Toilet Tank Bank Flush Cistern Insert Water Saving Device

I bought a few of these Toilet Tank Bank water-saving inserts and honestly, they’re a no-brainer. Dead easy to install – just fill with water, seal it up, and drop it into the cistern. Took all of two minutes.You can immediately hear and see the difference with each flush – less water used without affecting performance. It’s a simple, effective way to cut down on water use, especially if you’ve got older toilets that aren’t dual-flush.They don’t get in the way of the mechanism, they don’t float about, and they don’t cause any issues. Just quietly doing their job, saving money and water with every flush.Perfect if you're looking for a cheap and effective way to reduce your water bill or just want to be a bit more eco-conscious without any effort. Recommended.

So Far So Good, I have done tests (Probably used a weeks water messing around) and found it saves exactly 1 litre of water per flush. My cistern seems OK for it, as its an older one, the bag hangs on the side but almost touches the ballcock but doesn't affect the operation. All that remains is to see whether it stands the test of time, not puncturing or whatever as others have said in their reviews. As I don't know about this yet I will give it 4 stars, but if it last a year it would have got five !

Recommend this it saves water and money

Difficult to judge. It did not fit my slimline cistern by clipping to the side so I took the advice printed on the item and laid it in the bottom. This restricted the flow as the ball was prevented from dropping right down when flushing. In trying to push the bag down further, it punctured, took in air and tried to float, further impeding the ball valve, so I had no alternative but to bin it. If you have a large cistern (and consequently use a lot of water when flushing), then I'm sure that the device would be fine.

Good product saves water

This item a bit on the 'flimsy' side [ the plastic being a bit on the thin side] so it needs careful handling. Easy to install but would not be suitable for a slimline cistern. Does the job however.

I was a bit nervous about whether this would work as planned but it's been straightforward, easy to fit and completely forgotten about in the 2 months since I installed it. No difference to the flushing experience, it's just there doing it's thing quietly. Highly recommended.Other reviewers have highlighted it's no good for dual flush or narrow cisterns so do check if either of these apply to your loo.

Unfortunately, properly filled this got in the way of the ballcock in my cistern.
