I'm glad others are upgrading like me
Finally finished - much nicer seat room. Problems
1) Have someone ready to turn off the water pump when you hear sssshhhhhhhssshhhh (that's the sound of water spraying everywhere
2)If the above happens, push down the pedal halfway - that will allow the water to fill the bowl, but not dump out everywhere.
3) It's ALOT easier to hook up the H20 line before you bolt the toilet down.
4) I learned too much about different thread sizes/types. It should have been an easy hookup, but the PO had replaced the water inlet with a 3/8" taperhead supplyline. The toilet has a 1/2" thread "pipe" threading. After trying various adapters, I got smart and removed the line to the shutoff valve under the cabinet. I had another 1/2" "pipe" thread fitting here as well (both males). After trying for a couple of days to get the right braided hose in the toilet department, I found success, a 1/2" pipe to 1/2" pipe 30" long braided hose in the dishwasher, washingmachine section. NOW it was an easy 2 minute hand tighten job - TADAA!
5) As mentioned before, the seat does NOT open to 90 degrees, only about 85-88 degrees without the "hidden shelf" cover in place. I'm just going to cut out the shelf and fill in the holes. It wouldn't bother me with the shelf, but just in case the inlaws come.......
