Red Lion RL-SPS33 1/4 HP Sump Pump Water Removal System with Vertical Float Switch and Five Gallon Basin

Used this to replace our old pump in the basement. Works great. Would recommend.

Great pump. Working solid for a year. No issues.

I purchased this pump to replace a dead older laundry pump. This thing is super solid and easy to install if you have minimal plumbing skills, very recommended.

An error in the installation manual drawings indicates that the ports on the top of the lid can be used interchangeably for waste or vent. This is false. One of the ports is smaller on the interior side of the lid to fit close with the outlet pipe from the pump. If the other port is used for waste, much of the pumped water will circulate around the larger opening back into the basin and not develop enough pressure to discharge. I falsely assumed that the manual was correct and installed the waste on the wrong port, requiring disassembly to reorient the pump and do more PVC work to cross the vent and waste. Make sure the vent port is connected to your actual DWV venting system. Trying to shortcut with AAV or island vents will pressure lock the system and cause malfunction.

Overall very impressed with this pump! I just got it today and everything lined up to the old liberty 403 pump I had prior to this making the hook up very simple. Pump is nice and quiet compared to my old one. I’m hoping it will last as long!
