Modular Watermaker​

Rainman Watermaker’s are ideal for installation, single motor configuration, hardware included. Take the stress and expense out of installation.

Each modular Rainman watermaker comes with a plumbing kit designed to cover most installation needs. However, since every boat is unique, you may need to source additional components such as a sea strainer, extra ¾″ hose, or specific fittings.

For those looking to fully install a Portable Rainman system, the plumbing kit is also available separately as an optional purchase.

We can install your Rainman Watermaker for you.

Installing a watermaker can feel overwhelming, but our experienced technicians make the process smooth and hassle-free.

Options

The Rainman modular system can be purchased and installed on its own, with only a simple valve/gauge assembly to control pressure. However, most customers will prefer to have the optional control panel and autoflush system to enhance the user experience.

Manual Control Panel

The optional control panel provides a remote management capability for your installed Rainman watermaker. It’s a highly presentable and functional add-on component that will ease the use of your watermaker. 

It is an injection moulded ASA acrylic panel that remains true to Rainman’s reputation of elegant simplicity. 

  • Integration with the Rainman autoflush system, triggers flush cycle after powering the watermaker off.
  • Built in tri-colour LED salinity sensor indicates when water is good to route to your tank.
  • Can be installed flush mounted in a wall, standalone with the included enclosure box, or even externally with the optional hatch.
  • Simple installation with no high pressure fittings or high voltage wiring.
  • Backwards compatible if you already have an installed electric modular or cased Rainman.

Autoflush

Your Rainman watermaker is a robust piece of equipment, but caring for certain aspects will prolong its life. Regularly flushing your Rainman with fresh water will maximise the life of your reverse osmosis membranes.

The optional autoflush system incorporates a solid state programmable timer that will flush your Rainman watermaker after each use and every seven days thereafter. It incorporates built in protection if your boat loses power during or between flush cycles.

Maintenance Requirements

While Rainman Watermakers require minimal maintenance, there are a few essential tasks you are required to keep up with, to extend the lifespan of your system. Our fully mobile and adaptable team is ready to help you take care of these, so you can enjoy fresh water worry-free.. Local Engineering provides expert maintenance, yearly service and ongoing support for your Rainman Watermaker.

When storing system:

  • Fresh water flush and pickle the system when storing it for more than a couple days. This may sound complex, but it is an easy five minute process with no specialist knowledge required. Alternatively, install the autoflush system to avoid the need for manually performing this task.

5-50+ hours of use:

  • Change the non-proprietary prefilter after 5-50+ hours of us, depending on cleanliness of the source water.

1-2 years:  

  • Change non-proprietary impeller in the lift pump after a year or two, depending on use.
  • Change the high pressure pump oil each 300 hours of use, using SAE-30 weight oil.

5-10 years:

  • Change the non-proprietary sized reverse osmosis membranes after 5-10 years.
  • If your system starts losing performance, the non-proprietary pump seals may eventually require replacing.
