Called out today to preform annual tankless flush and while on site customer.asked about a sewer ejector pump in the basement making noise and a garbage disposal leaking Looked at the disposal and found that it had loosed it self up and was dripping all I had to do was tighten back up by hand Looked at the sewer ejector pump in the basement and found that when it kicked on and would make a knocking noise that continued after the pump has kicked on recommend that we replace the pump and the check valve on the system and the lid for the tank due to if we open it we will brake the lid and replacement is the Best option if we have to pull the pump out of the pit Flushed out tankless heater for customer and ran flush for 1 hr to insure heater we flushed properly Customer states the unit is making a noise and could not rennet if it through the area code for it needing to be flushed or if it was a combustion issue flushing heater now I would recommend replacing blower motor inside b
