaway for these reasons. I would have offered two Y junctions with the straight on rising to a rodding point. Good luck M

We built/renovated a smaller property than we could afford so we only considered cost engineering on each task on a value for money angle. It was enough doing the work without financial pressures. I also have a feeling that any pie chart would be very personal to the actual building and only be indicative to any building. M

Hi @kbsoloman I don't expect that the blockwork was put up without reason. More pictures will help. Or draw a rough sketch showing more info: how long is the wall to the left of the picture. Whats behind the wall How high is the ground the other side of the wall Otherwise tricky to comment. M

How much are the gaps 5mm? 30mm? Not sure if you are saying if you can get temporary access to both sides when filling? In my humble opinion non-compressible material should be used under every vertical stud position as a minimum. I always used a dry sand and cement mix 3:1 just damp enough to hold together when squeezed in my hand to pack gaps like that. Packed in tightly in gaps and allowed to set. Good luck M.

This sort of thing requires individual home personalised management to be successful. I need a full car battery for tomorrow's journey and have filled it using our PV. If it is used when no PV is available during today I would have to buy electricity during tomorrow to get home at twice the price of what it would cost me from home.

41% of my last electricity bill was for the standing charge and VAT.

😂 and what did you expect! Long hair I guess.. On a more serious note what was the average wattage over square meterage when you were away? ( I assume this is used energy not purchased) We run on about 3kWh purchased per day at the moment but have PV and EV, however this is all the energy purchased for everything - no gas.

Hi @Sam45 Yes there are many choices of this type of wall called retaining walls. Its worth searching "retaining wall design" and go to images. You will see there are many designs. You may also see solid brick walls that get wider the deeper they go... Designs that allow for drainage either through weep holes or drainage to foundations or back filled with drainage material depending on the soil type, slope and existing drainage ground water levels and so on are also indicated. As you say the wall needs to be attached to the base, however, again, there are many choices but basically, depending on the design the bigger the heel or toe of the foundations the less chance of failure. Whilst the mix of views may seem confusing, the answer, as always is in the maths and someone competent to calculate it and come up with the design that will achieve it. @Mr Punter, @Conor, @ProDave, @Redbeard and @Iceverge have all come up with good information. I wonder when the neighbours paving was completed and if the sloping land was levelled at the time bringing the earth higher on the failed wall. Any builder would know that the wall without backing would fail.... Best of Luck Marvin

Hi @Sam45 In my humble opinion, I would not go for a two wall design. If you did, the only thing holding the wall up would be the strength of the strongest designed wall. The other wall would only be for show. The ones I have build retaining the high ground to about 3 feet high have the wall becoming thicker on the ground side the further below the level of the high ground it goes. As @ProDave comments, the best design is for the thickening of the wall to be under your neighbours ground.

The problem with the waste, in my humble opinion, is that the solvent weld vertical pipe is too short. What with the short length of pipe catching the fitting and the vibrations from the flexible grey waste pipe its going to fail. Another thing I do is dry off the sink first downpipe, and all the bits in the compression end of the junction pipe that grasp the top pipe, and silicone the parts, fit together and hold in position for 48 hours by propping. However, I still would not do this without lengthening the vertical solvent weld pipe. Good luck Marvin

Yup cooler air drawn from the north side, through the bungalow.

Hi @GNB88 There are a few who have done what you are doing, definitely in Scotland. As some? rules are different in Scotland from England make sure you point this out when posting. M

Hi @KevH Welcome. What sort of garden are you thinking of having? M.

We find when its really hot the sun is out so we use a mobile air conditioner which has a heat pump. It doesn't do the whole building but then we tend not to be in most of the rooms.
