We recommend you use a professional tank cleaning company to do this. A professional tank cleaning company is able to vacuum the base of your tank without emptying the water. Happy Tanks can clean your Tank if you are in the Auckland and Northland regions. We recommend a Google search to find a local cleaning company for your area. 

If you would like to clean the tank yourself, please see the links below for instructions on how best to do this.

Alternatively, you could consider installing a Tank Vac. These will remove build-up of sediment already present and help keep your tank clean all the time.

Yes, a Wallace Seal can be used to seal the pipe to the tank. It is important to note that a Wallace Seal, not a Uniseal, should be used as it has a deeper throat to seal inside the corrugation and is more malleable. We recommend installing the seal no more than 500mm down the side wall of the tank.
