    Could the Valletta T58, sticking out from the original mount cause a problem?

    So if I am thinking about this correctly, I have a 315 rlts tag along w/3 gray tanks, if I put the Valterra gate valve on all 3 of these tanks would equalize?

    Yes 2 Grey tanks with separate Grey valves. Black valve for black tank and a white valve to dump your fresh water tank.

    Reading some of the above posts some may have 3 grey tanks.

    Just to state the obvious... on my 28BH there are two grey tanks, but one discharges up front with the black tank and one has a separate discharge behind the axles. I'm guessing quite a few trailers have this sort of configuration. If you've got a similar configuration, you're out of luck regarding the use of an additional valve on the discharge line to equalize the grey tanks.

    See this thread with answers for 303/337 and some other units as well. Unless the factory connected differently in error yours s/b the same as noted in this thread. Starting with empty tanks and testing by running several gallons of water is always a good idea as many of us have done and shared over the years.
