OK, stayed up last night and got high on PVC cement fumes putting a first-glance thing together...works great! I used two PVC unions on my inflow and outflow pipes so I can disconnect the pump easy, (and prime easy). It does require priming, but that wasn't hard....and it fired right up, pumped away.
So far I'm into it for $53. 37 for the pump after tax, plus a 2.50 lowes bucket, PVC, extension cord to cannibalize to wire it, etc. takes me up to $53. I think I'll swing by Northern Brewer and get some more disconnects so I can have it pump through the gas and liquid posts at the same time as it sprays up into the carboy....it certainly has good flow though, even with the restrictions from the PVC unions...
My eventual plan is to have a hose with a union attached to it that I can hook to the input at will, allowing me to flush each keg with fresh water after oxycleaning without removing oxyclean solution from the bucket. I'll work more on it tonight, and hopefully get enough done to post pics.
