Customer called us out for a slow draining garbage disposal. On arrival I inspected the sink and found that only the garbage disposal side was clogged. I recommended clearing the trap from disposal. Customer agreed. I removed the piping under the sink and cleaned everything throughly including what I could see in the garbage disposal. Then I put everything back together and tested both sides of the sink. Everything was working properly and there were no leaks. Customers water heater did not have support on the expansion tank. Water pressure looked good. Under the sink the ptrap was set very low to accommodate high piping. Garbage disposal was 8 years old. I recommended getting these all fixed but customer was not ready for that today.
