I am considering the following: I have a Spectra Ventura 150, manual unit (no MPC controller), that has a seawater strainer and 5 micron filter before the Spectra Jabsco
. There is about a 24" head
(give or take a few inches, I'm off the boat
for a bit) from the through-hull to the feed pump head
. I installed a rebuilt Clark pump from Spectra about 2 years ago and replaced the feed pump head about a year ago. Output has been around 5 gpm or less, and no higher when voltage is up. Water
quality has been a bit variable, and I am planning to replace the membrane (it is at least 7 years old). When I sent in the Clark pump for replacement one of the cylinders was scored.
I'm considering the following: in-line between the sea water
strainer and the 5 micron filter housing, adding a 20 micron filter housing and a booster pump of some sort, in that order (so it would go thru-hull, sea water strainer, 20 micron filter, booster pump, 5 micron filter, Spectra feed pump, Clark pump).
Anyone (Tellie?) have thoughts or experience with the foregoing? Thanks in advance.
