RV toilet sprayer alternatives.

Courtesy Camping World
RV toilets, by their design, at times don't flush quite as cleanly as we might hope. To that end, manufacturers often provide a spray nozzle feature to assist in cleaning the bowl. It's a Star Trek solution, not because of being high-tech in nature, but it does allow you to deal with Klingons. But what if your biffy doesn't come equipped with the spray nozzle, are you stuck with stickies? Not at all, you can often add your own spray nozzle.

Some toilet models allow the addition of an after-market spray nozzle kit. Do you flush a Dometic? There's an after-market kit for that. It includes a spray nozzle, a clip to hang the nozzle on, and installation kit that includes a vacuum breaker. The purpose of the latter device is to prevent any liquids from the spray nozzle assembly from making their way backwards an back into the RV water supply system. Camping World will sell you one for a little over $60, but by being smart and shopping around, you can beat this price.

Keep in mind, in addition to the issue of these critters being a bit on the pricey side, some RVers have complained that because the thing is plumbed through the toilet supply line, there can be a bit of a loss off pressure, making your cleaning efforts a bit more difficult.

There are alternative approaches to this matter. Some RVers report (and we personally have experienced) that their shower head will reach out from the shower stall and down to the throne with ease. They just use the shower head to blast away at any undesirable bowl dwellers. OK, this is a really cheap solution, but unless you can hang onto the shower head while holding it over the bowl, then stretch and reach the shower control valves to turn on the pressure, you're apt to get a few drips on the floor. You pays your money . . .

Other alternatives? Sure enough. Put a plumbing T in the water line that serves your toilet. Incoming water flows into the T, then one side out to the toilet, and the other to a hose line leading to: 1) A shower head (with appropriate shut off valve) 2) A toilet bowl rinse head, or 3) a garden spray nozzle. The latter seemed like overkill to us, but hey, it does develop quite a stream.

But what about a vacuum breaker? If you're clumsy and apt to drop your new toilet bowl blaster in the pot and leave it there, yeah, you might want to add the vacuum breaker. Otherwise, it would seem pretty unlikely that icky stuff could make its way back into your fresh water system.


  1. Instead of the shower nozzle or garden hose fixture, why not a sink sprayer replacement hose? That's what I used when I did mmine 4 years ago.

  2. I have been installing toilet sprayers in our RV bathroom for 15 years. Imagine my surprise to go buy a new one and find it was standard. But the article was right on about connecting directly to a T off the supply line, not to where the toilet valve must be operated or you get little pressure. Now sink sprayers will usually hold full water pressure, but they are not made to do that. So best use a shut-off where it ties in for emergency cut-off --- or use the yard sprayers because they ARE made for full pressure.
