My trailer came equipped with a black tank washer and I have used it numerous times. Last week when I tried to use it, it was stopped up and would not let any water flow into the tank. When I turned on the water spigot supplying the tank washer, there was no sound of water running. When I turned off the spigot, and disconnected the hose, the water in the hose was still under pressure. So I do not believe there is a leak.
I got a diagram of the washer from Jayco and other than simple piping going to the black tank washer, there is only an item identified as a vacuum breaker. It seems to me that the only places the water to the washer could be blocked is at the vacuum breaker or at the nozzle in the tank. Since the washer at the supply hose connection has a screen, I'm thinking that it is unlikely that the nozzle is stopped up. That just leaves the vacuum breaker as the source of the problem (if my analysis is right).
The most common vacuum breaker on a tank washer I see mentioned is made by B&B, a model 571. Here's a picture
Is the problem likely the vacuum breaker or a stopped up nozzle?
Is there an easy way to unstop such a nozzle (which is covered up by the Coroplast bottom)?
Is the B&B model 571 the vacuum breaker Jayco uses?
And any other thoughts...
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
