Most of this isn't my work including the non-vertical hw feed to the pump - at least its 22mil copper. Slightly ahamed to say I did do that odd looking tee that pulls water down and up to another shower - it was what Mira asked for but can't believe folk do that in the real world ? Where would the misus put the sheets ?
Anyway, side tracking again - tomorrow the new Grundofs pump is arriving and no doubt I'll have to make some alterations to get it to fit plus gonna fit check valve and AAV as per PB's rec.... If it starts sucking in air Tom can have a good laugh and say "told you so". If that happens I'll move to plan B later in the month when I'll totally change the HW outlet of the pump so it doesn't loop (you can just see that loop at the bottom of the pic).

Always worth trying although I find anything other than a direct replacement always has a sting in its tail.
So you'll have four AAV installed.

That shower together with cylinder was the last time I used a tradesman. The same polish plumber put all those AAV in. The one just before the pump is needed (it turns out) as used to get terrible problems filling the system back up. |

They dont make the qt80 anymore as far as I know  Mind you I've been living with the sting in the existing installation's tail for years. I've never go to the bottom of why it performs badly and is full of air. It didn't help he originally plumbed the flange draw offs the wrong way round so I had to change that. |

Well as usual Battle was spot on. There was a fking sting in the fking tail.  Got the pump in there on a multi-layer foam and stone sandwhich. Plumbed it all up. Tested hot side for leaks no problems. Opened the cold lever valve and that horrible sound - hisssssss The polish plumber (yes I've got it in for him even though this isn't really his fault) - his end feed joint was leaking. I must have heated the joint up as I was soldering close by. If only I'd wrapped it in a damp cloth the next comedy of errors might not have happened ! I tried to re-sweat that joint as shown in one of Tom's videos. Well Tom makes it look easy. By doing that I'd fked up other joints close by. I think by then I was using a cloth but maybe not damp enough. So I tried to repair 2 joints and when I switched on after the second one about 2 joints were pissing water. I'd had enough so will carry on tomorrow. The stupid thing is that section is only the cold feed to the pump and is at the front of the cupboard so really easier than the 3 other connections. I've decided I'm gonna rip that leg out and throw those fittings in the bin and start afresh tomorrow. |

There's certainly a large conoglomeration of pipes and fittings in the cupboard dd.
I'd fit a compression joint then work back towards it re piping in copper - it couldn't have been that good joint in the first place to have leaked, you do come across them from time to time.
Up and at em' - it's a new day.
Tappy,

Well, for the record its done now. I chopped out the section and redid - pretty quickly. I think you have to be a natural or have soldered over 1,000 joints to start getting fancy with re-doing them etc. A natural I most definitely am not but I keep trying.... Yes its a rats nest of pipes in there. The plumber that installed the HW cylinder originally could have done a bit better I think. Still I've never installed a HW cylinder but I imagine its bloody difficult and dare I say it a lot harder than installing a boiler  |

I'd like to say well done DD it's done by your fair hands! |

I would agree to the dafty, on site work, when i was a site plumber a cylinder was priced at £25 to fit, A boiler was priced at £35, so everyone jumped on the boilers and left the cylinders because there is so much work in a cylinder, plus you're in a tight space and they are mostly upstairs and you're on your knees for 3-4 hours,  |
