Fresh water has been a problem for us so far. The built-in fiberglass tank was badly affected by venting blisters, and as of last summer, we weren’t content to drink water from it any more. We tried using Sanitred to fix it, which was a complete disaster!! Never ever use Sanitred products on your boat!!!
It was a major project to add a holding tank – it took about 4 months and touched so many areas of the boat. But it’s finally done, and I’m happy with the outcome.
While working on replumbing the head, the inlet hose spigot snapped off inside the Lavac Zenith toilet. Yikes! It left a piece inside, so we were left with trying to figure out how to get that piece out, and what to do about replacing it. The Lavac toilet is just too nice to abandon over a little failure like this. I’m posting this here in case anyone else encounters this problem with their 35 year old plastic part snapping.
