Hi,
the boiler installed in the flat started to loose pressure in March, we notified it to the landlord and, due to he wasn't able to explain us how to refill it, he send a builder to check it.
The builder checked the system and find that the valve under the sink to open the circuit was missing, so he used a wrench to open it, and refill the boiler. He checked his tools and said "i'm sorry i don't have a valve fits this junction, this pipe is too old. Don't worry it shouldn't happen again. If it happens again there should be a leak in the system".
We reported to the landlord underlining that the builder wasn't able to install a valve.
After about 5 months, it happened again and we reported to the landlord, this time we explained him that we are not able to refill the boiler cause this lever is missing. He send us again the same builder which rechecked the boiler, he didn't find any proof of leak, then he tried again to find a valve filling the junction, but he didn't have the right one, so he just refill the boiler using a wrench tool acting on the pipe.
After one week we received a phone call from the landlord that he receive a debrief from the builder and he suggest us to buy the appliance so we can top up the water by ourself and if he need to call out a builder and no work has found we have to pay for it.
I'm expecting the have a proper boiler installation with a proper valve to under the sink in case we need to refill it, is it my consideration wrong?
Should I really buy a wrench and acting to the pipe junction by myself ? What happening if I act in this way breaking the junction and put too pressure into the boiler, maybe break it?
