Hi,
A few weeks ago we had (shall I say, a couple of large people in the tub with us uhhum). Needless to say, the tub overflowed with water over the side of the tub. Since that time, we have a couple of jets, on the same seat, that the water flows thu but not air. We have replace the seals on these jets and still no air. I have noticed something..may be normal...but I will explain anyways. The venturi knob make a gurgling noise after I shut it off....like there is water in there. This only happens on the knob controlling the side in question. Could it be a seal or something around that knob that the water may have leaked into? With the other knob you don't hear that gurgling noise. We have a Dreammaker X400.
