Sump continuously running and emptying outside yet the water level hasn't really gone down that much in 2 days

This sounds perfectly normal, though I might inquire about whether the output pipe is really taking it far enough away, in a direction free to drain away from the house. If it does not, you can end up ...

Two check valves in a series on discharge pipe

With the two in series you will be protected against one valve being stuck open. I don't think it's necessary and I wouldn't install two in series but since one is already there, no sense in having to ...

Sump pump automated battery backup

You don't want to do that. An inverter powerful enough to start a sump pump will also have high standby losses. It will burn your battery down in short order. When you're dealing with a 12V ...

Two check valves in a series on discharge pipe

The check valve is there to prevent backflow from the discharge pipe (which is usually vertical as it leaves the sump) from filling or partially filling the sump well back up. There are two main ...

Sump pump only turns on when I open the lid - working ok?

It's likely that the flexible output hose is interfering with the pump float. When you close the lid the hose flexes into an S shape, laying on top of the float. The best solution is to eliminate the ...

How can I power my sump pump in a power outage?

In most cases an extra sump pit is pure plumber profit - if the sump is not tiny, the backup pump can use the same sump, and just be set to come on at a higher water level. The practical problem with ...

Ice maker to sump pump has water run back into it, any ideas for a fix?

It appears to me that your problem is that the ice maker drain is BELOW the trap. So anytime there is water at that level, gravity will draw it into your ice maker drain. I think you'd be better off ...

Ok to connect a 1.5" sump pump outlet tube to 2" discharge line using a no-hub fitting?

That will work fine. What you want to avoid is reducing from say 2" to 1.5" as this can cause things to get stuck and block the flow. But you should be good to go with a 1.5" opening ...
