Why it matters
The 4TMS is a 4 in stainless steel submersible that draws from the bottom, so it can empty a cistern or tank lower than a side-intake pump. Wassermann rates it at 26 GPM and 138 ft of head from a 1/2 HP, 115 V motor with thermal protection.
It has a 1-1/4 in FNPT outlet and suits septic tanks, ponds, livestock water and irrigation as well as 4 in wells.
