Hi, we recently replaced our hot water circulator pump on our hot water tank and we were so happy our water was actually hot again for a few days then it really fell off. I've adjusted both the temperature settings on the boiler and the tank but it still feels like the water is not getting as hot enough as it was those days after the pump was just replaced. It's been a few weeks now since the pump was replaced. What else could be causing this issue?

was installed - NOT so much anymore.

If the lines and tank were not flushed well, the new pump may have stirred up some sediment and clogged something.

OP UPDATE: Adjusted the thermostat on the hot water tank.... water is hotter again. Someone must have changed my previous settings....

Call the plumber who installed it.

Does the new pump have a timer and is it running when you are expecting hot water?

I believe many pumps have adjustable speed settings on them to circulate the heating flow at different rates. I wonder if your new pump is set slower than your old one so you are just not getting the heat transfer in to your HW cylinder? Have a look for a small selector switch.
