Loft water tank lid

Peter1988

Hello, we've just moved in to our new home and on our homebuyers report and upon closer inspection I've seen that the water tank lid in the loft had collapsed into the water tank sinking with it some insulation so the water is murky and dirty.

I took the cover downstairs into the garden and opened it to see it was corrugated plastic with insulation inside within a waterproof plastic (thick bin bag type material) covering it.

the corrugated plastic had been cut to ensure the various pipes could go in and out of the tank, but I cant seem to find a lid which is the correct size on all of the obvious online diy shops etc.

Can anyone advise what I should do please?

Thanks

Peter

Make one out of a piece of ply. Then clean the tank right out. On second thoughts do that first.

Thanks for the reply. What sort of thickness plywood should I get? Also, should I insulate and cover the ply as was done initially with the corrugated plastic?
Thanks

Doesn't really matter and I wouldn't bother insulating unless your roofspace has high arctic conditions. Its pipes exposed to nice cold drafts that freeze. Never really seen the point of those silly plastic bag thingys tbh. The main point of the cover is to keep dirt, dead birds, rats, burglars etc out of the tank.

Really appreciate that, thanks!

Hi

Do not use a wood product of any type.

It will attract moisture, rot, support mould and insects.

Look on the side of the tank (the PC term is cistern) and see if there is a manufacturers label.(sometimes embossed into the plastic)

Some are now unavailable.

Use copper tube to support the existing lid and cover as best you can in the event you can't get a replacement.

Any more than any other type of timber in the roof or the wooden platform that the [STRIKE]tank[/STRIKE] cistern sits on?

I kinda wish I'd put that fiver down now.

Who'd want to burgle a cold water tank?

I was in the same situation and made one from ply, slightly bigger than the diameter of the tank top. The finished article was too big to get through the rafters so I made it in two pieces. I lined the underside with plastic, folded on to the top edged and stapled into the ply. The two sections can hinge on the plastic to get it in place and then are held in place one in position. Seems to work well.

You never know.;) I see I missed out "the occasional disoriented wildebeest" from my list too.
