Hi All, I had my in ground spa re-plastered last summer and just noticed that the channel drain install took my tub from two pump suction locations to one. The current suction point has two pipes one for the filtration/heating/skimmer line (1/2 HP) and one for the spa jet line (1 HP). I have noticed that when I have the spa jets and circulation pump going the suction force at the back of the channel drain is pretty strong. I am not sure if this is safe and if the channel drain was installed properly? The pictures are of the tub in its original configuration (two separated drains) and after the channel drain install. Any feedback is greatly appreciated!
