This is the Johnson Pump 22004, a heavy duty 12V DC bilge pump sold as a 2200 GPH model. It has two threaded discharge ports, one 1-1/8 in and one 1-1/4 in, and a removable check valve is standard. The motor is liquid cooled and runs on double ball bearings, with a stainless steel shaft and hardware and a thermoplastic body. It is built to ISO 8849 marine and CE standards.
Our take
The 22004 pairs a liquid cooled motor on double ball bearings, which the maker ties to extended service life, with a stainless steel shaft and thermoplastic body. A removable check valve is standard, and the 1-1/8 in and 1-1/4 in discharge ports cover two hose sizes.
From our buying guide
Rule and Johnson both say their bilge pumps are not intended for damage control. Flow falls as the discharge head rises, and the length of the hose, its bends and any check valve reduce it further.
Check before you buy:
- The maker's own table shows the flow at head, since how much a pump loses depends on the model.
- An automatic pump also has a manual switch, which ABYC's voluntary 2005 standard calls for.
- You'll fuse it to the maker's figure.
