Mermaid Condensator Alternative

I've been struggling with the Pacific Condensate Pumps in my boat being prone to failure. It was suggested to me to look at the Mermaid Condensator, but I thought the price was a bit outrageous for what it is, a venturi pump. So I did some googling and found something that looks suspiciously similar(I think it is exactly the same). It is a Chemical Injector made by Dema, model 204C ,the 1/2" NPT version, and is a fraction of the cost. It comes with 3 different orifices that are inserted into the bore.

My question, is anybody familiar with the Mermaid? My concern is the small bore diameter and the potential restriction to water flow that this Dema has. Is the Mermaid the same in this respect?

Finally I do have existing filters,but could use a source for new ones.

Re: Mermaid Condensator Alternative

It is the same device as sold be Mermaid as a "Condensator". One needs a check-valve in the up-take line for periods when the raw water pump isn't running. The check-valves are available from US Plastics for something on the order of $.50 each, or from Mermaid at $9.70 each the last time I checked (before I sold the damned thing--but with forewarning to the buyer). A small, inexpensive, "dosing pump" (E.g. see Tom Aquatics Aqua-Lifter Dosing Pump) discharging to a sink drain is all you need for a condensate drain, if anything at all.

FWIW...

Thanks for the info. I thought about just routing the drain directly to the bilge pump, which is literally just next to the AC Unit on the opposite side of a stringer.
