Ishipaco's Guide to the
PowerSurvivor  Katadyn 40E  Watermaker

The Katadyn Model 40E Waternaker


This website contains a collection of valuable information intended for owners and/or operators of Katadyn (or PUR) Model 40E reverse osmosis watermakers.

Included are tutorials on the installation, use, maintenance, and troubleshooting for a Model 40E watermaker, and a detailed video on the disassembly, Repair Seal Kit installation, and reassembly of the 40E.

Also included are the original Katadyn 40E Owner's Manual and a copy of the book I wrote about these watermakers in 1998. My book includes information on all of the powered models manufactured by PUR and Katadyn. Both texts are in Adobe PDF format and you will need to have Adobe Acrobat Reader installed on your computer to view them. If you haven't already installed the reader, you can download and install it for free from Adobe by clicking the handy link on the left. To do this, or to visit the Katadyn website, you'll need to have an Internet connection.

A Note About PUR vs. Katadyn Watermakers:  The highly regarded Swiss company, Katadyn, Inc., bought the watermaker division of PUR from Procter & Gamble several years ago. The physical construction of the more recent watermakers made by Katadyn is, for all practical purposes, the same as the original PUR models, with this caveat:  Katadyn has corrected some original PUR design problems to improve performance. The information on this website applies to Model 40E watermakers from both PUR and Katadyn. Where features differ they are duly noted. For more background on this topic, click the "PUR/Katadyn Information" link on the navigation panel on the upper left of this page.

Please help spread the word about this website!

I strongly encourage you to help me get this valuable information to your fellow cruisers. If you have a website, consider installing a link to this website. When you're having a relaxed conversation over a cold drink and the subject of watermakers comes up, let your friends know about this online resource. Finally, if you can't find the answer to a question you have about your watermaker, send me an email at powersurvivorhelp(at)ishipaco(dot)com and I'll try to help you. Thanks in advance.
