Does anyone know where the black tank sprayer is located and how to access it on a keystone hideout?

My black tank wash down sprayer seems to be clogged. After searching the forum for I have narrowed it down to the sprayer that is inside the tank. And many seem to fix this by removing it, cleaning it, and making the holes larger. But I cannot seem to locate the sprayer's location. I have a 2015 Keystone Hideout 26BHS with the cold weather package. I do not want to start tearing thinks apart without having an idea of where to look.

I have checked the back flow valve and it functions. The sprayer worked after a trip several weeks ago and now the hose just pressurizes and does not spray into the tan.

Thank you for all the help.

Well........
Nozzle will be installed in one of the black tank sidewalls so you WILL hae to open/remove the coroplast material on bottom of trailer under the black tank

Black tank location will be close (within reason) to where the dump header comes out and in line with the roof vent.

Other then that......it will be a guesstimate.

So drop one end of covering and have a PEAK inside underbelly

Have you tried hooking a shop vac up to hose fitting and see if you can suck anything out?

Anti-siphon backflow vacuum breaker device under sink is OPEN to atmosphere-tank side/closed hose inlet side unless water is flowing.....so shop vac would NOT suck anything

Forgot about that vacuum breaker device Old Biscuit. I guess an empty tank would let you get a small amount of suction but probably not the answer.

How about compressed at light pressure? Or fill the tank with clean water and add some Ridex and let it soak away buildup on the spray head.

Thank you for all the help. I have tried compressed air, it did not clear the blockage. I was wondering if I had to remove the liner on the bottom of the RV. The Tank is full/soaking for the 3rd time at the moment and I will try the air one more time, then move on to removing the sprayer.

Update
The sprayer was on the side of the black tank, directly behind the outdoor kitchens gas valve .

Thanks for the help

I found on my Keystone Sprinter that the hose was kinked just on the other side of the outside hose connection. I removed the screws and cut the silicone and pulled out the outside hose connection. I found they used a cheap hose that you would use under a sink or a washer hose just crammed in there. I would have replace the hose with a stainless hose, but I could not find where it connected to the PVC piping on the other end. I ended up cutting off the end were the kink was, replaced the end with a new connector, and put it back together. Works great now. When I take it in for its yearly service, I will have the dealer show me or just replace the hose with a non kink hose.
