Whilst your Waterwall tanks do not require a lot of maintenance, there are steps to keep the tank operating effectively.

The best times to check your tank is before and after the first rain of the season, and then intermittently during periods of rain.

The following checklist is supplied with each Waterwall Fatboy tank and can be downloaded here.

Roof catchment – check roof for debris or loose parts that may end up in your tank. Remove branches overhanging gutters.

Gutters and downspouts – clean gutters, removing leaves and debris. Check for holes and leaks.

Rain heads, first flush diverters and filters - remove rubbish collected in any filtering devices. Clean and flush out filters, check they are operating correctly. Clean leaf guards and mosquito screens on rain heads.

Inlet and overflow – clean inlet strainer and overflow throughout periods of rain, keep free of debris.

Pumps and taps – check for signs of leaks. Tighten fittings or use anti-leak plumbing tape to ensure a tighter fit.

Check for signs of mosquitoes and larvae - adding a layer of liquid paraffin to the water will suffocate larvae. Find and close gaps which may allow entry of mosquitoes.

Tank footings and fixings – check for structural integrity.

Monitor water quality – it should be relatively clear, with no taste or smell. If sediment level is high you may need to drain and flush out the tank with a garden hose.

Freezing - as with all water tanks, the Waterwall Fatboy should be emptied and the outlets left open during periods of freezing temperatures.
