|I bought one for filling/emptying my ballast setup. I emailed Attwood to see if they were submersible (which they are), but the Tech also noted they were not meant to transfer large quantities of water. |
So that got me wondering, how long do these pumps last for ballast use?
|I'd say that by "large quantities of water", he is probably talking about something quite a bit larger than 100 gal or so, like a swimming pool.|
|Oh, and I think I'm on my 3rd season on 8 of them in my boat. No problems.|
|No problems - great company to work with. They sent me hard to find fittings at no cost when I was building my ballast system on my boat.|
|the easy to access cartridge is nice too. in case you ever need to clean it. got some debris in there over the weekend (filling a starting pool, pump was sitting on bottom in 1' of water) it was cleaned out and pumping again in 15 seconds.|
|where can you get the fittins that attach to the aerator? |
i think they are 1 1/8". I briefly checked HD with no luck.
|fly high has fittings|
|The 1 1/8" is impossible to find other than what fly-high carries (look on buywake.com for fittings). |
I needed a specialized female threaded-to-hose barb and Attwood hooked me up for free. If you are building an internal ballast system, just keep that in mind.
