The condensate pump for my HVAC systems gave out a couple of months ago. I went down to the basement and stepped in a puddle. It’s amazing how much water came from the HVAC system in just a day. I’ve never really liked this particular pump. It’s noisy and it has failed before – I’ve taken it apart to figure out what was wrong only to have it work again. It has a lever on the side where you can push down to manually activate the pump – to override the float sensor and I’ve needed to do that before. So as I sloshed through the puddle to the pump this time, I was surprised to find that the manual lever did nothing and that the power to the outlet was still on. I didn’t need much convincing to buy a new one. I got a new DiversiTech LCV-120 which has no mechanical float and is incredibly quiet. I really should have replaced the Little Giant with the DiversiTech at the first sign of problems years ago.
However, I don’t want to be without a condensate pump even for a little while so having a backup would be useful. And I’m considering making some sort of system where the DiversiTech is somewhat raised up and I have a second pump below it with some sort of battery back up to make sure there is never a problem again. And therefore, I set out to repair this thing – the pump that I hate, the Little Giant VCMX-20UL.[ continue reading »» ]
