I have a sump pump that is electric. It has I believe a 2.5" exhaust?
pipe. Pump is in basement floor and water rises probably 10-15ft and
moves horizontally about 6 ft. I burned out a few pumps, so I got a
bigger BADDER one. After reading I think this is the cause of my new
watter hammer problems. Pump is putting stress on my piping and has
caused one strap to snap. With the snapped strap, the whole pipe is
slamming when the pump turns off. Its loud, housewide. The check valve
is about 1 ft over the top of the pit.

I have looked for water hammer devices for 2.5" PVC pipe but I have not
seen any. At this point I am considering adding my own length of pipe
in a T fashion across the horizontal portion to absorb the hammering
that occurs when the pump shuts off.

Is this a good idea? Any other ideas/considerations?


Note: the broken strap is behind some drywall and I don't want to open
it up, though I might do that.
