5.0 out of 5 stars Great product, works as advertised, October 15, 2007

By	Kristian Burkhardt (Chicago, IL United States) - See all my reviews (REAL NAME)

I bought this product in Oct of 2007. I bought the version that goes inline on your current sump's discharge pipe.

It came 90% preassembled, so there was very little assembly work to do other than the actual install.

The install is straightforward, but time consuming. Cutting a section out of the PVC discharge pipe and installing the basepump was easy. Running 3/4" copper pipe to feed the basepump took me about 4 hours, but I'm a novice with plumbing, and this was my first real plumbing job.

Now that it's installed, it works great.

One recommendation I have is to install a water hammer arrestor near the pump. One of the other posters recommended it, and I did it, and I'm glad I did - the pump shuts off pretty suddenly and it would have been really loud without the arrestor.

5.0 out of 5 stars Works GREAT - amazing product, June 30, 2008

By	Caseybea (Greendale, WI USA) - See all my reviews

OK, so when I installed my primary sump pump a year ago, I thought about a backup-- but, didn't think much because my crock BARELY drips, and we live in an area with little or no power outages.

Whoops. 3 weeks ago we had a massive series of storms, and our crock went from drips to a steady stream of water pouring in. Oh yeah, and we lost power for SEVERAL hours. Fortunately, this time we were home and sat by the crock and bailed. And bailed. And bailed. TONS of homes in our area had flooded basements.

The next day I ordered this unit, the RB750. Even under the worst conditions, this version rated way above the max water we ever get.

Set aside a good day for the installation- the plumbing takes the longest (considering you need a new valve, union, a few elbows, a "T"). I am skilled at plumbing, so the installation for me was relatively easy - just time-comsuming because you need to take care to do this RIGHT.

When I hooked it up and fired up the water supply, I have to admit that although I was a bit skeptical, my attitude quickly turned to amazement because this thing works GREAT. As a test, I unplugged my primary sump pump and started filling the crock with water. *click*. *whoosh*- and the pump turned on and instantly started sucking water. I did some measuring and this thing emptied about 3 gallons out of the crock in 15-18 seconds, which actually does match the rating of the unit (750 gallons an hour).

Some people complained about "hammering" (loud noise) when the pump shuts off, I didn't notice it that much but we have arrestors in other parts of our plumbing. I suspect this is more prominent in the bigger model (RB-1000).

Despite the majoity of the parts being made of plastic, I highly recommend this as a backup system for your sump pump. One afternoon and the install is done-- and no maintenance required, no super-expensive batteries, etc. And it works quite well.
