best to ensure a vertical drop before these dry traps I find, there can be a bit of water builds up before there's enough weight to "open" the membrane

take the humidity limit up a few % and see if it comes out of boost. IIRC ours was a bit oversensitive out of the box and yes, get a trap on the drain

there should be a wee squiggle symbol at the bottom right of the display if it's auto-boosting because of humidity

Umm, isn't that beaded water on the *outside* of the unit, but under the rubber weatherseal?

very like Dewalt except... positive and negative are reversed on the batteries so don't try swapping them around...

is it not a replaceable bladder?

any chance of a photo with a wider view for some context? That looks a bit like a suppression capacitor to me...

Pics 4& 5 is that actually mud, or have you teed him off enough that he's washed out the mixer into it?

Ive just got a gravity flap (with rubber seals) in the pipe up from the hood and it seals fine but can occasionally rattle in strong winds from a certain direction. I really only use the extractor when frying/ stirfrying as generally the MVHR deals with a wee bit of steam fine. I've considered adding either a motorised damper or a Thermobox but have never got any farther than that The MVHR is set up for slight positive pressure as there's a woodstove at the other end of the house. Only if the cooker hood is turned right up to boost does it actually attempt to depressureise the house, on all other speeds the extra air just freewheels the MVHR's supply fan as far as I can tell

purists be damned, I just extract for the short period that the wok is a-smokin.

Is that actuator being energised? Is it actually opening?

how/ why? Considering very few have an earth wire...

you might need a trap if there are LPG cylinders in the locality

are you on a pole transformer? Shared?

do you have cavity trays and weep vents?
