Cold water tank cleaning?

[Nathalie1975]

Sorry if that's the wrong place for this post. If you have a traditional boiler, how often do you get the cold water tank in the loft cleaned/disinfected? Is that a plumber's job? Thank you.

Never heard of this as an issue, found a dead pigeon in one fished it out.

I’ve never done this.

Never, every house I've owned has had this set up and I've never heard of anyone cleaning the tank. Lived in my current house for 30 years and have never done it. Found a dead bat in it once when my children were small.

My husband did ours last year when he fitted a power shower. It was the first time since he moved in over 20 years earlier. Possibly the first time ever.

He said there was a light covering of sediment on the bottom but nothing dreadful.

One extra advantage to having an unvented cylinder (and so no cold water tank).

No tank = no rotting pigeons or bats.

Thanks all, we've been living in the house for 10 years and never cleaned the cold water tank so glad to know it's not something we were meant to do once a year...

I’m sure most people don’t bother.

We don’t have a cold water tank anymore, but if we did then I’d clean it every year or so with Puriclean. It is made for caravan water systems but would work just fine in a domestic system too.

Make sure it has a lid (and insulation to prevent freezing) and it'll never need cleaning.
