My pump died. Jabsco
31750. I don't remember if it's a variable speed pump, pictured here. 3.5 gpm maybe. Was decent.
Was reading this thread and stumbled onto a 24v jabsco 36900 belt diaphragm
pump that was new in the box for $100. Someones spares, seller must not have know or cared what it was. Still had caps on the nipples. 4.5gpm 20-40psi pressure switch.
After install, it's quiet. Quieter than the old one, with more flow. Takes more room though. I can hear it when it runs a little bit, but it's like a quiet tick tick tick noise, very unobtrusive and hardly notice it.
I had other types of these belt drive pumps for the bilge
but I took them out when I switched to 12v. Simple, known for longevity and have rebuild
kits. Wondering if I can use one of these for a water maker boost pump and the toilet, the toilet pump is crazy loud.
