Nope. That’s the wailing sound when you go through your fingers because you had your eyes closed Could be a long night ☕️?

Yup. Cheers.

For a 160mm duct ( penetration ) you mark a 300mm square, with a pilot hole, drilled from indide to out, as the centre point. Cut down the two sides and along the bottom to create a ‘cat flap’ of membrane. Cut the 165mm hole out with a jigsaw, or recip saw if you’re brave, and then foam the duct into the hole. The remaining flap can then be cut into 30mm fingers and shortened, and then air tightness taped to the duct and to the membrane. Use A/T tape to seal the open end of the duct ready for the blower test ( if not yet done ) otherwise just use a bag and some gaffs tape to stave off wind-driven rain.

BCO needs to answer that.

Too noisy. Gets my tinnitus going.

Unfortunately, Obi-Wank-Kenobi, my tiling is of a standard that makes others weep. Mill-ponds wish to be as flat as my work. Strangely, over the years, I have never been tempted to try Tramps-Piss coloured grout. Not sure what it is exactly that's dissuaded me, but may be something in the name...... And now.... time for something to level the playing field........

For completeness, the inline attenuators have a full bore uninterrupted airflow through them. 180mm hole from end to end, ergo zero influence on flow, maximum reduction of nuisance sound.

Length of longest run? On a long run, eg 7 or 8 boards long ( @2.4m per board x8 would allow for a 19m run ) needs at least two people on it. Still easy to lay wet on wet. I understand just fine, and have been laying these types of floors for a 1/4 century. If the job needs more hands to the pump to execute it correctly, then that is what I applied. Never had a single squeak from a single floor, ever. Glad that your method worked, also.

In honesty, I used to be 100% DeWalt, then they went to a place where a combi drill wouldn't last me 18 months.... utter shite. My very first DeWalt combi is still up my attic and still works, after 9 years of taking it all over the world and giving it a proper beating. I have the DeWalt 780 XPS shadowline and that is an awesome bit of kit, but the oil-filled gearbox of my Makita BL impact, which is deliciously quiet for an impact drill, is my favourite. If DeWalt do something similar I could be tempted to jump back as DeWAlt actually do some nice gear again, now. Shame I had to leave that camp due to the then offerings just being complete and total shite.

I fit inline silencers ( attenuators ) between the unit and the manifold boxes. Excellent results, and about £150-£200 for the 1000mm long ones, with the 500mm ones annoyingly close to that price. Last install I put 3x 500mm ones in, and reports are of it being graveyard quiet. 3rd one went on the exhaust duct to atmosphere, to ensure that there was no nuisance noise to the adjoining neighbours property. The flexi duct attenuator option is the cheap seats, but does start to alleviate the issue at least somewhat, however I do not bother with those now as there are better options for not much money. I would not be in the cheap seats for the one device that is running 24/7/365 and which could annoy me whilst I slept. I often get those delivered by mistake, but never fit them. More filters, more points of maintenance, and additional resistance where I would not welcome it. Just fit 1x decent inline attenuator on the supply air prior to the manifold if you wish to save money, but one on each is my entry level offering. Too little money to split hairs over IMO.

Not difficult at all, done it on every floor I've ever laid. You just need to get a wiggle on, and lay each row into each other with the glue still wet. Most rooms are leas than 7m so less than 4 boards long. Many ways to skin a cat though. Poor cats

I may be treating myself to some new toys soon......

You tuck the next board into the previous and THEN screw the leading edge of the previous board, not before. To be done with the glue wet, not left an then 'come back to it'.

Bypass the controllers. Leave the mains inputs powered up to the controllers so you have the displays up. Power the EUFH mats up directly off the fused spur that supplies the mats and sit for an hour or two to observe what happens. If the displays register a rise in temp and the floors start to warm then it’s the controllers, if not, it’s the mats. I’d say it’s the controllers as 4 mats dying together is lightning strike odds.

Almost, but not quite. Makita, is the way.....my young cr’apprentice.

In a nutshell.

Kitchen tap on 10mm will be acceptable, but won’t jetwash the plates. Done that a few times so deffo will work.

Lol. If it was 20 posts back I’d let you off the hook, but all you had to do was look up

Nope, it’s the UVC

Try doing litres per minute flow at the outside tap, Link Then pressure; static ( with all taps shut first ) then dynamic ( with the kitchen sink tap going flat out ). Link Let us know the results. If the results come back poor, then you will need to eliminate the possibility of a compromised mains pipe, so you’d then need to dig down by the street connection ( external stop tap in the ground ) where it enters at your boundary and connect to that temporarily and re-perform the survey.

This needs to be set around the perimeter Link to allow the screws to expand and not push directly against the walls.
