Customer called us out for a toilet making rattling noises. I inspected the toilet and found that the fill valve was the cause of the noises. I recommended replacing the fill valve or the toilet due to being 22 years old. Customer choose to replace the fill valve today. Customers water heater was 8 years old and the pressure to the house was 57 psi. I removed the supply line and the fill valve and installed new of both. Cleaned up and tested the new equipment throughly. The customer was very happy.
