I'm still working with Atlas Plumbing Co to resolve an issue with a toilet seat they installed. I ordered some stuff months ago through TOTO and paid a lot of money for it. When the toilet seat was installed it didn't operate properly. Either it wasn't put on securely or there is a defect in the toilet. Atlas isn't taking any responsibility for the problem so I've been following up with TOTO and keeping Atlas in the loop. TOTO is honoring the warranty and replaced the seat which Atlas is scheduled to install today. They just texted me they are on their way. After TOTO gets the original seat back, they will test it for defect and we'll know if it was a manufacturing defect or installation mistake. I am waiting for those results before issuing a judgment.
