Loft header tank and valve.

[Matthew]

Hi all,

In the loft at the weekend.

Our cold water header tank is extremely noisy when it fills. If someone flushed the loo for instance the noise in the loft is very loud. A quick investigation of the tank showed the valve to almost be a stalactite of deposit, (it must be old). So Im going to replace that. I noticed that there are two types of replacement valves, a part 1 and a part 2.

Which do I need and is there such a thing as a quiet filling valve?

The tank itself doesnt have a proper lid and the previous occupants had just draped insulation across it. So I need to sort that out also.

The bottom of the tank is covered in sediment (or rust) hard to tell. And there is a ring of scale around the rim. Whats the best way to clean this out and remove it?

Thanks, Matthew

I used a high pressure part 2 valve like :

insulation you put around the tank will deaden the filling noise.

Best to change it for a plastic tank, with a bylaw 30 kit (screened vent, screened overflow, lid and tank jacket)

've just done this, but I had to partially reframe the loft around the new location, and also put a sheet of 18mm ply under it. This might be overkill, but I wanted to make sure the tank was supported along its length, with some framing under it to support the mid-section.

BTW, If you're not supremely confident in your ability to get watertight joints i'd leave changing the tank to a pro !

Cheers,

Paul.
