We just had the October surprise snowstorm. Our power was out for 4 days. The rain that followed and melting snow meant that the Basepump HB 1000 had to run every 5 minutes to keep up with the peak water flow. It never missed a beat. The only negative was the loud water hammer when it shut off. I plan to add a water hammer arrestor to the supply line sometime. It is a great product that performs exactly as advertised.
I live at a bottom of a hill and it is a necessity to have a backup. When I moved into the home the owner installed this pump. My main pump died (didn't know it) and the water power back up kicked in and now it died. Fortunately I heard the alarm so knew it was running and not working. So I had to install 2 new pumps.
When I received this, I couldn't believe it was all plastic for the price I paid. But I went ahead and installed it anyway and I am not disappointed in its performance. It works terrific. It is loud as it runs and does cause water hammer at shut off but it does what it is supposed to. Just make sure you correct any high water pressure problems or you will get water blasting out from the head gasket when it shuts off. Also it is very loud because it is mounted right to the floor joist. I found out I need to install a water hammer arrestor to absorb the shock when water flowing in a pipe suddenly stops due to fast closing shutoff valves. The one time it kicked on because of a power outage overnight, it woke me up in a second floor bedroom, which when you think about it was actually a good thing so I could check on things. It is pricey, but it works. I just hope its all plastic construction holds up.
Bought this pump on recommendation from a friend. I lose power a couple times a year. I have used a battery powered backup pump for years, but it does no good when I lose power for a couple days. Plus there is the hassle of replacing the battery every few years. This pump installed pretty easily and works great. No more worries about how long my battery will last. Highly recommended.
I bought the backup pump 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 inch 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. I knew if I hired a professional plumber it would be costly, so I decided to do this myself. 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 review 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.
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-consuming 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 majority 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.
I installed this pump per the instructions and found I didn't have enough suction lift. Upon checking I found my city water supply to be about 60psi. I ran 20 feet of ¾ inch PEX off of the main line entering house. Initially I installed the ejector pump in the rafters and found it couldn't lift water the 10ft height that's because of my 20 foot PEX. I had to change the piping around and mount the pump down near the sump so that the suction distance is only a couple feet. Works now, but disappointed it didn't work when installed in the rafters. So make sure the water supply line is close to the city water feed for best results when it comes to city water pressure.
I selected the Zoeller 540-Flex based on the Zoeller's reputation. I am not a plumber. I didn't want to do soldering so I bought some shark bit connectors which just push and screw. I contacted Zoeller to get more detailed instruction on how to connect the float valve hose. That was confusing for me.
This is a great product, but it creates a strong water hammer sound. I found out I can install a water hammer arrestor to greatly reduce the sound. Beware that it takes a lot of water- one gallon of city water to pump out 2 gallons of pit water; but overall it is a great back-up solution. I was tired of bothering with batteries for a battery backup pump.
I like that there is no pump submerged in water because calcium forms when the pump is not used much. I found it more difficult to install this pump over a battery backup pump but the time it takes to install it is well worth the trouble.
I was tired of buying batteries all of the time and they are costly. I don't need a backup pump very much so now I can relax and not have to go and buy another battery.
These four water powered sump pumps work like all other water powered sump pumps. They work this way. 1) The float diaphragm acts as the sensor monitoring the height of the water in the pit. 2) The float diaphragm activates the ejector pump when the pit water reaches a predefined water pressure (pit water height). 3) The ejector pump valve opens allowing city water to flow and begin the suction process known as the Venturi effect. 4) Pit water sucks up through the suction tube caused by city water pressure as it passes through the ejector head. 5) The water thrusts through the discharge pipe to its destination away from the house.
