Review: Nice peristaltic pump to keep the A/C condensate drain clean - 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.
Review: Perfect For My Plant Watering System - I'm using 6 of these pumps (one per pot) in an ESP32 controller based plant watering system I designed and built. I've got a container I'm using as a water reservoir, and use flexible silicone tubing to deliver water, with a tee at each point where I've got a pump connected. I'm driving these pumps with only 5V instead of the 12V spec, and they work fine (at a lower flow rate, of course). I've calibrated the pumps to know their actual flow rates (they vary about +/-15 percent from average). Although there is unit-to-unit variation, they are very repeatable over time once calibrated. I've got soil moisture sensors in each pot, so with the appropriate number of days between waterings, and when the soil reaches the appropriate level of dryness, I command these pumps to deliver a specific amount of water (different for each plant). I've been using them for several months now, and all are still working perfectly.

## Questions & Answers

**Q: How do you control the flow rate?**
A: for me personally I have it set up on a relay and I am using a timer to control my flow rate

**Q: What is the volume dispensed per one revolution of the motor?**
A: The motor shaft rolls against the 3 rollers which are rotated much slower. Theoretically the circumference of the motor shaft and the inner diameter of the tubing could be used to calculate the volume (drops) per rotation as the rollers travel 1 motor shaft circumference along the tube per RPM.
 I'm hoping to find a brushless motor or motor gearbox combo that is about the same RPM. I don't like brushed motors.

**Q: Is this rated for continuous duty? Reviews say no?**
A: Not suitable for continuous duty, it is recommended to use it for less than 15 minutes at a time

**Q: Which power supply do I buy to power this unit? I know it's 12v duh!**
A: I use it on my boat hooked to the 12v battery system.  If I were using it at home, I would use a 110v to 12v "brick" from some old gizmo.  I keep all my old chargers and I'll bet I've got 6 12v bricks in my old brick box: just cut off the adapter and wire it to the pump through a switch.
