Upon arrival I spoke with the homeowner and she explained to me that they needed a septic tank pumped because the tenants flushed an excessive amount of greaseInto the tank, after further evaluation I then gave her an upfront option and price on pumping up to 1000 gallons plus pumping an additional 400 gallons being that the tank is a 1500 gallon, after approvalI then began to pump the septic tank, after pumping the tank I made sure that I had gotten the grease out of the tank, after completion of the job I cleaned up all tools and materials and the homeowner asked if I would make sure everything was flowing in the house after knocking on the door several times I could not get the tenants to answer the door, at this time I am not sure if everything is flowing. - pump up to 1000 gallons - pump and additional 500 gallons.
