## Overview

The Toilet Tank Bank is a simple, maintenance-free water-saving device that fits inside your toilet cistern. By reducing the amount of water refilling after each flush by up to 1 litre, it lowers water consumption without compromising performance. Made from antimicrobial, non-corrosive materials and equipped with a clip for secure placement, it’s ideal for older toilets and helps you cut costs while supporting sustainable living.

## Description

The toilet tank bank is designed to be filled with water and inserted into your toilet cistern. This means that when the toilet is flushed the cistern never empties fully and thus you save water as less water travels back into the cistern after flushing. Ideal for older cisterns in particular which can have a flush level of between 9 and 12 litres the toilet tank bank is made from non-corrosive materials that resist microbes and fungal growth. One toilet tank bank can take up to 2 litres of water and it has a air lock fill valve so that no water ever evaporates and thus you never have to refill the bank making it a maintenance free product. The product also includes a clip for attaching to the side wall of the cistern so that it fits neatly in place and won't float around the cistern and get caught in the toilet mechanisms.

Review: Instant Water Savings -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.
Review: Great Product, saves 1 litre per flush. But how many flushes will it take ? - 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 !

## Questions & Answers

**Q: Would dropping a water bottle into the tank do the same job?**
A: It would reduce the amount of water required to fill the cistern but the Tank Bank is flexible and can allow for the ball valve to drop without fouling. I could not use it because my cistern is already quite small and there was not room for the bag.

**Q: Has any found this help with condensation? Inlet water is sooooo cold to our toilet**
A: It's not meant to help with condensation! It's to cut down on the amount of water returning to the cistern after flushing, saving water.

**Q: Surely placing a clean Brick into the cistern, would do the job?**
A: It would seem so but it depends on the shape and size of the tank. If it is a slim-line model, then you might need the bag to fit around the equipment.

**Q: How often do these need changed?**
A: I'm not sure,  but will keep an eye on it to make sure it keeps it's inflation. I imagine it will last for ages unless it perishes!

### ⭐⭐⭐⭐⭐ Functional
*by M***A on 25 August 2025*

Fits our top button flush cistern. Certainly reduces the amount of water being flushed, any less water and no.2's wouldn't flush cleanly away. Clips to side easily and the lid isn't lopsided. Some have complained that the bag punctures. The plastic seems robust enough and shouldn't puncture easily, although how it would puncture in a protected environment like a toilet cistern is beyond me. Not sure it will save anyone loads of money but it's functional and every little helps.
