I went up to the loft to put a few items away & noticed the roof felts had lots of condensation especially near the top area. After doing a bit of research online about the subject, condensation in the loft as well as watching some YouTube videos, the advice & cheapest solution is to install some felt lap vents Purchased 20 felt lap vents, installed them as close to the eaves as possible, also near the highest point, ridge/apex area, every other rafter bay as recommended (5 on the top, 5 on the bottom). Repeated this on the opposite side. I went up to the loft to check a couple of weeks later & the condensation had almost completely gone, I still remember it was very windy weather, yellow warning, strong wind on & off during that period. The weather had been very cold, freezing in the last few days, I went up to the loft to check again only to be disappointed to find the roof felts condensation has returned but not as bad as before. Although the weather has been very cold, there wasn’t much wind, quite still air so I presume the felt lap vents requires a good amount of air flow to work so the stronger the wind the longer the duration the better. I’m thinking of purchasing another 20 felt lap vents, installed them between the spaces of the eaves & highest point, middle area every other rafter bay, repeat opposite side. Any Idea by doing this would improve the condensation problem? What is the idea amount of felt lap vents installed to be the most effective? Is having too many felt lap vents installed would make it less effective? Is condensation in the loft a very common problem during cold spell, should it eventually clears up on its own with windy/warmer weather?

Any idea if the shower is still safe/ok to use for the time being until I find an electrician to check it out? It trips the RCBO intermittently when you using the shower for aprox 15 to 30 minutes, you have weeks when nothing happens, everything seems ok? No tripping the RCBO with a quick shower!

Changing the 30A to a 40A RCBO is the advice from other members based on the shower 8.5KW, 6mm cable size & 30A RCBO?

The 30A RCBO only started tripping intermittently recently, no problem beforehand? Would changing the RCBO to 40A solve the issue?

Never had any problems with the cartridge fuse, don’t remember it ever blowing so maybe just swap the RCBO back to the original cartridge fuse?

It’s the wife, not the children! 🤫

Don’t think it’s recommended to replace it with a 40A RCBO as the cable size is 6mm? 40A RCBO requires 10mm cable?

The shower unit is 8.5kw, cable size 6mm, 30amp RCBO The shower unit was originally wired to 30amp cartridge fuse, never tripped, very reliable, replaced to RCBO years ago. Thermal overload, is this the thermal cut out switch, what is the fix for this?

Electric shower keeps tripping the RCBO intermittently. Seems to be doing this when you’re in the shower for longer time, over 10 minutes plus? It’s ok with shorter time spent in the shower, having a quick shower? Is this a fault with the shower itself or the RCBO? Any idea or advice ? Do I call a plumber or electrician to have a look at it?

The asbestos test kit I ordered on Amazon UK cost £34.95, includes UKAS lab testing fee, you send a sample back to them, they do the testing in the UKAS lab & send you certification of the results back by email. It’s just your standard UKAS lab asbestos test kit widely available!

I’ve just ordered an asbestos test kit on Amazon UK, get it tested is the only definite way to find out! Yes, the bottom line, we all learn from our mistakes too, more wiser next time! Thanks for all the advice & replies guys, all helped sharing your knowledge & experience on this matter, very much appreciated 👍

Logic tells me to wet wipe clean the vacuum cleaner, replace filter, wet method of cleaning the carpet by shampoo or hot steam cleaning should be sufficient. Scaremongering, contradictory information & fear is to take no chances whatsoever? All this starts playing tricks on your mind, not good for your mental health either!

What I’ve done is probably a typical asbestos DIY mistake, drilling/cutting holes many out there would of encountered so what is done is done! To be honest, I’m more worried for my family members living in the same household than for myself I’m now trying to move on & here’s my plan of action to manage the situation as best as possible as follows: I have a steam cleaner, using a hot wet cleaning method on the carpet so would this be any good? Leave the vacuum cleaner running outdoor for 5 minutes or so, replace filter with brand new one so is it ok to use again? Replace the carpet & get rid of the vacuum cleaner, is this just being OTT or over cautious? Hire a H class vacuum cleaner with Hepa filter as this is the recommendation for cleaning carpet with asbestos, quite expensive to hire one out & there’s also either a decontamination charge or you need to have it clean by a specialist with a certificate to prove it’s free from asbestos before returning! Only a handful of asbestos cement dust was initially vacuumed up so would I actually need to hire a H class vacuum? It would be a lot easier, maybe even cheaper just to replace the carpet than hiring a H class vacuum. Any suggestions?

The plasterboard material I cut into is dense, hard, can’t really see flakes or fibre on the cut edges I’m certain it’s asbestos cement board Handful of dust on the carpet, vacuumed it up, wet wipe it down, is the vacuum cleaner & carpet contaminated ? Dispose both the carpet & vacuum cleaner to be on the safe side?
