Estimate to replace float on sewer injection pump in basement Previous estimate was to replace sewer injector float switch. After pulling off the lid and noticing that there was a bunch of buildup of toilet paper and grime on the float switch I pulled the toilet paper and gram off of the float switch in the float switch float it up and it’s working perfectly fine. So we are not charging the $600 to replace the float switch. We are only charging the $322 to do the cleaning on the pump and float Switch.
