Many rainwater harvesting systems are fairly simple and easy to repair. Keeping your roof, gutters, and downspouts clear of leafs, branches, and debris is a must. Repair any gutter leaks right away.
If you employ any type of filter in your system, that filter should be cleaned regularly. Cisterns and storage tanks should be checked annually for leaks and in cold climates you may need to drain your tank for the winter to prevent freezing and expansion cracks. Storage tanks may also require cleaning at infrequent intervals.
If your storage tank develops a leak and needs to be patched, please consult the dealer or manufacturer to determine the preferred repair techniques.
If your rainwater system hooks directly into a sprinkler or drip irrigation system that may also require regular maintenance and repairs.
