I recently replaced an old pump with a variable pump. But I am now wondering if I should have increased the length of the output tubing. I basically kept the previous dimensions. The variable pump manual, called for 12" minimal from the inlet side, nothing else was mentioned as far as the output. Just wondering if it's too short and could cause the multi port gasket to fail. Input would be much appreciated.
10" of out pipe to the multi port after the 90" elbow
