Thank you. I agree we could have went with a smaller pump. The inlet and outlet pipe is 2" and the pump inlet and out is 3". I never caught this until we started the installation of the pumps. I contacted the supplier and they said we would be okay but don't go smaller than 2". I assumed this...
It is a full port swing check valve. I have about 5 psi constant and I go up to 60 to 65. Not sure at what psi the noise goes away. Everyone I have talked to said the distance does not matter. The supplier suggest larger strainer. I took the baskets out and still got the noise. Only thing that...
Again thank you for your help.

The old system pumps were 1" line and we up sized to 2". We did take out an elevated 250gal tank on the downstream side. It was...
Thank you for your response
Start up only
Manually start and stop the pumps
After about 20 sec the noise goes away
90 elbow about 8" away
I will try and upload a sketch
60 to 65 psi
The relief valve is on the pump internal...
Thank you for your reply. I that was checked and the valves are installed properly. I have redundant pumps so I have two check valves. My first thought was to move the check valve to upstream of where the discharge side of the piping meet. This would eliminate one check valve and create more...
