Water pump replaced with less than 3 running hours on motor. Will not come out of telltale in water or muffs. Used wire to clear line from tell tale no issues. Backflushed through telltale and got water out on muffs for about 45 seconds. Not sure what else to check on this thing unless the water pump is bad again? Any help or things to try?

I’d say to make sure the impeller is in the key slot properly and maybe check the poppet valve. Best I can offer until a pro comes along.

Hook water hose up to flush out hoses and see if any water come out pee hole, pop it valve may have t6rash also

Thanks, taking it to a shop to just go through it and replace anything that it needs at this point.
