Well
.. I am not sure if this is a recommendation or not
.LOL
I chose to use a Danner Supreme Classic magnetic drive utility pump, Model 7 (700gph)
This pump seemed MUCH better built than the Eco-plus line
..If you choose to use the Eco-Plus, be aware of the multitude of inlet and outlet sizes and differences on the same pump. The Eco-Plus 396 is the only pump with ½ inlet and outlet fittings. The Danner Supreme Classic has both a ½inlet and outlet on many in their line.
The face plates on both the Eco-Pump and the Danner Classicare NOT made for screwing fittings into! Be EXTREEMELY careful when screwing in your fittings; do not even come close to over tightening! I split the outlet on an Ecp-Plus
. Purchased a Danner and then proceeded to split the inlet on that one also!
Should you purchase a Danner Supreme Classic, also purchase a spare faceplate
.. After getting my second Danner pump set up, after three weeks the outlet housing (not the threaded part but the housing this time)cracked
. Created quite the little fountain in my hydro room (with no drainage I might add). What a freaking mess!!! I believe I am going to run my pipe through a Uni-Seal and into a 5gal bucket to house the pump in an effort to avoid future catastrophes
..
So
.
Eco-Plus Cheap, burns out quickly, poor build quality
..Buy a spare!
Danner Supreme Classic Much better quality, weak faceplate
.Buy a spare faceplate!
Best advice I can give
Prepare for catastrophic failure.What would happen if the entire system was pumped out onto your floor overnight?
Side note: As far as pump size, I am using a 700gpm pump on four 27gal buckets and a reservoir. There is a good 1 ½ difference between the first and last bucket. I think a 500gal pump would be more than adequate in this system.
Now I will re-ask the OPs original question
..Does anybody know of a GOOD 500-700gph inline pump?
