I am a bit out of my general knowledge zone ... bought a small lake house three years ago so still learning in-outs of winterization (Smith Mountain Lake a bit south of Roanoke, Virginia).
I drained the pump for the winter, but had previously noticed stress cracks in the iron pump housing probably from previous freezes - this year it leaks water across an 8" crack likely due to much colder than usual and inexpert draining :-( ... it is a Sta Rite HMSF-1FL, horizontal pump with a 1 1/2 HP motor and pressure tank - was used by previous owner for landscape irrigation (300 feet uphill with 75 foot elevation increase above the pump) and for general dock and boat cleaning with two faucets. The system is mounted on a platform about 10' above the usual lake water level. The pump cycles on/off very quickly with just water hose on the dock running. I like the pressure, but sense I am way over motored with 1 1/2 HP.
The irrigation system was both unnecessary and long ago abandoned.
I would like to simply replace the housing, but the motor and pressure switch are original (probably 15 years old?) - and, I can't find much on line related to this procedure - looks like you prise the motor away from housing a bit and spin the rotor out of the vane assembly). A new pump/motor/switch is pretty expensive, and may now be significantly oversized for just the dockside clearning and one additional faucet about 50 feet away at the same level as the pump.
I don't want to change out the suction line or modify the pressure lines - too much of it to economically replace, but could use reducers, etc, if a smaller pump with different in/out line sizes made economic sense. If I did replace the entire system (except the tank), I would like to keep the location the same for wiring and line connections.
Thoughts on most reasonable course of action?
Thanks!!
