Welp, I have it this time, I bought a house and the sump pump now cycles every 30-45 seconds. Whoa.

I decided yesterday to pull the existing pumps (which look old as the hills) and replaced them with Liberty 237 pumps. I doubled up as they did, and replaced the check valves as well. I *currently* have one about 2" higher than the other more in a 'backup' style of system. Water pours into the crock like crazy...and unfortunately it's only a standard size crock (I'm not there and forgot to measure it, maybe 18" diameter?). The liberty 237 is cycling every 30 seconds, then runs for 10 seconds. That's obviously crazy town in my book (it's been a wet year, but it's not THAT wet).

My question is two-fold. I have looked at the Liberty Pumps 5050, which is a 'duplex' control. I don't know if I can still use the Liberty 237 in conjunction with that control or not? And if so, I believe they use their own 'switch' which appears you can allow it to have more depth range to allow the pump to run longer and cycle less?

Anyone use a setup like this with any luck? I clearly want as much protection as I can as it's a semi-finished basement. Any other thoughts on getting the pumps to not short-cycle so badly?

Well, I'm not sure why there's so much water coming in, must be a high water table in the area. I've toyed with the thought of just putting in a pond pump with a flow rate approximately the same as the water coming in to just run all the time (connected to some form of a float switch to prevent it from ever running dry?)...my local plumbing supply house has recommended the Pro Series PS-C33 sump/backup unit as a main pump though, and as someone mentioned getting the wifi module to at least be notified when the secondary pump kicks in. They said that pump will allow me to place the float higher in the crock and set it to run an extra 5 seconds to clear the water lower in the crock. While not a 'cheap' option, it's not ungodly expensive either...anyone use one of them ever? It has a main pump, a battery backup, and a control device...

I should mention that yes, I do have a whole house 16kw generator for power outages...
