I tried disabling the DHCP server in the Router menu hoping that DHCP requests would make their way to the original router, but sadly not. It isn't obvious how to have it act as a switch. There is a Bridge option, but it says it only supports one device at a time and has to use mobile data. With it acting as a Router (inc DHCP server) I can happily RD to a machine on the other network as well as shared drives

For the two turns, I think I'll use Osma 4D960 plus two bends as I've identified a cheap source and didn't like the look of their 90 bend chamber (4D918) and the total cost of that was looking like £100+ each. The first corner can be achieved with a total turn of 2x22.5=45 if I bring the pipe out from the house at 45 degrees. Despite all being level invert, it says to always use the main channel rather than make the turn with the chamber's 45 inlet. I loved the look of the Polypipe SFA7 option but it's too expensive.

Made a few calls. Polypipe suggested that Bottle Gullies are the standard approach. Wavin (Osma) said it was down to taste and Bottle Gullies are probably the easiest and neatest. I said I liked the idea of hopper and rested bend and that seemed ok but may be less roddable. In terms of joining the main run of pipe, it's standard to use a tee, as long as the main run is roddable (ie chamber at is ends). It's looking like I'll go with an Osma 4D960 with 2x45 bends at each corner of the house, straight runs between those and then Y-tee branches to each hopper or gully.

Brett Martin's B2803 is a 90 degree 280mm inspection chamber, but the exits have a sharp 45 bend with the channel being straight within the inspection region. Osma's 4D918, on the other hand, has the bend in the inspection region. Osma have a useful selector, a copy attached. Slightly bigger though, 315mm vs 280mm. Here's some information about their Multi-Base IC range. The Osma 4D918 looks a bit silly from above, but there is a straight alternative (4D910) that could be used with 45 elbows. Even the smaller (250mm) Osma 4D960 could be used with two 45 elbows. Brett Martin B2803: Osma 4D918: Osma 4D960: F0026752_0001.pdf

That makes for an about 15,000mm * 1/60 = 250mm drop from the stack's rested bend to the tee by the 450mm chamber which has an invert of 600mm. That means the rested bend can have an outlet invert (600mm - 250mm) = 350mm below the surface. That works about perfectly to have the Floplast rest bend at the bottom of the stack (D571, dimensions below). If it was available in black, I'd consider having the collar sticking out of the ground meaning the invert could be at just 300mm below the surface. The orange stuff isn't UV stable and would catch the eye, but I guess I could spray paint it black if I needed to.

Good advice, I'll take a look this evening when the wife isn't watching the awful movie she currently is. It will save her subjecting me to it's sequel.

Looking at table 3.1 in Part K it looks clear that the minimum height for internal elements in a single family dwelling is 900mm. A block of flats however would require 1100mm as would an external balcony of a family dwelling. I just got spooked by a call with Richard Burbidge where they said I need 1100mm even for a singe dwelling. I checked with my BCO to make sure and he says 900mm. -----

Looks smart, but I'm using a shoe rather than pipe straight in so I'll use something with a grate on the top surface

I'll have to check my levels, but may struggle to get a rested bend in and have a good gradient as well (1:40). The longest run is going to be about 28m so 1:40 would need 700mm which may be optimistic even from the surface let alone a rested bend. Most of the run will be under paving so can be near the surface.

Where do they get in, through the ring seals?

No, it's running its own DHCP etc so the network is fragmented, but OK for now. Means I won't be able to access any shared drives or remote desktop from that end, but that's OK for now.

Gullies or traps are essential if the rainwater joins the sewage system. That's not the case for me as it's a separate system going to a drainage ditch. I have shoes for the bottom of my downpipes. Bottle gullies on first look seem like a good idea, but I have seen people elsewhere saying they aren't the right thing to use but with no clear justification. I know they can be expensive, but that's not the reason. I think it may be that the bottle gully would need to be right up against the brickwork, rather than having a hopper arrangement like Marley's UG47 which they proposed to use with a Marley UG44 trap (shown at bottom of this post). These traps aren't roddable and bottle gullies are in theory, but would they be in practice? If you have a branch (tributary) coming away from the house at right angle, I suspect the rod wouldn't be able to curve down into the trap's outflow and so it ends up unroddable. A different matter if you use an inline bottle gully, but that requires the pipe run to be close to the wall and I am keen to have a bit of separation (also need to go round a chimney outcrop). Perhaps putting the branch at 45 degrees would help with rodding access, but the ultimate access would be provided by an inspection chamber of access where it joins the main pipe. That seems over the top though. Is rodding access a red herring for rainwater as the blockages are local to the trap and not in the pipe sections? What do others think if the right approach? Marley UG47 and UG44: Looks like you have to solvent weld a length of pipe to UG44 since there's no rubber seal and anyway the outflow is higher. Toolstation's Aquaflow has a ring seal but that feels like tempting fate as it's still below outflow:

Pre-existing WiFi Router <~~~> WiFi Range Extender with Ethernet port <--> 100m Ethernet Cable <--> WAN Ethernet port on a WiFi Router <~~~> WiFi devices (e.g. Laptop)

I couldn't find anything that combined a long range wireless bridge and WiFi access point / client into a single product that only takes a power connection. I didn't want the hassle of Ethernet to a wireless bridge at each end, so I've actually kind of done the opposite since I already had the bits: WiFi Range Extender with Ethernet port <--> 100m Ethernet Cable <--> WAN Ethernet port on a WiFi Router. The WiFi Range Extender with Ethernet port is a TL-WA850RE V6 by TP-Link and the WiFi Router is a 4G+ Router (B535-333) that I am no longer using for 4G. In theory, that could provide 4G backup as well, but I don't have a SIM in at the moment. Cost is minimal at £75 (£14 for TL-WA850RE, ~£50 for 100m of Kenable direct bury cable, £20 on eBay for the4G+ Router). Hopefully it won't get struck by lightening as I have just draped the cable along the ground. I think I could have a WiFi Range Extender with Ethernet port at each end, but I didn't have two. Manuals for TL-WA850RE if needed. 1910012385_TL-WA850RE_UG_REV6.0.1.pdf 1910013049_Range Extender Setup Help_REV1.0.0.pdf 7106508795_TL-WA850RE(EU)_QIG_REV7.0.1.pdf

Good thought, but that won't apply as both houses have sewage treatment plants
