I had an issue like this that took me awhile to tract down. So not to bore you, it ended up being a fitting on my water pump. My water pump was placed under the upper flooring in the bathroom vanity(my MH has a step up from kitchen to bath ) thus causing the water to travel down under the floor and then eventually end up soaking the compartments. I finally moved said water pump to make it easier to service and keep my eye on. Good Luck with yours.
