Easier than most...but not simple. There is only one piston which makes for fewer seals.

I also already have the dedicated thru-hulls installed. I could very easily buy a CAT pump, a clutch and install them in one weekend.
If you have not already done your watermaker, http://www.rutuonline.com/html/watermaker.html is a very interesting and practical approach with the parts, etc....

Hello Trim,

I just ran across this thread and I'm wondering if there is a typo above.

According to Hydra Cell the F20X pump will deliver just under a gallon per minute or close to 60 gallons an hour. A 20 gallon per hour permeate flow would be a 33% recovery rate. That recovery rate seems quite high and still produce a low TDS.

I am a few days away from pulling the trigger on a F20X pump with a 2540 membrane or an F20E pump with a 2521 membrane. In theory according to Dow's ROSA software, neither combo will work properly. But, there are a number of published cases where an F20E and a 2521 membrane deliver 20% recovery rates with low TDS.

Dow wants at least 1 gallon per minute of concentrate flow out of the 2540 membrane. That concentrate flow can't be reached with a F20X pumping 1 gallon per minute in. How is your 2540 holding up with less than recommended concentrate flow rate?

Any further operational details on your watermaker is appreciated.

Very nice installation, BTW.

John

Here's a couple of DIY watermakers, FYI:
