My family has a 2001 SAN and since near the end of last summer the ballast will not empty through the pumps. It is a fairly minor inconvinience, as they empty when put on the trailer, but this means we can only empty them when we are done for the day. We are planning a trip to Shasta this summer, and I really don't want to have to drive it around with the tanks always full since it costs a first born child to fill the tank (and I am the first born child in this case). I figure since the pumps don't really fill the tanks either that it is just the pumps are finally shot. My real questions are then 1) What can I do to see whether it is the pumps, 2) How hard is it, and how much does it cost to replace the pumps if needed, and 3) What else could it be?
On a related note, the gauge that tells how full the tanks are have been on the blink as well, what can I do to try and fix those?
Thanks a lot to anyone who can help.
