Coralife Energy Savers ACL76004 Water Pump 100gpd Ro Unit

After initial assembly, there was a small leak on the back. I wanted to wall mount the unit, but the leak prevented that. I worked with an ESU (the manufacturer) support engineer to resolve the problem. I cracked a part following his instructions, which made the leak worse. The engineer sent me a replacement part that did not fit. At this point, I gave up on asking the manufacturer for help.

Finding a replacement part that fit was a major hassle as the instructions don't include any sort of part list. Finally I located the part and replaced it. No sooner was that leak fixed than the increased pressure (from no longer leaking) caused another part of the unit to leak. By now the filter is out of warranty and I have to set it up on top of the washing machine so water doesn't go everywhere. Every time I use it, I'm tempted to throw it in the trash.

Instruction are not very good. Drawings are fine but don't clearly show things such as which way filter units go into the canisters, or how to set it up for an open reservoir. The instructions need to explain more about how the unit actually works, such as, which valves do what, etc. This information was not available at any of the web sites I could find. This unit does not include enough tubing, or tell where to purchase longer lengths, or what type of tubing to use. I had to purchase more tubing from a local hardware store. It took a lot of research and improvision and I had to buy a special float valve to set up to store water for aquarium use. This unit is advertised as being used for aquarium setups and is sold by aquarium vendors. It should explain how to set up for aquarium use, but, does not. Unit seems to work fine, now, but, I am very disappointed that it took so much effort to set up, and I am an equipment maintenance technician who deals with all sorts of complex equipment and knows how to install highly technical stuff. I would not call this highly technical, but, the instructions give very little help in understanding this piece of equipment and how it works. This unit, for this reason, gets a low rating from me. I purchased this unit because it has a high daily output and uses a pressure pump, which reduces water wastage.
