Installation: FAQs
How do you link cold water storage cisterns?
Due to concerns about water stagnation which might cause the quality of the water to deteriorate the installation of inter-linked storage cisterns should be avoided wherever possible. Where it is unavoidable, the number of inter-linked cisterns should be minimised.
To minimise the risk of stagnation
The storage volume should be kept to a minimum
Cisterns should be connected in parallel
Any demand should create water flow throughout each cistern
Inlet and outlets should be installed at opposite ends of the cistern
Delayed action float valves should be used.
Metering of inlets may assist with balancing of turnover.
