280RK Solitude - Sink Drain

[treelog]

A newbie question, I have a 2023 solitude 280 rk, underneath the sink in the bathroom there is a small plastic box with a pump in it, I’m assuming it pumps out gray water down to tank on main level, why could they have not run a gravity feed hose down to the holding tank? Just curious

Because your bathroom sink is in a slide, and a gravity drain hose may not always work if it gets kinked by the slide.

Does it need any periodical cleaning or maintenance. I’ve had my trailer out only a few times for both times a few weeks at a time and notice the inside plastic screen is a little gunked up.
