Hi all,
Non-plumber here so prepare for some dipstick questions. First of all, I'm having the lead communication pipe replaced by Anglian Water soon, and at the same time having to replace the copper pipe on my side (10 metre run to the house), which I'm doing using 32mm MDPE. My question relates to how straightforward the switch out will be. I'm planning on using an Insuduct box and bringing the new supply pipe in to the downstairs toilet (350mm away from the waste pipes), which is a nicer position that the existing place behind the cooker in the kitchen. The existing pipe goes from the behind the cooker, to the kitchen sink tap, in to the laundry room, and then upstairs and in to the loft where it feeds in to a header tank. This is all 15mm copper from the stop tap.
My first question is: could there be any issue in repositioning where the pipe feeds in to the house? From what I can see, I'm effectively just bringing the pipe in at a different point on the same run of pipe.
Second question: is it normal to have 15mm copper from the stop tap? Currently, in the laundry room, that 15mm copper travels about 5 metres vertically up in to the loft where it feeds in to the header tank, in case this makes any difference to the answer. Just wondering if there's a case where you might use a larger diameter pipe.
Last question: there's very poor flow rate on the two upstairs toilets and one of the basins. I'm imagining that this is because they're feeding from the header tank. Is this likely? Is it normal? (I'll get up in the loft later and check). If this is what's happening, I'm not sure why this would have been done rather than feeding from the main. Could there be a good reason?
I'll be speaking to a plumber about this all at some point as I'm having an unvented system put in in place of my vented system in a months time, but just wanted to get a grasp of how things are working before work gets started.
Thanks very much,
Jimmy.
