Grey water tank removal
I had a fifth wheel myself for some time and the cost of having someone replace my black water tank was ridiculous. Upwards of $2,000. Then I discovered why. Later model Alfas often had electric dump valves for each tank. Add in the fact that they’re out of business and there’s a major headache waiting for you.
Wish I could answer your question. Decided just to sell my trailer (had inherited it anyway) and let someone else deal with the issue.
On this forum, I don’t know that you’re going to get a lot of help beyond, “Make sure you wash out the tank first with a lot of clean water.” I like to use this site when I’ve got some questions about my new fifth wheel – I’ve got a Forest River Sandpiper now and I love it.
Best of luck to you.
