Pump failure looks to be a concern with my setup, and others.
I have a backup automatic generator and backup propane heat.
If the boiler pump fails and I’m not around,, the whole operation is in jeopardy.
I can get another cartridge for the pump.
Don’t like the idea of changing it outside at the boiler at -40.
We know it will be close to -40 when it fails.
If I’m home when the pump fails, I would have a very short window to change it out, before the lines at the back of the boiler freeze.
If I’m not home …….forget about it.
I’m installing valves inside the basement to drain the lines before I would attempt to replace the pump cartridge.
I’m kind of a belt and suspenders kinda guy and was thinking about adding another pump, in series, inside the house.
Would this be feasible?
Could I leave it turned off till needed
Would water flow through it easily?
Could I use a smaller, cheaper pump, as backup?/
Is there anyway to hook it up to come on automatically, if the main pump at the back of the boiler fails?
