Primary loop Bumblebee took a crap can I run my boiler till new pump arrives?

Drewgrizz Member Posts: 21
I used Bumblee's when I built my system 5 years ago and the primary unit is giving me the old E05 code so I am gonna replace it with a 007e. The boiler starting banging early this morning so I shut down the radiators. Heat was still working but I guess it was kettling in the heat exchanger causing the banging. Is it ok to run the system like this for a few days till the new pump shows up? Or will it damage the boiler? It's an older Lochinvar natty unit.

    Might damage the heat exchanger or worse.

    Ketteling? You mean boiling and making steam? Water hammer very bad. Water expands about 1600x when it flashes to steam. In a sealed system, that can be a serious problem.

    You might be able to redirect flow and use the secondary pump as the primary.

    Go get a regular 007 to stick in there.
    You near a lowes or HD? You have shut off flanges I hope?

    I ordered a 007e on Saturday from Amazon, will be here Tuesday. I have shutoffs on my manifolds, but the primary loop is gonna make a mess. Luckily it's been in the 60's here but is supposed to drop into the 30's for a high on Tuesday. Probably should be looking at a replacement for the other bumblebee after reading the comments about them. They are/were 5 years old.
