we got a bunch of work done at just cats in fort lauderdale (everything they touched broke, don’t do it) including getting the AC units salt water circuit flushed on the stbd side (it’s used more).
anyway either because or coincidentally the distribution. manifold on the pump side developed several pin holes. the service guy did not notice these (and did not tighten a clamp) even though they sprayed salt water up
into the room if you removed the access cover in the floor. Titan marine indicated that the manifolds are the wrong material and built us a plastic one. worth checking. see photos of hole in middle outlet and another on the spline fitting
