I have a jetted tub with 4 jets, 2 on each side. One of the jets doesn't function properly anymore. When the air intake is closed, it actually gently sucks water in and when the intake is fully opened it barely circulates water when the other are very strong. There is access to the pump and the rear end of the tub from the ajoining room but the effected jet is the at the front and against a wall. Any suggestions?
