Customer Reviews
I installed this backup sump pump about a month ago, and thought I'd wait on a review until it had actually seen some duty other than testing. My wife and I purchased this house late in '09 and it had only a primary sump pump, which we imagined might become a problem during power outages. Our primary pump runs regularly. I looked at the battery backup pumps and Lowe's and decided to look around some more, and decided that water-powered ones would be a better way to go. It's an emergency pump, not primary, so the water loss during operation didn't concern me.I went with the Basepump model after reading positive reviews here and elsewhere. After running their tests (water pressure, GPM in the sump, and the bucket test) I went for the smallest model, the 750, and it turned out to be a perfect match. I also chatted on the phone with an employee who was very friendly and knowledgeable about the unit. The pump itself is small, and all of the fittings and housings are plastic, but seem durable. I don't have any reservations about the quality. I think the unit is a tad pricey, but compared to the cost of having water in the basement, it's negligible.I installed the unit myself and didn't run into any problems. I have an unfinished basement which definitely helped. It comes with only one small mounting bracket, but since I also ordered the heavy double check valve for the incoming water line (threads between the water supply line and the Basepump), I wanted more support. I found a 1-1/2" conduit hanging bracket which I put around the double check valve to hang the unit from the side of the joist. A 1/2" water line ran nearby, but it went through quite a few tees and turns before getting there, so I ran a new dedicated 3/4" copper line to the Basepump. The PVC discharge runs outside, then straight down into a 45 and angles out from the house about a foot. After some tweaking of the pump's "timer", a pneumatic flow control valve, I achieved the recommended 30-45 second pump running time after the yellow float drops down.Back to the operation - I'd tested it during installation but otherwise it had not seen any use until last night. A storm blew threw and caused a power outage for four hours. I was awakened when this occurred, so I went down to the basement to make sure the Basepump would begin to do its job. I was happy to see that it performed flawlessly, running often during the power outage. It is definitely not as powerful as our primary pump, but as an emergency unit it is perfect. Not having to worry about batteries running down is well worth it in terms of peace of mind.So five stars for now. I'll update this later if necessary.
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.[...]
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.
I have two of these as backups for sump pits in my basement. Normally there's no problem down there, but sometimes the weather isn't normal. Like when there's a tropical storm, for instance.I considered several solutions for a last line of defense against flooding, and finally settled on this one. I liked the first well enough to buy a second about a year later. There could be some economy of scale with plumbers if all pumps went in at the same time - more on that in a moment.This pump works on water pressure from your house's cold water line. The pressure in that line needs to be reasonably good; the principle then is the same as using a jet of water from your garden hose to push water up a slight incline - if you have enough pressure, you can use water to push other water upward. This pump acts that way, but much more efficiently than the garden hose example because it's a closed system.You add the float for this pump to the existing sump pit; there should be an electric pump in there already; the float for this pump goes in the pit/bucket above the electric pump's float. Therefore, this pump won't fire unless the electric isn't working. For instance, when there's no electricity. This pump connects to the existing sump's exhaust / discharge pipe, it connects in one spot for intake, that line goes up to the pump, and then it connects again higher up for discharge into the existing discharge pipe. Valves keep the water moving the correct direction. This pump is also connected to the cold water feed from the house, and when it's working it pushes a lot of water - which is fine, I'd rather write a check to the water company than vacuum it out of my basement. The connections have to be leak-free, of course, and they're not exactly easy. There are some kits for sale by this company but I just went with a plumber's install. The pump should be adjusted for how long it will run, etc, via a small knob on the pump. It's ugly - you don't want it anywhere in finished space if at all possible. There is also a connection tube from the pump to the float, this activates the pump when the float is high enough. This connection tube should not kink and should be kept away from traffic areas - it's rather delicate and persnickity and should basically be left alone once in place.Why did I buy this and not a battery backup system? Well, I feel better about this solution because there's no battery to run out. As it runs on water pressure, as long as there's water pressure it can work. Those with wells and independent systems please make a note of that. Also, electric pump / battery systems draw a lot of amps when they start up, and batteries have to be recharged, changed, et cetera. I just didn't want to deal with that business. I test these two pumps once or twice a year by unplugging the primary pump and filling the sump pit with a garden hose; other than that maintenance I don't worry about it, and I don't worry about my finished basement flooding when the power is off.
I just had this installed by a friend. Really all you need is some good planning and some experience soldering copper plumbing. I had a plumber tell me these weren't any good but I have a feeling they have experience with the really cheap versions sold at places like Home Depot. And they happen to prefer the battery based units they sell for almost $3000 installed. Go figure.Pros:1) no battery needed, purely mechanical. Batteries also normally need to be replaced every 3-5 years so no worry about that here.2) I'd rather pay extra for water than have water in my basement3) can be away from home for long periods of time without worry4) great instructions, fairly easy to install if you plan aheadCons:1) Loud when shutting off but this can be an indicator of when it is running. (Can also install a water hammer thing - don't know the exact name).2) Needs to run 1 full minute before the air gets sucked out and water is actually evacuated.3) effectiveness depends largely on your water pressure but this makes sense.I just don't know why people have hardly heard of these. I saw this on 'This Old House' at least 10-15 years ago. I can't find any negative reviews either. 1 person complained it ran and ran because his main pump failed and he didn't know it was running. He ended up with a fairly large water bill. So... it was working and he never checked his basement? I don't know to me that means it works even for long periods of time which it wasn't meant for. And it's the owner's responsibility to install an alarm so you know when it's in operation.I think 'con' (2) can be taken care of by a dual-check valve to keep water in the vertical discharge pipe (so it doesn't fill with air) but I don't know if the suction is enough to actually open the valve. I'm not a plumber and don't have enough experience with these valves. As it is, it works great given the 1 minute of sucking air, but again this is a backup and hopefully will never be needed.If you set this up right I think you will sleep well at night knowing it is there.
Installed Basepump in April 2010. It took about 4 hours most of which was consumed by running copper pipe to unit. I just had the first power outage recently and it performed just as advertised. I am very happy that I can be away from home without worrying about my newly remodeled basement having water in it. I have recommended this product to friends and family.
Now that I look back at my situation with my sump pump setup, I don't know how I would live without the basepump. This product simply works! After looking at battery backup sump pumps, concrete cutting options, barrier/dam creations, and all other ideas myself and others came up with, this gem landed in my lap. When the power goes out, what is the one thing that in most cases still works? Water.... or water pressure to be more specific. This item creates suction using water pressure, and let me say it creates really good lift. After contacting some plumbers for a install quote, I decided to install it myself. The package contains almost everything you need, minus some pipe and a few fittings/glues. I would say I spent around $50.00 in parts, and it took me around 4 hours total to get it in. I unplugged my main pump to simulate a power failure and waited until the water level put the water powered sump pump into action. At fist I barely noticed the unit running, it is super quiet. It also pumps alot of water out, I would say just as fast as my main sump pump. I now sleep alot better when a hard rain comes down, knowing that I have my main pump, my backup basepump, and two flood alarms downstairs keeping my basement dry. My question always was, what keeps your basement dry when the power goes out for a extended period of time, and you are NOT home? The answer is basepump, a water powered sump pump. Don't think about it, just get it.
