My pool was just completed-yeah-however I am noticing that the air intake jets that go to the jets on my bench are very loud. The PVC pipe is about 1/2 inch that is right behind the coping. Should there be some sort of cap with a hole or something to help muffle the noise? Any help would be appreciated. I am hoping I didn't make a mistake in having them installed. I thought they would be very therapeutic but the noise is disturbing.
