Missing water tank lid, Maybe tank out of shape?

[usman]

Hi,

I have recently bought a new property with a water tank in the loft. It currently has no lid and is in need of pipe insulation.

I wanted to ask is it possible for a water tank to be 'Out of shape'?
the current dimensions are 112cm(L), 64cm(W at the edges) and 73cm(W in the middle)

The lids which I have found online and in toolstation seem to be 122cm (L), 64cm(W).

Is my tank a funny shape or is it infact 'Out of shape'.

What are the possible options to fix this ?
1. make custom lid
2. fix the tank?
3. any other?

Thanks in advance :)

Some tanks do seem to lose their shape and become almost oval, but this doesn't mean they are about to fail.

It is important to have a lid to prevent debris from falling into the tank and contaminating the water.

If you can't find a proper lid, make one using plastic such as polystyrene covered in polythene. Black bin liners work well.
