Ask Samuele: June 2021

This month, Jonathan from Acton asks…

Dear Samuele,

My friend was horrified to hear that I still have a cold water storage tank in my loft.

Why is this an issue, and should I consider changing it?

Yours sincerely,

 

Jonathan

 

Samuele says:

Ciao, Jonathan! And grazie mille for your question.

It’s still very common for a house to keep a cold water storage tank in the loft.
This is because it is ‘feeding’ the house plumbing using gravity.

But, nowadays, the water supply is strong enough to pressurise the household plumbing without the need for such a tank.

The downside of a loft-based tank is that they can be very old, and sometimes still made from asbestos. Already, it doesn’t sound too pleasant.

Very often, the lid is cracked or missing, and any kind of dust, mice droppings or loose insulation can end up in the water. And this is the water you use to brush your teeth, wash your hair, clean the baby etc… naturally, this isn’t necessarily the case with your system, but it might be worth taking a look at it.

If you’re not happy with what you discover, you should consider replacing it. Or convert the system from gravity-fed (from the tank), to mains pressure (straight from the main water supply), without any storage tank – just like your cold water kitchen tap.

Hope that helps.

Bye for now,

Samuele
