Howdy y'all, in my previous house (built in '96) I had a waterproofed basement with a sump that got a LOT of water in it. When it rained the pump would come on about every two minutes, and even a day after it stopped raining the pump would still come on about every 15 minutes. That neighborhood was also prone to power outages, so I installed a battery backup which really saved me a couple of times.

Now I'm in a slightly older house (built in '87) with a basement sump that gets less water in it. It apparently has a pedestal-style pump, because I can see the motor sticking above the sump cover. It comes on about once every 30-60 minutes when it's raining. Also, this neighborhood has buried power lines so power outages tend to be rare and short-lived. The sump pump looks like it's the original from when the house was built, and I don't see a check valve in the plumbing. This pump should probably be retired to the Sump Pump Hall of Fame, seeing how it's approaching 30 years old. Is there any reason I should stick with a pedestal-style pump? I have not taken the cover off, but it looks like a standard sump pit about 18" in diameter. I would like to take out the old pump, clean out the pit really well with my shop vac, and put in a submersible cast iron Zoeller pump and a quiet check valve. Can anybody think of a reason why that wouldn't work? I'm thinking about adding a battery backup pump too for peace of mind, even thought it's unlikely to be needed.
 
IMHO no new pump will equal the quality of the old pump. I would get a sump full alarm and a back up pump, battery and install it.

If it ain't broke then don't mess with it.

I'd buy a 2nd pump and leave the old one in place. The reason it lasted so long is reasonably pumping cycles AND motor is not submersed.
 
Can u have a 2nd pump in place as a backup? I would have a battery backup in place anyways, better than a flooded basement.
 
Perform a risk analysis. What is in the basement that would get ruined if it flooded? How likely is it to happen? What is your mitigation strategy?

I will have to perform the same for my sump pump. It's getting on 13 years old and we accumulated more stuff in the basement.

That is a good question. The current pedestal pump seems to be positioned right in the middle of the sump. I would probably have to change the plumbing a little and reposition the pump to make room for a second pump. I'll have to open it up and look at the current setup to see how much room there is.
 
The motor on the current pump will probably last forever, but the switch will fail. Its most likely a mechanical switch. You really want to get a pump with a non mechanical switch. For now I would install a water level alarm.
 
Just went through this and due to time (shipping) I had to replace my Zoeller M53's with two H2OPro pumps from Lowe's.
I have battery backup and replaced the incorrect 8-10 year old car battery with a deep cell Marine 27 size.

switch on one Zoeller was shot a long time ago so it was unplugged.
2nd pump's float must've hung up and we got swamped.
I lifted it and it pumped....but now they are all both replaced and we sleep better at night...well, we will once I replace the three check valves with QUIET check valves

good luck and remember redundancy is your friend. ,
 
I recently read an article in Fine Homebuilding regarding basements, curtain drains and the differences between the two types of sump pumps. You might find it useful.

Also, this was covered on Ask This Old House awhile back.

FH, Jan. 2015, No. 248 "What's the Difference? Sump Pumps: Submersibe vs. pedestal", pp. 30-32. Also a great side-bar on how to properly size a pump. Highly recommended.

The water is pumped outside to the backyard.


You may not want to put a check valve on it since it holds water in the pipe and could freeze up.
