After having tried and failed to find a decent plumber to execute my project, I have decided to take it into my own hands to do the job.
I first started with a simple water heater installation so we can wash dishes downstairs in winter too:
I then removed the last piece of lead pipe in my system and separated my circuits:
Lastly, I started replacing the temporary connections by permanent ones:
Next step is to replace the ready-to-explode steel pipe, but I am failing so far to find the ideal solution to go through my concrete walls!
Still, tiring but rewarding experience, especially as the budget is less than 1k€ including tooling instead of 2.5k€ for the cheapest quote I could get…
