A follow up for anyone in the future with mechanical problems on their Sea-recovery unit.
1) Replacement membranes from SR are exorbitant IE $1200:00 EACH simply because SR decided to go for a unique diameter membrane, which is actually more compact space wise , in the long run it's cheaper to change over to a complete housing and membrane unit from someone like Cruise Equipment- Water and Power Solutions for Cruisers-Low Prices
2) The 'Energy Transfer Device' has 4 actuating rod seals
that by a system of valving receive the feed pressure (around 35psi) and alternately squeeze the raw water
through the membrane at around 850psi.
A replacement set will set you back around $450:00 however poly seals
are very available and i replaced them for $35:00..........
3) Feed pump that sends the clean feed water
up to the EDT are also available once you research
the codes, i replaced mine for $280:00 as against $1100:00.
maker is now running sweet, i was about to throw this one away but persisting with research
has saved us a shipload.....
