How to tighten those impossible-to-reach under sink nuts

When traveling in a motorhome, camper or trailer along miles of poorly maintained highways, bouncing over speed bumps, down dirt roads, and to all those neat places we RVers tend to travel, the cumulative miles tends to loosen nuts, screws, and fastenings.

Most are simple to re-tighten with a couple of screwdrivers and a set of wrenches. But some of the nuts that loosen are hidden inside lockers and not readily visible, especially those up under the sinks where dripping water can and ruin items stored in the locker and eventually rot floors or cause wiring problems.

But have you ever tried to tighten one of these nuts? You have to be a contortionist to reach the space, then find no room to turn a wrench. That is why the "basin wrench" was invented.

This wrench can reach into those tight places, and with its swivel head, lock onto nuts that you turn from the handle well below the nut. It makes an impossible problem a simple task. Every RVer should have one of these in their tool box.
