I've tighten it a bit and seems to have stopped the drip. Thanks for the help.
Another question, what should I do/not do about the blue/green dried up stuff on the top and sides of cylinder (pics attached)?
Hi, new here with no plumbing idea and need help.
I've noticed a slow drip on the pipe above the boiler (cylinder) and a blue/green puddle on the boiler (cylinder) from where it's dripping. Also some weird foam like thing on the pipe.
Please see pictures attached.
Does anyone know what this...
