options for rigid plastic containers for sump

[wickette]

Interesting, I have read in a few places that food safe HDPE is less likely to leach chemicals.

My point was even when an HDPE container is not rated 'food safe', over 99.9% of the time it wont have any more leachables than an HDPE container that is 'food safe'.

HDPE is a very tough plastic, even if there is impurities in it, it should stay locked in the HDPE, no leach into water.
