I finally got some help to make the move from the 110 tall to a 150. Took a couple hours to complete, but totally worth it. I think they enjoy the extra 2 feet already.
dang... I had feared that would be the case...It is loud though, not from the 2" PVC, but from the reducing to 1.25" corrugated
Glass tops if they completely cover the surface can help a lot too.If the union doesn't work build a canopy. You can honestly build one for well under $50 with only a cordless drill and some paint/stain. Have lowe's cut the lumber, screw it together and paint it. You will be amazed at how much that will quiet the overflow.
