Why Choose the Cruiser Services CS-40 Watermaker

First: “With Two Decades” of experience building and repairing piston pump Marine Watermakers, all this knowledge has been incorporated into Rich’s newest design (Cruiser Services CS-40 Watermaker).  All the parts, desired features and options to make a piston pump watermaker easy to operate and maintain come as standard features on the CS-40 Watermaker. 

Parts and features like:

* Stainless steel HP pump (STANDARD) -Rated for Sea Water RO
* Automatic Programmable Freshwater Flush
* Automatic TDS Product Water Quality Diversion
* Stainless Steel Pressure Vessel End Plugs (STANDARD)

Second: Rich’s experience cruising Mexico’s remote Sea of Cortez with his family and doing 7-Day-A-Week customer service and support have taught Rich the important lesson when it comes to using quality parts built within a robust overall design, Rich says:

“You can always find cheaper Cruising Gear based on cutting quality parts corners, but unfortunately, cheap parts have a way of getting expensive after international shipping, customs duties and local taxes, not to mention the Cruiser Truism of spending ‘Down Time-Down Island’ waiting for parts when cheap parts fail.  After years of cruising, living aboard and doing Cruiser Customer service, I’m a firm believer that you are better off buying quality at a fair price, from the start.”

Rich made sure that the automatic convenience features on the CS-40 have easy manual back-up capabilities, so that a simple timer or motorized valve failure doesn’t stop you from making water.

CS-40 Watermaker System Highlights:

  • Stainless Steel Pump with Ceramic Plungers purposely build for the harsh sea-water environment, by General Pump – the Off the Shelf industry leader in RO Piston Pump Manufacturing.  Rather than offering a cheaper standard pump to get the google search price clicks to our site for a later bait-n-switch, we start with and are only willing to use quality parts for something as mission critical as the HP Pump.  This philosophy flows through to our industry leading warranty.
  • Fully Programmable Automatic and Unattended Fresh Water Flushing from the on-panel controller powered by your ships DC system.  The controller allows you to easily “Set and See” the two important settings for watermaker freshwater flushing:
    Duration-length of the freshwater flush to adequately flush the system.
    Frequency-time between unattended freshwater flush cycles.
  • Fully Programable Water Quality TDS Meter and Automatic Product Water Diversion allow the fresh drinking water made by the watermaker to be continually monitored for quality and automatically sent TO or AWAY from your ships tank.  When the panel switch is turned to “AUTO TDS” the meter will monitor and send the water TO your ships tank once the water quality is below 480ppm and AWAY from your ships tank when it exceeds 500ppm.  These valves are also adjustable by you and of course our motorized stainless steel 3-way valve that the TDS Meter controls is able to be manually operated in the unlikely event of an electronics failure.  When the panel switch is set in the “MANUAL PURGE” position, the 3-way valve is forced away from your ships tank to either a waste location or as Rich prefers, to a water sample location at your galley or head sink.  TDS -Total Dissolved Solids- is a measurement of the drinking water quality, measured in PPM-Parts per Million.
  • Stainless Steel Pressure Vessel End Plugs are standard rather than anodized aluminum.  After years of seeing end plug corrosion issues that makes membrane change out difficult, Rich made the decision to just spend the extra money upfront for stainless steel end plugs. Rich has been overheard saying;

“This isn’t 1980 anymore, the internet is real and is the great consumer equalizer, the proprietary parts game Should Be A Thing Of The Past”

  • Freshwater Flush Layout that Includes the Boost Pump after seeing too many boost pumps damaged and even fail due to lack of fresh water flushing, Rich designed the freshwater flush circuit of the CS-40 watermaker to properly flush the mission critical components, including boost pump.
  • On-Panel Hour Meter to give you an easy indication of system maintenance.  Yes, it’s not an expensive thing to add, but little details like this help cruisers remember when it’s time for routine maintenance vs the reminder being a “Problem in Paradise”, as Rich calls it.
