Happy Tanks Flush-Valves can be retro-fitted to your water inlet, at the water tank, to be able to flush-out waste that will have collected in the underground pipe-work. These pipes are often installed to carry the water from your down-pipes to the water-tank.

This "wet-system" is an area that often becomes infected with mould and bacteria, leading to taste and odour issues in your water supply. When Flush Valves are installed, we can thoroughly clean the pipe-work and avoid any further contamination of your water-tank.

  • Easy installation
  • Improves the quality of water entering the tank
  • Reduces maintenance costs


The tank sanitiser is a disinfecting and deodorising solution for potable water supplies. It is useful in the treatment of tank water when bacterial or viral contamination is suspected, or when the water has smells and requires de-odorising. It is ideal for the treatment of water tanks using a rainwater supply although is suitable for any tank water. It can be used as a one-off shock treatment or at a lower dosage for more regular use. However, we do not recommend it be used as an ongoing water treatment solution and it should only be used in tanks after they have been cleaned.

This is not a DIY product.


Underground pipes can become contaminated with waste from the roof and certain moulds and algae that can contaminate your water. After installing Happy Tanks Flush Valves on the inlet pipes to your water tanks, we can then treat the underground pipes with our Pipe Sanitiser that will kill organics and bacteria in the pipework. Once allowed to flush-clean with rain water, the caps are replaced on the flush valves and water can again be collected in the tank.
