Never knew that! Got any mix ratios? I'll need to consider this for my gate pillars.

Really? I know some users with problems from depression to bat sh!t off their head crazy through it's use.

Presumably, under Boris, nose candy will become a legitimate MP's expense?

I reckon the tapered gussets under the treads go a long way to stopping a 100mm sphere. Not so sure at the ends but that could be tweaked.

Wall drain?

Wasn't there something if they open their estates to the public for a couple of days a year they can avoid iht or something?

Caulk after. The "glue", no nails whatever, dries super quick anyway.

Depending how much of a gap then decorators caulk. Otherwise make up a sanding block the height of the skirting and take the plaster down some. Still might need a bead of caulk.

What ply would you use, WBP? And the pva, normal or the waterproof stuff?

Understood. What if the tube assembly is much longer or are there then other losses?

Why such low efficiency?

Some ventilation 101 please... A 4" bathroom extract fan for instance extracts 15L/s through a 4" duct. There's no restriction per se. First question, does the length of duct impact the efficiency of the extract? The reasoning behind this question then: Taking the screen grab below of a DIY tubular heat exchanger: Assuming the "Hot in" is the extract from the (in this case) bathroom, then to still achieve 15L/s would the extract fan need to be more powerful than normal as the surface area of the extract duct is compromised by the heat exchanger tube up the middle? Hope that makes sense!

Can you not go inside the cast iron then?

This is coming up out of the ground? Won't one of these just push down into the cast "female"? Then have normal 110mm plastic out of the top?

This says good for 100mm on the smaller diameter: https://www.plumbers-mate-sales.co.uk/flexible-rubber-soil-pipe-connector-cast-iron-to-plastic---54000460-889-p.asp

We have no main drainage. The wcs go into the cess pool. The gutters go into a soak away one side of the house, I know roughly where it is. The other side of the house the gutter down pipe disappeared into the concrete path. When I dug the path up the down pipe just stopped in the ground. A few hundred yards down the road is T junction with a fenced off soak away, a big one. Must check our bill.

Glued together beer cans for the straight section then maybe some of this where it needs to pass through the branches. Needs the internal diameter to fit snug over a beer can:

Boxed in now but my 25mm water pipe comes up in blue corrugated duct. I forced a metre of grey insulation down where it goes through the traditional footings. The rolled steel perforated sheet is to stop the tunnel bunnies chewing things under the suspended floor. I then pushed the foam in by an inch or so and filled with Wiska Gel. Expensive and tbh pointless in the grand scheme of things as the rest of the house is hardly airtight. My ducts about 35m long or so to the water meter.

Thinking on these lines: With the hot, moist intake just behind the rainfall head:

Keen to build a DIY, single room heat exchanger based upon beer cans running through plastic pipe. It'll be based on this: https://www.instructables.com/id/Air-heat-exchanger-Made-from-soda-cans-and-pvc-pip/ The article reckons cans inside 70mm dia pvc pipe. I assume 110mm soil pipe would be too large/inefficient?

Painting these cheap embossed Wickes doors... The Wickes instructions say that after trimming and fitting all locks, hinges etc, cut edges should be primed AND under coated before top coating. Keen to use what I have, then the primer can be some MDF primer I have from TS. I think I've a random tin of undercoat, it might even be primer / undercoat. It's the top coat where I'm stuck. Half thinking Dulux Matt Diamond to match the ceiling and be hard wearing/wipeable. Or would a satin be better?

Maybe square meters are bigger than square metres?

I did once attempt to drive an RC car under the suspended floor of the dining room with a wireless camera strapped on. Looking for signs of vermin / their ingress points through the footings. Wasn't a success as too much debris on the dirt "floor". Was considering a Big Trak...

Who was the old and who is this new company? Let's do some digging! My chippy mate, Mr A Mug, was approached by a company ref his existing pv system. They've sold him some storage batteries that are sat on carpet tiles in his loft. Edit: It was a crowd called Energy Target, added 3 panels and a battery, £5K. Anglian Windows cold called on his doorstep and he's bought all new 2G PVCu windows.....to replace his existing 2G PVCu windows. Tw@t didn't even get 3 quotes! Still I scored his old front door that's now my new back door!
