I get all that I just can’t comprehend it.Agreed you should
A be charging for it
B know how to sort it if its goes tits up.
We take em off as we are city and guilds qualifed plumbers but we can still run the risk of knackering the boiler then I'm really buggered
I wouldn’t even do it if I knew how and charged for it. £20 or something for that risk? No thanks. And you’re even more f**k*d if something goes wrong and you’ve charged. No way out then.
Sometimes customer takes them off. If they’re on I skim around but can do it so you can’t tell.
