In this video, I will detail how I replaced my non-working black tank sprayer nozzle. Over the years, it can clog from hard water deposits and debris. I’ve pulled it out and cleaned it before but this time I thought I would swap it out for a brand new part. The OEM installed a flushing system called the No Fuss Flush.
I found a compatible sprayer nozzle from Thetford. Once the underbelly material is pulled back, the repair is very straightforward. The hardest part is getting the old silicone sealant off. I used a hive tool and plastic razor blades for the job. I removed the water line from a nearby Pex connection to make the job easier. Heating it with my heat gun on low helped to disconnect it.
