Kamoer NKP low flow peristaltic pump 12V dc DIY liquid small dosing pump for aquarium lab analytical 3mm ID x 5mm OD

I live in the deep South where it's hot and humid. We use the A/C for 10 months of the year. If I forget to put vinegar down the condensate drain every month, it clogs. After dealing with clogs a couple times this year, I decided to use this peristaltic pump to deliver white vinegar into the condensate drain every week. I have it wired to a zigbee relay, and then entire system is controlled by a Hubitat hub. One end of the tubing from the pump sites in the condensate drain, and the other end is in gallon jug of white vinegar. Every Saturday morning, a Hubitat rule turns on the relay for 30 seconds and then shut it off. This delivers about 50 mL of vinegar down the condensate drain. So far, it has stayed clear with no clogs.

Works as described

I used this pump to remove water from an under-floor burst pipe. I ran it 24/7 from 12V batteries and it never let me down. It did get quite warm at times, but kept on running. Pretty quiet as well.

Muy práctica, la utilicé para un proyecto de posgrado y funcionó a la perfección
