Tahoe Faulty Water pump?

[YenkoZL1]

Hey guys just curious if anyone has experienced faulty replacement water pumps on 96-99 tahoes, yukons, etc...? I ask b/c I have gone through 2 water pumps in roughly 3 years. 1st one was a GMB (N.America) High flow pump which gave out with roughly 30k miles on it. Leaked from the weep hole and front bearing.... So this time around I bought an OEM AC Delco, brand new. And now with roughly 4k miles on it, it's leaking from the back plate. The plate on the back which is sealed with a gasket and screwed in place. I have never had an issue like this before on something so new. Anyone else experience this?

I know the pump is good so I'm gonna get a gasket kit and see what happens. The leak is so slow it turns to jelly before it gets achance to drip.
I have electric fans on the truck that kick on at 195 degrees when the thermostat opens so I dont think its a pressure issue(not yet anyway). And the thermostat is a fail safe one too...

All thoughts welcome.

perhaps too much belt pressure?

That seems like there might be something else going on. My original water pump crapped out over last summer and I had to replace it with an AC Delco one. My Tahoe had around 97k on the clock when the original one crapped out. I did not do the repair myself, and if memory serves me correctly, I believe I spent $225 to have the new one put in after I purchased the part.
