Replacing cold water tank - worth it?

No chance will it add even 1p to the price of the house.

You are likely to have problems with getting a new big tank to the loft.

There is no point in replacing plastic with plastic only because of the age and some dirt at the bottom. It's much easier to empty it and clean. If you can't find a proper lid for it just use a sheet of plastic film/membrane. Or polycarbonate.

grumbler -  the old plastic tank looks like part fibreglass plastic!  The new tank would be the same size, slightly taller.

What's wrong with fibreglass plastic?

My tank isn't that old, but it's MUCH bigger than my hatch and the only way to install it was when building the house.

I think it is definitely worth it, not least because the new tank is compliant with the byelaws and the old tank wasn't.

What are the new cold water tank/system byelaws? If I were selling the house, would they check the water system in the loft?

Thank you for your comments

A surveyor might check the water tank, maybe not.

I doubt it would be a big issue

Some water tanks in the loft feed water for toilet flushing and bathroom taps - thats why drinking water should only be via the kitchen tap. Although the tank is also fed from the mains, the water may sit in the tank for a while and can have debris at the bottom. So based on this it worthwhile changing your water tank.

No way would I be replacing the water tank due to a bit of debris on the bottom. 

Clean the tank by all means but replacing it for debris (that could occur in the new tank) why ?

The OP can only tell the condition of the tank and the amount and type of debris. Certain softer plastics start to degrade

His tank doesn't have a proper lid. That alone makes it worth replacing in my opinion.

These types of tanks, without a lid, have been known to end up with dead birds in them, etc.

You're brushing your teeth and showering in this water. I prefer to know it's really clean

When I bought this house, the tank had a broken down old lid.  There were a few bits of random rubbish in the bottom of the tank, but the water was crystal clear.  I didn't want to try cleaning the tank as that would just stir up anything in there.

I made a new lid for the tank, and left it at that.  Haven't been poisoned yet.

Thank you for your thoughts, very helpful   So recap - problem - tank has debris but... the tank is hard plastic, lid covers it well, water is crystal clear, never been poisoned .  It's that darn debris  -   the tank could be flushed out and cleaned as suggested. But how?

Just close the tap, and wait until the tank gets empty. Then remove the debris manually and wash the tank if you wish. Get rid of the dirty water, then refill the tank.
