if all you want to do is pass then i think the value might still be 10ACH? (someone can correct me if i'm wrong) as building regulations suck. i believe that anything below 5 requires MVHR so anything above that then you've wasted your money on MVHR.

 

the lower it is the better it is. your place is a concrete box, right? so should be pretty low. good luck!

Read conflicting things on mvhr . Turn it off obviously but close all vents or remove outlet pipes from mvhr ? . I won’t do anything to guy arrives - just wondering

Save for round the walk on glazing?

I did wonder on that . Water leaks in with heavy rain . It’s not a quick fix as the leak is outside the perimeter of the property . But it’s not a gaping hole either . Assume the impact on this with the air test will be minimal …..

ours wasn't commissioned at the time so we just blocked off the external incoming/outgoing vents. we taped airtight membrane to them. i wouldn't bother with closing off all internal vents tbh. just block the route to the outside and job done.

 

also need to block off soil vent pipe and any bathroom fixtures that haven't got water in the trap.

 

basically any hole that leads to outside.

it's actually quite interesting how much of a difference fixing a really small hole makes when you start getting to very low levels. but i wouldn't worry about the walk-on glazing. the levels you're after unless water is gushing in you'll be fine.

Blocking the route to the outside apart from getting on the roof would mean disconnecting the internal mvhr pipes to the unit .

Put some vaseline over the key slots, you got any?

we just left keys in the locks of the doors and sliders. can't remember if we bothered with the window keyholes

See what he says . I suppose he could suggest just turning mvhr off and run the test and see .

the problem is that every vent has a route to the outside, right? and you can't close off the vents of each individual room as they're fixed in place to ensure the correct flow rates. i guess you could cover them in an airtight material somehow. maybe your tester will know of a way

Erm - who said my vents are set to the correct flow rate . Erm , commissioning / balancing the mvhr - who said that was done 🤣. I’ll just close all the (expletive deleted)ing vents ! 🤣🤣🤣🤣

Was he stuck in the same 60 mile traffic jam from before Bristol and to after Bridgewater.

Took me 7 hours to get through it yesterday.

What a waste of my life.

Don’t know . That 7 hours should have given you time to think about your life . Your purpose . Your worth . The futility of your existence. I reckon a job at the Samaritans would suit me .
