Welcome Jonny. Looks like an exciting project. I found Cornwall planning dept to be very reasonable and pragmatic. Good luck with your application. There is a wealth of encouragement and information here in the Buildhub forum - now is a good time to have a read back over previous posts/threads before things start to get too busy for you!

I would echo the above with respect to Openreach - we had ongoing problems for about 6 months with BT trying to establish a connection. The Openreach fools engineers turning up, assessing the job as needing to go on the 'too difficult' pile, and making excuses not to do it. I made a complaint to the Chief Exec of BT, and this got me a complaints handler who persevered like nobody's business to see this through. In the end, the connection was made. The heroes engineers that did it accidentally gave away that this one had been in their office for some time, and no one wanted to do it as it was hard. At the end of all of that palaver, we received over £700 compensation (the statutory amount per day), which paid our broadband bill for more than two years. In the interim, we were using an EE 4G dongle which worked really well, despite the 4G signal here being a bit iffy.

@Nickfromwales @marshian Advice taken, many thanks.

Thank you!

@Nickfromwales I have now removed the pipe and am planning to turn the corner and bring it along the hallway wall instead of the laundry side. You mentioned using two 45° bends, rather than a 90° - is this to turn the corner more gently and reduce the risk of blockages? Any other advice? Thanks!

Thanks. I will have a look at how far along the hallway wall I can bring it before it comes through. I could maybe disguise it by building out the lower part of that wall as a little shelf feature. Watch this space!!

Thanks @Nickfromwales I should have explained more…. the upstand is only a temporary thing that allowed us to use appliances before making the laundry room up into a proper utility space. The plan is to have a four-unit sized (roughly 2450mm) run along the laundry room wall with dishwasher (later to be replaced with tumble drier), washing machine, sink unit, and fridge. I shoved the upstand in last year just to allow us to have use of the dishwasher and washing machine. My plan now is to take that out, and fit a proper sink P trap with double nozzles for the two appliances in the final location, as HWMBO is fed up of swapping over the two drainage tubes every time we use the appliances. (I’m also doing the incoming water connections to allow both appliances to be connected at the same time instead of swapping them over, which is what we have been doing.) The upstand location is 1550mm from the R hand wall, which is essentially where the middle of the laundry sink will sit. The fail in my plan was to buy a McAlpine sink trap, which I now find won’t connect with the existing Flo-Plast pipework, and that is what I was looking to BH’s hive mind for. Having said all of that, I appreciate your plumbing wisdom, and wonder if you still think the waste pipe is too high if it is only connecting to a sink P trap and not having the upstand in place? Thanks!!

This is the other side of the wall, under the half-landing. The plumber set the first 400mm of pipe coming out from the soil stack, and I took it across from there, and then through the wall. Where the waste pipe joins the washing machine upstand the top of the pipe is around 500mm off the floor. (This was my first ever go at plumbing, so please don’t judge too harshly!! 😳)

Thanks, yes when I first did the waste run I realised that the plumber (who had put in the soil stack and a nominal piece of waste pipe) had used solvent weld pipe, so the push fit fittings I had bought had to go back to SF to be changed for solvent weld. When I bought the washing machine waste upstand pipe fitting, which is a compression fitting, I was surprised to find that it would fit onto the solvent weld pipe. The sink waste with the double appliance nozzles is McAlpine. This won’t connect to the existing solvent weld flo-plast pipe.

Today I decided to start to learn plumbing - cue a very frustrating day with some comical moments. I’m at the point of changing the temporary appliance waste upstand for a sink P trap with double appliance nozzles where the laundry room sink will go, and have hit some difficulties: Stoopidly I didn’t realise that each brand of plumbing parts are slightly different in size, so the McAlpxxx trap won’t connect to the Flo-plxxx pipework. I’m also uncertain about how to arrange the connection of the P trap to the incoming waste pipe. Photo attached of existing waste arrangement. (The end of the horizontal pipe sits where the sink waste needs to go.) The Flo-plxxx double nozzle P trap also gets appalling reviews and isn’t sold at SF. Is there an alternative brand that will connect to the Flo-plxxx 40mm waste pipe? Any suggestions how to configure the sink waste to meet the horizontal pipe? thanks!

Thanks - no I didn’t get an answer to this, so had filed it under “things to deal with later”. Very helpful to know.

Very well done to you both. You remain my inspiration, and valued source of “been there, made that mistake, here’s what I learned” advice. Looking forward to having a G&T on the glorious gin balcony!

I’ve heard that Totem timber in Plymouth is good for straight wood…

No, we didn’t have any problems with water, this was just part of the original plan for the house, to protect the foundation slab. Shillet tends to have water sit on it a bit, then it will drain away given time.

Thanks for your replies. This is the description given in the quote: This doesn’t describe the pipe having a sock or being wrapped. However, my understanding was that it is simply part of how a French drain is installed. We did discuss the pipe being wrapped in membrane when he came to quote for the job. The ground is shillet, which is a sandy/stony type of soil.
