That pressure advice was BS. High water pressure is not required to refill a toilet, and pressure is not used to do the flushing unless you have a pressure assisted model, but you do not. Mansfield is a pile of junk. Go to HD, order the Entrada. Toto is a highly respected brand no matter which model you get. Terry does not ship toilets due to the frequency of breakage. HD would have to deal with the breakage, so it would not be your problem. You didn't suggest ordering on line, but if you are considering that, here's a couple of things to understand. Yes, there are some companies that offer Toto (and other brands) at good prices on line. However, toilets are not packaged for individual shipping. Therefore, there are many that are broken during shipping. Now, if you inspect the shipping before signing for it, the shipper will have to replace it. Your cost will be nothing, but until all of the back and forth of paper work is completed, you will not have a toilet. Of course, if you accept the shipment without inspecting, it's you tough luck. My best advice is to live within driving distance from Terry and pick up at his home like I do. Well except for the time he was coming within 30 miles of my home and I could just meet him there.
