But the shower drain pump just replaced is in a very small sump, no extra room at all. Considering my inability to look at a replacement I chose like for like. If/ when this one dies (about 2 years historically) I'll see if there's a suitable diaphragm pump that fits. Here's a fun thought, most boats have these as bilge pumps, wonder now how my bilge pumps are doing. I normally flick the switch once a month and they make a noise. Now I'm wondering if they need a closer look. The advantage of the diaphragm pumps is that they are (usually) self priming - so only the pickup hose needs to be in the the bottom of the sump, the pump itself can be remote mounted wherever convenient.

Triggered by a feeling that the sea gods were sending me a message after 2 weekends in a row I was first vessel in attendance of slowly sinking boats whose average bilge pumps couldn't keep up with ingress. It has motivated me to upsize. I might even get a second one to give me 8,000 GPH. But hope I never need it. A bit like a life raft. But cheaper. In addition to an installed 4000 pump, I have one of these as a portable with a 3" lay flat hose for discharge Quote Link to post Share on other sites
Black Panther 1,523 Posted September 19, 2021 Author Share Posted September 19, 2021 Having seen the mess in the bilge after being inverted I would suggest nearly every bilge pump I've ever seen would clog in no time flat.. Quote Link to post Share on other sites

Absolutely right. Hence an easy clean strum box is needed... Quote Link to post Share on other sites

I really like the look of the Whale Gulper 220. Any idea if there's a supplier in NZ? 2nd choice the Johnson SPX - I couldn't see one on the marine deals website that looked like this - any idea of the model?

Fogg 427 Posted September 26, 2021 Share Posted September 26, 2021 Sorry, answered my own question. Whale Gulper available at Marine Deals too. Quote Link to post Share on other sites
