Return to install two liberty pumps and a float switch on a duplex grinder system. We dig up basin lid and lifted and shifted it to be level. Removed two pumps and the float switch, required to junction box near system. Installed new check valve outside of basin to replace failed check valve. This item was done as a courtesy at no additional cost. While on site, we reconfirmed history of system and components with Tim. He did mention a concern with the electrical. Stating that the plug in was required to be a gfci grounded switch, but there were concerns with daisy chaining grounds in such a way. Tim eventually elected to return the outlet to a normal outlet and has stated he hasn’t had any issues since then. There is also a concern that the alarm box may have been damaged or otherwise gone through stress with recent pump and alarm issues. I have tested 5e pumps and everything appears to be working as intended at this time. I was unable to replicate anything that may cause concern.
