Has anyone added a gray tank to a White Water 155. I have purchased an external gray tank but would prefer to mod my 155 if possible.

I just retrofitted my 2014 155XL. I noticed the new ones have a gray water tank, so I checked with my dealer, and they ordered the tank. Now I live in an expensive area. Labor is high and it was a lot of replumbing, so it wasn’t cheap, but since I plan to keep my Retro, I had it done.

Parts are only about $350, and if you know what you are doing you could probably do it yourself. Thank needs a vent. You end up with two hose dumps, the greywater tank dump tucks under the body, unlike the blackwater scissor valve.

Now another issue I had was clearance overall, which stems from the original 155 being designed to fit in the average garage. The grey water tank resides in the area where the drop floor is in a 155. If you have a 155 with the drop floor, I don’t see where you would fit a grey water tank. The 155XL just added height and made the floor flat.

Anyone wanting to do a retrofit should also get a spring lift kit installed which raises the trailer 4″. This gives enough clearance for the new dump valve to reside underneath the trailer. Inconvenient to have two valves, but doable.
