Install rinse flush nozzles to black and grey tanks.

Adding tank flush nozzles to simplify and more thoroughly rinse tanks. Normally when dumping, run water down toilet and down kitchen sink to help rinse tanks. On the black, if able, connecting a wand that goes down toilet to 'blast' walls of tank. The wand is effective to help clean tank but inconvenient and not always practical or have a source of water.

Utilizing the campers water pump, letting water flow does help, at least at valves and unless there is water available at dump station the only option. However currently replacing tank senders with SeeLevel system and having everything open realized its virtually ineffective. Specifically the grey tank. Both the drain inlets to tank and the dump valves are on the same end of both tanks. The grey tank is over 5' long, so flowing water pretty much goes into tank and out the valve. Black being more square not as bad, but still unless wand used most of tank doesn't see rinse water.

Since camper tanks are exposed decided to add Camco thru the tank non rotating nozzles. Will introduce water at top of tanks, some flow thru out and just convenient to hook up water source at same location as dump valves.

Units arrived-what junk.

Not bad hose but twisted in package. How do you recoil a hose and make it fold-only by twisting, it would not do it on its own. This apparently a constant issue with Camco packaging. Mine also was missing the hose washer on swivel connection. The brass fitting are VERY thin.

Installing on the grey tank was planned at opposite end from valve. However plumbing it would require elbows on the hose to get around tank. Briefly thought about installing the city hose connection on opposite side of camper, might help but the generator is very close and getting outside the plastic tank cover would be problematic. End of tank at valve side is exposed inside cabinet, plumbing would be easy, have access if issue and put city connection in more convenient location. Compromise at best, not as effective to rinse tank but I'm not burying the tank connection where I cant get to. Plus don't want to deal with plumbing, cutting up tank cover. So...

Installed on valve side of grey tank. Nozzle does have 3 jets that may reach opposite end of tank. But I am using more for adding water & flow than blasting. It will be more coverage than running water down sink. After seeing the fittings and the numerous reviews of folks having hoses simply blow off, I'll be keeping water pressure low. Still, better rinse ability than we had before.

I added extra screw holes and used stainless screws. For sealant I used DAP all-purpose adhesive sealant, 100% silicone, Aquarium safe/food grade. I assume any Silicone would seal, but it was the only product that didn't say -'not for underwater continuous use'. Also if you happened to drink the waste water, at least you know it wont be the silicone that makes you sick.

Installed the remote hose connector at out side wing. Hose is slightly higher than tank fitting.

Next day tested, fitting at tank dry, no leaks. Look out side and water is pouring out the 'factory' crimped fitting. Or I should say the factory un crimped fitting. Swivel fitting has an inner tube that slips inside hose, an outside tube that's supposed to be crimped to hold and seal hose to inner tube. Crimped but does NOT contact the hose. Hose is slipped over the inner tube but nothing holds it? Had I turned up hose full blast it would have simply blown off--Good grief.

My fix was cutting off the outer tube to used a band clamp. With a mini tube cutter, tightening in VERY small increments, going round and around, cut tube. Because the tube is sooo thin you cant force cutter-let the round and round action cut, actually score thru the tube. Outer tube once separated slid off.

Just enough room for small band clamp. Reconnected and tested-dry! What utter junk.

The real fix is replacing the hose with good hose and better fittings. Length and making/using old bracket will take some thought. I'm sure will happen sooner than later. I don't trust the vinyl hose and thin fittings at all-even a little. Hose is only about 14" long so will have to make . The black tank, I could coil up extra hose so can use short 3'-4' pre made hose if any issues.

For now grey is operational.

Black tank. Was going to do this later but since I have time and everything is open going to install second tank rinser on the black tank (now that I know how to fix). The black tank I'm installing nozzle on top. Only option. Also if issues less likely to leak on top, say if anti-backflow fails. Even then only 6" clearance so cant use power tools to cut/drill.

Oh Boy. Used 1/4" box ratchet to spin a 1" bore bit. Got down to where I could finish with xacto blade, screwed in a lag bolt to keep plug from falling in.
Same deal with the screw holes. Even my cordless that folds is too tall. Used 1/4" socket on ratchet with drill bit. I ended up starting holes with sharp truss head screw.

Prepped for rinse nozzle. Hose will exit at level of top of tank and go to remote hose connection on camper skirt above the grey connection. It will be several inches higher than the grey but both will be accessible.

Using stainless screws to attach nozzles to tank. So my telescopic magnet wont retrieve the last screw I dropped into tank--Oh I have a piece of super magnet from old hard drive, wonder if that's strong enough- the stainless is slightly magnetic...

Worked!-retrieved drop screw. I'll 'fix' the hose before installing.

And nozzle installed.

Routed up and over about an inch higher than tank. Wrap bend in Gorilla tape hopefully to stave off hose kinking.

Slipped a piece of old loom before running across box to hose connection. Secured with some EMT clamps.

Repeated process of cutting off outer band to use hose clamp at remote end. Second one leaked worse that the first one. Later I am going to replace hoses. Use pre made hose- cut out middle section to reuse formed ends, reassemble with barbed couplings. Allow running hose thru small holes, fit in rinser bracket-

Reinstalled the lower plastic tank cover that was off to install new monitor system. Caulked. Tested-so far no leaks.

Recoat the box-done.

Should simplify rinsing tanks, assuming water available, so might rise more often. At minimum picking hose end shut off ball valve so I can throttle at the connections and/or quickly turn off. Jeesh- really dont trust this. May put together a Y connector from source hose to rinsers. Allow just one connection at 'station', easy on/off for each rinser and throttling control at camper instead of back & forth to faucet.


Like this. Hose Y with shut offs to throttle. Two 4' sections of 1/2" hose, premade less than 4 M/F ends to make?. In the garden & hose section, RV water safe. Over in the RV section different brand same hose $12.99?. Anyway.

Now that this Octopus is made realized what I should do is remove the failure prone clear tubing and ends/ route the new hoses directly to rinse nozzles. Hard mount the Y on camper. Wouldn't have to store and only one hose connection to make. Fairly simple do change, but I'm done for now. I may do in future or definitely if any issues. I suspect as long as I pay attention and keep volume low should last.
