Lake Jon

I’ve had a Dr Wellness hot tub for several months and it’s been great, except for two things -one not the fault of the tub. First, one of my son’s friends stepped on the cover and it cracked and I need a new cover or perhaps they make the foam inserts?? Second and most annoying are the waterfalls! I HATE THE WATERFALLS!! All they do is spray you in the face every time you stand or sit. I popped off the covers and tried to twist them to shut them off and no luck. I’d fill the mf’ers with cement if I could. The water pressure is very high and I’m not sure what would work to stuff in there. Thanks.
