Clogs by room

Clogged RV sink or shower

In a trailer, space is the first problem. A small plunger that fits in a drawer handles the galley sink, the bathroom sink and the shower pan.

Where is the clog in the RV?

Galley or bathroom sink

Space is tight in a trailer, and the Mighty Tiny is 7.25 inches tall. Cover any overflow hole and keep water over the drain before you plunge.

Shower pan drains slowly

Lift the strainer and pull out any hair. Plunge with an inch of water in the pan.

Step by step

  1. Check the gray tank

    Make sure the gray tank isn't full and its valve is set the way you want. A full tank looks just like a clog.

  2. Seal and fill

    Cover any overflow hole and run an inch of water over the drain.

  3. Plunge with short strokes

    Seat the plunger and work short, firm strokes. RV drain fittings are plastic, so there's no need to force it.

  4. Run water

    Run the tap for a minute and watch the drain and the tank level.

When not to plunge

  • The RV toilet: it drops through a flap into the black tank, so follow the toilet maker's directions
  • Every drain is slow at once: the gray tank may be full
  • You've added drain chemicals
