Low hot water flow


I have a oil fired weil mclain boiler with a coil attached it is a Ford Products aqua booster. A week ago I started getting low hot water flow to my taps. Cold flow is fine in all taps. I took off the taco 006 circulator pump coming from the water tank,opened it up and all the impellers were gone of the pump shaft. I bought a new one put it on and same problem. Are the impellers stuck somewhere in the coil? Would they disintegrate? When you first turn on the hot the flow is good then drops down in front of your eyes to a pencil or trickle depending on the distance you are away from the tank. I also took the pressure valve off the top of the storage tank to look for blockage but that was fine. When I draw off the tank does it get replaced immediately causing the low flow to begin? Im thinking the coil is blocked by the impellers or hard water. Any thoughts are great. Thanks

Re: Low hot water flow


I think that you have diagnosed the flow problem.

The remnants of your impellers have wedged near the first turn in the system, and are causing a partial blockage, and when the flow picks up a broken piece lifts up and almost blocks it completely.

You possibly had one crack in an impeller, which broke, then this part took out the rest of them and all broken parts lodged at the next bend.

Take it loose, and backflow it to flush the parts out.

Any chance it's the expansion tank?

So I fixed it, I flushed the cook using a utility pump and white vinegar. Sediment built up in the coil. Problem solved.

Re: Low hot water flow


Hard water build-up and sediment was my next guesstimate.

Glad that it was an inexpensive , fairly easy fix.

Just remember to do this every once in a while, may save your impellers.
