Do u have a closet near the bathroom???
also where is u'r fresh water fill??? (not the one for city water hookup the one that u fill u'r tank at home)
I bet more than likely u'r pump is under the closet or even if the fridge is ner the bathroom ,, it maybe under the fridge...
I have a Tiffin Alegro Bus 40ft ,, and my pump is in the very back under the small closet next to the bed ,, there is a panel under the carpet that has to be removed to access it ,,,
Post us back and let us know what u find
BTY welcome to the forum
Don't know if it helps...but in my GB it's located in he basement where you fill the water and get to the tanks, back right corner behind a fiberglass panel that you have to remove. It's a pain and you need long arms...on mine anyway.
If you have your numbers on your coach, GB should be able to send you a diagram. They did for me years ago berfore Coachmanbought them out, I would hope that they still would.
BTW, the 1st 2 times that it started to act up...I just took it apart and cleaned it up and it worked again fora couple of years
I ended up cutting mine a little. If it is behind the panel, you have to get either a strong hand and or wrench behind the valves to unscrew the fittings. I would think that they would have plumbed it in a better spot...but, when was the last time an engineer worked on something that they designed
If there is a way, I would re-plumb where it mounts for the 'next time'. Hind sight being 20/20...I should have
as long as the lines are blown out and the WH bypassed ,, also how much antifreeze did u use???
Make sure u get it thru out the coach and dump some in every drain u have ...
If u'r not in the sub zero climate then u should be ok
