Thanks Kev - that's really helpful!QldKev said:That's the one.
I'm glad I went the mp-20 over the mp-15, but that requirement will depend on yor build. If you don't want to recirculate wort back at the heating element and only want a pump for a single brew sized system the mp-15 would be heaps.
Not much has changed since that review, it's still running no problems. It does still take a lot more to prime than the March, but once it's started all is ok.
I don't run either the kaixin or march pump any hotter than mash out temps, so cannot comment on usability above those temps. They both run perfect at 78c.
The kaixin pump probably does vibrate a bit more, but I just sit it on some leftover camping mat to get rid of any noise being transferred into the table.
Maybe it could be worth while putting post in the kaixin thread asking if anyone has had any reliability issues with the kaixin. My one has not had any issues. If there has been no dramas with other peoples kaixin pumps I think thats the best value for money option.
