Pump hammering after installing accumulator
I have a class B with a nearly new pump (Shurflo 4008, installed about 1 year ago). Even with the bypass, running the sink caused pump cycling to a degree though not as bad as it was with the old 3 ch...

That type bypass pump doesn't need any bladder tank, let alone a bigger one.
Having said that, mine works great w/ the little bladder tank,.....once I adjuster the bypass correctly.
And having said that, the 4008 is a cheap universal pump that works well for most I guess.
But I have had too many problems w/ mine, like the screws coming loose, until I installed lock buts on 3 of the 4 bolts. Then I had trouble w/ overheating and shutting down when ever using very low water flow. I finally removed the internal thermosistor, and no more problems.
But if I needed a pump, it sure would be a higher quality than the 4008.
