Review: 6 years later - still Impressed ! - I've been running this pump (ET-80) in my small 1/10th acre pond for 6 years now. It runs constantly in the summer. We have it sitting on a gravel base and covered by a decorative rock cover. We have never once brought the unit 'in' for the winter, yet when we plug it in at the beginning of each summer, it starts right up and begins immediately, moving a decent amount of water. Over 6 years, we haven't noticed any degradation. THIS PUMP HAS BEEN GREAT !!! We have it at about 7-8 ft depth and use a weighted air hose along with a Rootscape Bubbler. Truly excellent combo. We recently finished a larger (1 acre) pond and I'm looking to add the same pump to that pond. I'll have to do research to see if the unit can still push air properly at 15 ft depth, and with a much longer air hose... or I may have to step up to a larger pump (maybe the ET-120). If you have a pond, do yourself a favor and buy the ET-80 with the Rootscape Bubbler. Neither of the companies sponsored this review, but I'm just a truly impressed buyer/owner. 6 years is a good test! I'd be happy to respond to any Q's or comments, from Buyers or the company.
Review: 6 months running strong - same noise level as previous pump and has continuously worked for past 6 months. No complaints here.

## Questions & Answers

**Q: does the ET80 come with a 15A prewired plug for 110 volt service?**
A: It comes with a normal plug. 3 prong that you could plug into any outlet in a normal US home.

**Q: Will this pump replace a hiblow 80 series?**
A: This pump I used to replace a hiblow 80 series, in September 2017, & I haven't had any problems so far. The Blue Diamond seems to work just as well as the more expensive hiblow. I would buy the blue diamond again.

**Q: I have a hoot system with a troy-air h500a pump and it has all the alarms.  does this pump have all the same hook ups for the alarms?**
A: Blue Diamond makes these pumps two ways, "with brass" and without.   The "brass" is a small threaded connection that is included with those pumps marked "with brass".  Those pumps also have a screw on the bottom that can be removed so that this brass valve can be threaded in.  If you buy from us, please indicate that you want one "with brass" and we will make sure you get it with the alarm connections.  Sincerely Nate at Practical Garden Ponds 484 356 5351

**Q: I have a cajun aire model# 500, 500gpd, class 1 with the hem-la80. Will this et80 work with my system?**
A: Not sure but I am using it to replace my hoot septic motor
