How I Installed a water powered backup sump pump. Liberty SJ10

- Опубликовано: 18 июн 2024
- This is how I installed it. It works as a back up to your regular sump pump. It is powered by water pressure from your public water lines. People with wells are unfortunately out of luck. About once a year my basement floods because of the sump pump not running. I used pex because it was easier to fit behind the furnace and other things in my basement. It’s also cheaper than copper. Although I would have used copper if I could. That first valve I soldered in was solely because I don’t trust pex for the long haul, but figured it should be good enough. Other people may install it differently. That’s my disclaimer. Please add your comments about your own sump pump adventures.
----Update: April 3, 2024. Our power went out for 23 hours during a storm. The new back up pump did work and is happily pumping water out and making me breath a sign of relief. To my surprise, it did NOT MAKE A SOUND. It was absolutely silent. I didn’t even think it was on until I went outside to see the water being pumped out. The basement stayed dry.

Depends on your code but in our area you could tie it in... just have a check valve on each pump.
Good video, we install a lot of the SJ10's when our client has city water. The unit does come with a built in back flow preventer. NIce job
Thank you.
Very helpful and well-edited video. Many thanks for putting this together!
Thanks.
Thank you for taking the time and making this video. I was actually looking for an instructional video like this to use as a reference and inspiration.
Thanks for sharing your vedio sir watching from Canada 🇨🇦 😊
Thank you, amazing explanation ❤❤
EXECLLENT VIDEO, will use pex to do mine now, plus all the valves thanks
Thanks. I only expect it to only run once a year or so, that’s why I used pex. If it ran more often, I would have spent the extra money and used copper since that’s much better overall.
TY
Very good video. I am going to order the same parts you used from Home Depot. Can I ask what diameter pex you used? Thank you.
It’s all 3/4”. The pump is made for 3/4”. Some of my parts were from Home Depot, others were Lowe’s. All of the brass fittings are SharkBite.
@@circusitch Thank you!
I am very interested in this product. Can you tell me why I cant find a local plumber with any real experience with these pumps ? They appear to be amazing, So why are plumbers not putting them in all over? Thank you.
Beats me. You’d think it wouldn’t be a problem. I once knew an HVAC guy who did it. But if you find someone, I’d say make sure you can trust them to do it right.
If you shut off your water when you're away for an extended period of time (like you should), be sure to make your tie-in before the main shut off.
That’s a good point. I did not do that. But I’m also never away for extended periods of time. If so, I’d consider redoing the connection.
why can't you use the same (existing) discharge line of the main pump? is this a municipality restrictions or the pump manufacturer recommendations? Thanks!
I don’t know if it’s local code or whatever. But that’s what they say. My guess it’s so no water will discharge through the actual sump pump.
@@circusitch got it. Thanks
If the main pump discharge line freezes, the main pump won't be able to push water through the discharge, filling the pit. The backup will try to push more water in (at a much higher pressure) which would blow away fittings and flood the basement.
@@phill8008Good point. The way mine is, freezing would never be a problem. But I’ve seen other houses where it could be.
Why can't you tie into the discharge pipe from the electric pump ?
They say not to. Probably so it won’t go back through that pipe into the existing sump pump. Not everyone has check valves.
I connected to the existing pipe using a "Y" fitting with no issues. This must be a local code issue?
Could be. But it’s probably because if there are no check valves, big trouble would ensue.
@@circusitch Of course, you have to have a check valve for the main pump, and there is a built-in check value for the Liberty pump.
@@gordd7348 The big problem would be if there is no check valve in the original sump pump. Then you’re be blasting tons of water back into that non working sump pump. And not everyone has a check valve.
can you say why you are not allowed to use the existing pipe and is that a local code or universal?
I don’t know who made that rule, but it’s meant to keep the discharge water from going back down into your sump pump. Not everyone has a check valve. But even if you do, it seems like a good idea to have a separate pipe. No matter how much of a pain it is.
thank you @@circusitch, I am referring to where you state it's not legal to use your main sump pump's discharge pipe out into the back yard. Wasn't a question about the check valve which makes sense. I don't get why you could not use the existing pipes and where the risk lies with that?
@@AjayboFrom what I read, and heard, it is what I said. I’m not sure about the codes or legality. But it’s just smart to run a separate pipe. Also, it is illegal to run sump pumps into your normal sewer line.
@@Ajaybo From what I remember they suggest that a separate discharge pipe be used so that you will quickly notice when the backup sump is being activated and also in case the original discharge pipe is the problem (perhaps plugged).
@@circusitchyes, and each pump can be serviced individually while maintaining sump drainage.
Why not link into the existing discharge pipe?
They say don’t so I didn’t. Although it’s rare that I actually do follow the rules.
doesn't the SJ10 have a built in check valve?
It does but I added one anyway.
