Do one partial rebuild on master toilet replace hallway upstairs toilet and replace the flush gasket in the first floor toilet. Replaced the red flush gasket with a yellow gasket. Started to work on the guest hallway bathroom and just do a partial but when I started to take apart the supply line and remove the fill valve I noticed a leak so the customer went and got a Kohler highline and I installed that in the guest bathroom. The supply valve and supply line were also leaking after installation so those were replaced aswell. In the master bathroom I changed out just the fill valve and flapper for a partial rebuild
