Easy replacement By Diving The World on 12/11/2015Diving The World would recommend this product to a friendI just swapped mine out after a year of usage. I installed my pumps in a difficult to reach spot behind my sump which made these a little tricky to replace. I would suggest you mount your pumps where you can get to them easily. That said, they were not hard to replace.
