[RE-wrenches] TIny House Pump

[Ray Walters]

Yes,  I've definitely used the Dankoff Flolight before.  I've seen them 
last over 15 years.  Cost is higher than the Grundfos though.
I'm dreaming of something in the $200 - $300 range.  Basically a really 
beefed up Shurflo, or dumbed down Grundfos MQ.
