Sea water strainer for watermaker

[Delfini]

I have recently started to fit a Katadyn 40e powersurvivor water maker and considering what type of sea water strainer to fit inline with the primary filter - as advised by the instructions

I am taking the input from the toilet sea water intake but not sure I want to install a plastic bodied device or more solid cast bodied type - any direct experiences or guidance for bulkhead fixed inline sea water strainer appreciated

A cast body type would cost a fortune presumably because they are for commercial craft.

I don't know whether the following links work? Anyhow if you go to ebay and do a search on "raw water strainers" you should get an idea of what is available.

A plastic one that you might use on your raw water engine intake would cost around $50

A cast strainer would cost $300+

Most installation manuals for watermakers insist that you use a dedicated inlet seacock for watermakers. The membranes dont like pressure shocks and that may be caused by a slight growth or obstruction in the inlet seacock, if you share the inlet for something else you may draw air down the pipe from the toilet. I would install a seaprate one or install a valve after the tee so you can close the toilet off when using the watermaker. that way you will save very expensive damage to the membrane(s).
