    Our water pressure is 3 bar with a flow of 15 litres/min. We have two bathrooms and were advised to go for a 200l accumulator. That advice changed recently and a 300l accumulator was recommended. I don’t know about any formula, and as nothing had changed in the design of the house I suspect the plumber just stuck a wet finger in the air but I could be wrong on that. I can’t tell you how it performs because it’s been sat around for weeks waiting to be installed. It is big. And blue.

    I had considered this but decided to give it a miss due to the relatively low cost of the off the shelf offers.

    So, the over engineered MVHR pre filters are ready to go, along with the over engineered attenuators. I still need to tape and paint the wall before I fit it all properly but it’s gone together well so here’s hoping it all works ??

    You can, but it's not an afternoon exercise, I did my own which took yonks but I was able to try lots of different iterations to get the figures looking good. You could get a PHPP consultant to do it for you but make sure you get one who is properly qualified to take your money - there are some chancers out there. @Jeremy Harris produced his own spreadsheet as he found PHPP to be overly complex iirc, there's probably a copy kicking around on here somewhere which I think several BuildHubbers have used.

    And then there were two. External joints taped with left over airtight tape.

    @Russell griffiths I will (well, somebody will) @Nickfromwales I will. @Bonner I may.

    The over engineered MVHR pre filter arises from the gash bits of MDF offcuts that litter the house. Some finishing off to be done and it’s kept my son off the streets making stuff for his deluded dad.

    @CC45, no I'm pretty stuffed with what I have. I'm quietly confident a homemade solution will fix my little problem though. Time will tell, I'll bare all in due course.
  9. Russdl
    Thanks @Stones et al, that’s sorted then, homemade silencer it is.
  10. Russdl
    Good luck ?

    Something else I can add to the list of ‘never heard of that before’. It’s quite a large list. I was planning on using that eggbox type foam whatever that’s called, what is pyrosorb? It sounds fire retardant at least.

    @CC45 they way I’m set up I only have about 450mm to fit them which doesn’t appear to be enough for any of the shelf ones that I’ve seen.

    We’re planning on a 34mm timber tread, rebated on to a 10mm steel plate. To satisfy building regs we plan on using Perspex like this staircase we saw a while ago.

    How did these work out @Stones ? I'm a bit limited in space for many of the off the shelf version to fit so I may well make my own. Any hints, tips and tricks?
  15. Russdl
    Congratulations Ian, that’s a striking property, well done. ??

    I'd keep it out of the insulation if it was me. Will there be any built in wardrobes or such like that it can be hiden behind?
  17. Russdl
    That's something I had considered doing but I'm pleased to say that I stopped myself, I'll keep an eye out for the Tesla though as that's a little less "stalky". Mind you, if I spot it/him, I won't be flagging him down to interrogate him! It would appear that he actively removed himself from this forum for reasons best known to himself but as @Russell griffiths said "somebody must have peed him off". Did his disappearance coincide with the Buildhub blackout in the middle of this year? It is a massive shame because he was an absolute inspiration.
  18. Russdl
    is that a real word? Oh yes. Thanks, every day is a school day. I’m struggling to see how I’m going to fit it into my daily conversation, but I’ll have a go ???
  19. Russdl
    Only if it turns out ok, otherwise I shall let this thread wither on the vine and pretend it never happened.

    Thanks all. I wasn’t at all concerned about condensation until @PeterW posted the link to the galvanised filter housing, then I thought about it, I’m sure the galvanised option would be a problem without plenty of insulation. My proposed timber filter box ( @Onoff which will now definitely be ply, not MDF) will be painted. Or @joe90 clear acrylic, good thought. I’d be able to see any condensation and crud build up! @SteamyTea I’ve got plenty of airtight tape that would join acrylic, maybe a timber/acrylic combo is the way to go... Oh, and @SteamyTea is that a real word?
  21. Russdl
    Ummmm, thanks for the equations @SteamyTea can’t quiet see how they can help me? (the answer is, your not going to like this... 42) In more practical and less mathematical terms, how can I use those equations to inform my decision on whether to build my wooden box pre-filter or not? Shoving a finger in the air I reckon I’ll be fine.
  22. Russdl
    @PeterW I'm using the Ubbink foam stuff, so that's already insulated, I wonder if my little wooden box pre-filter will cause me condensation issues????
  23. Russdl
    I'm only trying to filter out flies and fluff at this stage, but that could well become a separate issue for us.
  24. Russdl
    @PeterW something else that occurred to me looking at that inline filter box you linked to, that would introduce an obvious cold bridge inside my warm roof. I'd never really considered that with my ply/MDF version, but I guess I could have issues there if I go down the ply/MDF route?
  25. Russdl
    ? Thanks @PeterW I always like to find complicated solutions to simple problems so that is way too straight forward for me, aside from that, it doesn't seem to do the 90° turn that I'll need. And no little shelve underneath for spare filters - or something.
