I am trying to do a Bean Animal Overflow on my 225 but it is incredibly loud. I did the type in the picture below but I never got the water level to be higher than the top of the primary drain and did not draw in enough water. I then replaced the strainer on the primary with two street elbows making a downward U that was completely submerged as I saw in a YouTube video. It drew in a lot more water but it was still very noisy. I followed the instructions to the letter (except for adding the gate valve) but can't get it to be quiet. Any suggestions would be appreciated - thx.
