leaking water pump

[brokenaxle]

Has anyone had issues with the shurflo Revolution water pumps. After just over a year owning my cedar creek silverback the housing on my water pump sprung a pin hole leak in it. There were no cracks in the housing nor was there any other damage you couldn't even see the hole that was leaking and it was no more than a steady slow drip. After disassembling the pump and inspecting it for cracks or other damage it looks like the housing is very thin where the pin hole was. I have winterized many trailers and the only time this pump was used was to pump anti-freeze into the system to winterize it last fall. Otherwise the trailer is hooked up to city water. Also a lot of camp grounds have excessive pressure but the part of the camp ground we get our water from has very low pressure.
