it keeps things interesting. if it all worked how it was supposed to life would be boring.

qq....which hep2o decoupling kit? SF has 2 on offer and I'm not sure what the difference is 1. https://www.screwfix.com/p/hep2o-push-fit-hepkey-plus-set/5222j 2. https://www.screwfix.com/p/hep2o-push-fit-demounting-tool-set-4-pcs/1208j and do I need these? https://www.screwfix.com/p/hep2o-hx77-15w-push-fit-heptool-set/9951f

getting better under the expert tutelage of the buildhub experts.

that should be starting tomorrow. don't worry I'll give you all a good laugh with my sub-par attempts at running pipework.

gave me time to do my nails

are you referring to the strap band solution? if so, it definitely wasn't going anywhere! but, as I'm sure you're all aware by now, my plumbing skills are rudimentary (but I'm willing to learn guv!) and so when experienced pros tell me to do otherwise I do as I'm told.

I thought it made a nice pretty pattern

thank you. every day is a learning day. 🙂

I learnt from the best......I mean @pocster

Please sir. May I have my job back. 🙏

that'll make a change.

union rules state I need a written warning first.

you both mean here? and how am I supposed to bend a threaded steel rod?! I don’t have a rebar bender.

my electrician said Prysmian was the best so I got that. best price I found was Screwfix. the Prysmian LSOH from SF ended up being very comparable to standard PVC from others!

@Nickfromwales @Russell griffiths @saveasteading, is this better?

so I'm presuming that if I do as @pocster suggests: for each outlet once the pipe is run and connected up I can get a real world idea of actual flow rate and as long as that's before I board everything I can always run a larger bore pipe? the beauty of a manifold system I guess.

Can you change the PRedV to allow a higher pressure?

I'm not worried about the shower and the dead-leg removal tbh. my shower controls will be outside of the shower tray so I can start the shower without getting wet and can wait the few seconds for it to get to temperature. the HRCs will be on the basins as I hate waiting for hot water when wanting to wash my hands!

I'm not planning a hot return for the shower but the hot and cold will be the same distance (give or take a short amount for the difference between the hot and cold manifolds). I can only presume that in a pressurised unvented setup the water pressure for the hot and cold are the same? so I'm also presuming that with a blended temperature at the shower end it's not an accumulation of hot + cold water pressures, right? therefore measuring the cold feed water pressure/flow rate will give an indication as to the flow rate at the shower head?

yeah. new 32mm main direct from the pipe in the road. our existing supply off the water main in the road is shared with 2 other properties so I'm expecting a better pressure/flow. I'm just curious is all! just one of those things that my brain needs to know.

one of the jobs to do on my list is to check my static pressure and flow rate just so I can double check everything.

right. looked at the sump and it's the same as I was looking to use in our sump for the water from around our basement. so it's a simple 2 pump sump that pumps water to a ditch or something like that. as it's dual pump it should have redundancy in there so I'd say it's highly unlikely that both pumps have failed. if you lift the lid how high is the water level in there? is it just a faulty sensor on the alarm? could you use a hose to put a high level of water in there to simulate a high water alarm to make sure it's all working?

oh...just followed your link. seems your tank is just basically a sump so doesn't have an overflow.

sorry can't help but our RWH tank has an overflow which isn't pumped. so if the tank fills up gravity takes over and overflows the excess out of the tank. ours was from rainwaterharvesting.co.uk
