Below is my install of rotary tank sprayers in my T310SR. As you see this TT bottom it is the enclosed tanks option Sunline provided. The layout is different then the exposed tanks setup and as such some things my not apply to your tanks. But you can adapt as needed. I will do most of this with pics as it says more then I can in words.
I used the Camco Rotary spray nozzle
. On my prior T2499 I ordered from Sunline the parts they would of used if it was installed at the factory. The Sunline sprayer is stationary and looks like this.
The Sunline sprayer is similar to the Quicke Flush by Camco but is a different brand. It is a straight nozzle that squirts straight ahead and on some angles. It worked good however I wish I had 2 of them in the tank to speed things along and get better coverage.
This time I wanted to try the rotary nozzle. With my tank layout, I used 2 in the black tank and 1 in the gray tank. The black tank is a shorter height tank and more square. So is the gray tank. Pending tank size and where you can place these sprayers varies. Sometimes it is more of how you can get in to even drill it in there…
A heads up if you are getting the rotary nozzle. Test it out on the lawn before installing. I ended up with one that would not rotate right out of the box. For those interested on what the spray pattern looks like, here it is.
The test setup
A partial turn on of the hose
Now full on. The picture does not show it but water is flying every where including on me…
And now one that does not spin. Water does come out, but no rotation.
Next is to figure out your tank location and how you can mount the sprayer. Sometimes there is a frame member in place of the “perfect” place so you use the next best place or be creative in drilling. Ideally on the black tank the sprayer points towards the outlet side/end to spray towards the drain. This is what Sunline told me as well on my T2499. If you can hit the tank sensors with the spray that is icing on the cake.
Before drilling in the tanks I did a test drill on a piece of ¼ plywood to make sure the hole size was right. 1 ¾ dia. Much smaller and it will not go inside and much bigger you cut into the screws. This is the size Camco states to use.
Here is my black tank.
Here is the gray tank. Here I could not get the sprayer on the opposite side of the outlet. However the gray tank flushing needs are different and you need more of a wetting rinse to get the soap scum out. Here I blast against the back wall and it runs out.
Camco gives you a drill template that you can tape on and drill pilot holes for. Here I had to get creative to work thru this cross member. An extended shank drill bit.
And now a hole saw with an extension. You have to assembly it in pieces.
And the end results of drilling/sawing
You want to pre tap the holes in the tank with the screws. I recommend you do this so you know for sure all 4 holes line up. If you pass over this step you will be doing it with a ton of silicone on the sprayer and make a mess if one hole does not line up.
Now for the silicone. I apply to the sprayer and the angled adapter if you need it. I do not put it on the tank as if any hangs over the hole, you will get it on the spray head. Ask me how I know this….
I did the 1st one that way and the other 2 this way.
When you tighten it up, it will ooze out. The silicone lubes up the holes so do not over tighten the screws or it will strip out. I could tell the 2nd time they went in real easy then the test fit to tap the hole.
Then smooth it out if you like. Bring paper towels under with you. Ask me how I know why……
Now to the pipes. Camco can provide a simple hose and fitting that does would well in most applications. However in my case I went further. I have PEX tubing crimp tools and once installed right there is no leaks and no loosening over time. I did not want to chance a leak in the enclosed tank section so I went with the PEX fittings/tubing.
The 2 black tank sprayers
The gray tank sprayer
I took all 3 to a manifold with valving. I can select which tank and which sprayer. Some CG's have good water pressure, others do not. Since I have 3 sprayers this give me all the options.
Here is how I hook up and use this in conjunction with my RV hydroflush. I had a similar set up on my older camper with 2 sprayers.
The hose has quick disconnects so it is snap on and off.
And then I install a plug in the water feed to keep road dirt out of the fittings.
I used the hand wand thru the bath room window now for almost the last year on this new camper. It works well but is a task to deal with and I only get the black tank. I also had one garden hose shut off blow apart in the bath room…. :
. Cindy could not run out and shut the thing off fast enough…
. Oh what a mess….
Never ever use a plastic hose shut off inside. Use brass….
Having the tank sprayer on the T2499 and now not having them, is like not having a power jack and then going back to the crank. You get spoiled quick. These sprayers are a luxary that once you have them, you will never go back. And when the DW keeps saying, When are you going to get those sprayers things installed! …
. So tank sprayers are DW approved!
Hope this helps spark some ideas for others and happy flushing.
