Perhaps I'm missing something here; however, I'm not a plumber but we replaced our kitchen faucet with a bar faucet we bought at Lowe's. Don't even know the brand name, but the holes matched up and it went in without a problem. Maybe we were just too dumb to know to worry about it. Been in for about 3 years without a problem. Could not change out the bathroom sink one without taking the whole sink and cabinet out, so just cleaned that one up and left it. Now when you get to changing out the toilet, let me know how that works for you. We replaced the one in our 76 Sovereign
last week end but haven't turned on the water yet. I can't for the life of me see how this High Profile Thetford will not leak. Guess I'll know when Spring hits Oklahoma and I turn on the water.
