Excellent Backup System (I would not suggest this as the primary).
5 Stars
Excellent Backup System (I would not suggest this as the primary).
When I lose power to the house, it usually happens because of flooding in the area. Though my battery backup system was fine for a short period of time, and I if I would have time to get my generator running for long outages, this system removes those limitations. This will need no human intervention even when we are without power for an extended period of time.The system works as advertised. I would not use this as my primary pump because it uses public water to run, but it's an excellent choice as a backup.I still have to cover the pit because I have a radon issue, so you can ignore the large white pipe.I added a water hammer arrestor and a fill valve so I can test it, so you can also ignore all the blue pipes too.There is a one-way check valve for the water supply. That check valve is not necessary per the instructions.There is a discharge check valve on the primary pump, but per the instructions you do not install a check valve on the JetPump because it's unnecessary and would reduce performance. Re performance, I used 45 degree turns rather than 90 degree turns. If you don't have space, I don't anticipate using 90 degree turns would be an issue, it would simply be less efficient. I had the room, so I opted to maximize efficiency.The only expected negative is that it will require more physical space in the pit, and I will have to work on how best to seal the pit because of the radon exhaust pipe. Since I have the room, I will simply be building a box around the entire thing and using roofing rubber grommets around the PVC pipes to help make a good seal.Again, excellent Backup System, I would still use a traditional sump pump for the primary system.

4.0 out of 5 stars Works fine, not the easiest install
Reviewed in Canada on February 26, 2013
I spent quite a few hours configuring the pipes for this sump pump. First, it's quite a tight fit. My only complaint is that the unit could be a bit more compact. The length of the discharge pipe could be manufactured shorter to give more room to install the pump lower in the pit. Or, the intake pipe and floater switch rod could be lengthened. (I like as little water in my sump pit as possible.) Even as low as I've been able to install it, there is a good 5" above the activation point of the conventional sump pump, before the back-up kicks in. I think this is higher than it could/should be.

Second, since this unit is secured to the discharge pipe of the conventional sump pump I found it quite challenging to cut and fit all the pipes. There are essentially three points that need to align nearly perfectly: the discharge pipe of the back-up pump to the main discharge line, the mounting point of the back-up pump with the conventional sump pump discharge pipe, and the copper supply line. There isn't a lot of room for error. And, since the water supply uses a SharkBite fitting you need room to maneuver it into place. That's difficult with so many ridged connections.

After having done this and now understanding the difficulties, I would highly recommend using flexible PEX tubing instead of copper for the water connection. This will make installation infinitely easier.

Also, if you use ABS pipe like I did, you'll need to use ABS/PVC transition cement to connect it to the PVC of the sump pump.

Finally, make sure you add a rubber coupling to the conventional sump pump discharge because you'll want to replace that pump some day and you won't want to cut the whole mess out to do it.

All this said, the pump works just like it's supposed to. And, it's rather quiet to boot. Great peace of mind.
