HRO Seafari Escape Watermaker test?

I am rebuilding my watermaker with new gauges and pre-filter housing and I want to test it while docked in my marina. I was thinking of using 10 gallons of fresh water as the source water, filter it to remove the chlorine, and add some salt to test the watermaker and check that it removes the salt. It hasn't been run in a year except to flush it with fresh water weekly. Is there any harm in doing that and how much salt should I add to simulate sea water (approx. 35,000 ppm.)?

This is easy. Go to your local pet store that sells salt water fish. Pick up a bag of sea salt and a hydrometer. Mix the salt in un-chlorinated water (distilled works best) until you get your 35,000PPM. Route both the brine discharge and the product water back into your bucket and circulate andf measure the bucket to maintain the 35,000PPM and test the product water for flow amount and PPM levels.

Re: HRO Seafari Escape Watermaker test?

I'm always a little surprised at thought of not just running with the sea water under the boat for a startup/commissioning test run. As long as there is no oils floating in the water save the hassle and just run it and then toss out your $9 prefilters if you are worried about the nasty marina water. The solids will be filtered out by the prefilters and a short run in nasty water isn't going to hurt your RO Membranes.
