Im wondering about the dependability of the Jabsco diaphragm pump over the sealand bellows T pump.... I know the sealand pump is among the top rated discharge pumps available, but it seems the jabsco pump has not been on the market as long so there is not as many reviews to scan thru to get an idea of what to expect from it.... in the past, I have used a Whale Gusher10 manual diaphragm pump on an offshore fishing boat for several years to discharge (when we couldnt make it back in time) without any problems...ever. but the jabsco electric is NOT a whale gusher, but its still a simple pump, and a lot more affordable than the sealand t pump.... thanks for any info you may be able to offer...
