And you have to guess them as they bear no relationship to their manifestos.

Most shower wastes built in like that are "top access" and they have some form of "bucket" that lifts out from the top, it is this lift out but that forms the trap and you can lift it out to clean it. If all you see looking down the rectangular hole is the pipe heading off, it might have a part missing and hence not forming a trap so the smells get in.

Almost any pump of that size will work, the Wilo are good because they are very quiet.

I thought that shock outcome HAD come true and people are now tightening their belts nervoulsy awaiting the budget to find out how much poorer they are going to be? Local house builder here has SHUT one of his sites because the houses on the first site are not selling quick enough.

Hi and welcome. you are in good company, and most of your questions will be answered by reading this blog of another member who has done what i think you are wanting to do.

That was a case of bad electrician rather than poor planning. when I was wiring new builds, I would take a walk round the shell of the building with a marker pen and discuss with the owner where they wanted sockets, switches etc and price on what they wanted, not what some random architect who was never going to live in the property had marked on the plan. Sole trader tradesmen live or die on their reputation and recommendation. If he ripped you off, don't be afraid of telling anyone that asks and don't recommend him. All my work came from recommendations.

A bit more context is needed. Why are they looking at the retaining wall? Is it failing? Are they expecting to come onto your land to repair it? Are they blaming you for it's failure?

For the inner bathroom a light tunnel or solar tube works well, we had one in a previous house to light an otherwise dark landing and it worked well. That revised layout flows a lot better.

Hi and welcome. Lots to work out in due course. But I will start with if you build with enough insulation and air tightness, you won't need heating upstairs.

Re submit planning for one house and the mobile home shown on the plans as temporary accommodation for the build and to be retained. If it is all one plot as far as planning is concerned then keeping a caravan in your garden is permitted development. The fact it has planning at the moment as 2 dwellings is what is scuppering the plan as the other plot is not part of your garden so you can't have a caravan there as permitted development.

The only way I solved whether mine was getting enough flow rate or not was to fit an in line flow meter. If you are not hearing any noise, it could be the pump is seized, but the Wilo pumps are one of the quietest pumps available.

No trickle vents so how do you KNOW you it is "well ventilated"?

I make it clear I charge by the hour. So would you rather pay me at an electricians rate per hour to move furniture, or would you rather move it yourself and pay me less? Simple question.

If that is ALL the insulation you are fitting on a (assumed) un insulated floor, then the electric UFH will be very ineffective and very expensive to heat as a huge proportion of the electricity used will just be heating the under floor space. Most people consider a minimum of 100mm thick PIR type insulation to be required. And in any event electric UFH is probably the most expensive way to heat a room, and no means to repair a fault in the heating mat if one occurs.

At probably £200 per pump out, it would soon be cheaper to do it properly.

Hi and welcome, you are in good company.

Looks like the cheap gold plating has failed. Wrap the replacement in self amalgamating tape, and honestly a bit of vaseline smeared on the connector pins before engaging keeps water out. (I do this on boat connections)

Just watched it, (rarely watch commercial television live) Under budget, under time and no major problems. Kevin was having to dig deep to find any tiny little problem to highlight no matter how small. A model of just how to do a self build, and a great result. Of course it only went so well because of all the expert advice and encouragement from Buildhub.

This seems popular according to google https://www.diy.com/departments/nature-calls-composting-toilet/5060542053747_BQ.prd

Why not build or buy a composing toilet so it is only grey waste water you have to deal with?

This is the sort of thing most touring caravans use to collect their grey waste water and wheel it to the appropriate drain on a site.

This is the Marsh portable treatment plant designed to slide under a static caravan. It will discharge grey waste water that still needs to go to a soakaway or possibly to a watercourse. https://www.theseptictankstore.co.uk/shop/marsh-portapura-m5-sewage-treatment-plant-5-person/#:~:text=Description,also perfect for glamping accommodation.

That is an "aquaroll" other makes are available) for transporting fresh drinking water to a touring caravan. Nothing to to with waste.

Marsh make a small "portable" treatment plant designed to slide under a caravan.

He is making it into a "high integrity" CU with as you describe one way not protected by either RCD which is okay for the SWA. He needs to have the appropriate extra cables inside the CU. Some will argue if it is not supplied like that by the manufacturer then it is no good.
