• Some homeowners have had infiltration problems. What was done to correct them?
    Cracked riser/tank lids were replaced, some risers had uneven edges (due to installation issues) trued -up so the lids and lid gaskets could seal, and joints between the risers and the tanks in some cases were leaking due to failed epoxy. These failed joints were either re-epoxied or an inert impermeable clay (Bentonite) was packed around the joint to seal it. All tank lids need to be left uncovered (no dirt or plantings) therefore visible and the gaskets of the lids need to be intact. Water should be diverted from risers and not be allowed to pool around the lid areas. This limits potential flow into the tanks via the riser lids.
