I have a hammering effect as my O/M-4 runs throu its cycle.
I run it with a Sequence Baracuda . O/M input is 2" outputs 1 1/2" I run the drum 1&3 , 2&4 Do you have any ideas as how this problem can be resolved?
Thanks in advance

What do you have on the end of the outlets in the tank? plumbing pics always help.

It's a very common problem. Give Paul a call. I have the same issue running a hammer head pump. Paul has made a custom drum for me that works 100%
what he does is bevel out the drum so that water follows out of all ports all the time but not much

I had the same thing happening to me once and found that it was caused by some sand that got down into the drum. Took out the drum, rinsed it clean and flushed the body, put the drum back in and that was that. Just my experience but might not be your issue.

Good Point Grizz I guess I junped a few troubleshooting steps

thanks guys,
Jason I was thinking that it might have had something to do with the ports opening and closing. Before I give Paul a call I will just open and clean out the drum (the system has no sand but I guess it could be some pvc cuttings that have gone throu the system during the fresh water test.
