I have a 2019 31MB fifth wheel, on our most recent campout the black tank sprayer stopped spraying, it worked 2 weeks ago. When I hook up the water hose to the inlet and turn it on I can hear water entering the black tank and it flows out the discharge pipe but I cannot hear the sprayers working like I always have. Any ideas
