It's worth it's money just purched it again

I would have given this proven circulator five stars, but was disappointed by the poor packaging. The fairly heavy circulator was shipped loose in its original half open cardboard box without any stuffing protection. The cardboard was floppy and had lost all shape, so no protection there either. As a result the cover for the electrical box was bent. Not the end of the world, just a suggestion for the seller.

Let me preface this review by stating that today is Sunday and I ordered this pump at 10:44 this morning. It was on my doorstep before 6:00 this evening, which I think is pretty good for a six dollar fee.

I installed this pump as a replacement for a Grundfos UPS 15-42F. The old pump was damaged when the hi-limit on my aquastat went out and caused my boiler to overheat the system. I realize that the curves of these two pumps are quite different, but this unit was all that was available for same day shipping. With overnight temps in the twenties and an infant in the house, I just needed something to push hot water through my baseboard radiators.

This unit works exactly as advertised, but there are a couple of things that aren't quite as nice as the Grundfos it replaced. The first thing I noticed was the noise. It is basically a non-issue as this lives in the basement, but I can hear it over the boiler when I am in the room. When the Grundfos was on, I had to put my flashlight to the pipe and my ear to the flashlight to hear the pump running. That being said, the Taco runs at almost double the RPM, so it is basically a null argument. The other thing I liked about the Grundfos was that the bolts were entirely captured in the bolt holes. This Taco unit only has ears on the flanges. This was only mildly unsettling because the Taco is about 3/8" of an inch shorter than the Grundfos. However, once aligned and tightened down, it shows no sign of leaks.

I would not hesitate to recommend this pump to anyone. Taco seems like a good, honest American company with a solid reputation. The build quality seems to be in line with other pumps in it's class. I hope it provides me with many years of service, and I hope it does for you as well.

Everything fit perfect and worked out great

Boiler radiant heating system went down last winter and repairman said it was bad pump....wanted $1700 to fix....couldn't afford that so had him wall off that pump and we lived without that zone for rest of winter while saving for repair....then I began looking into doing repair myself

The Taco pump replaces the exact same item that failed...info I found on web said that is always good idea. Part was listed at $700 by repairman....I got for just over $100 from Amazon....so savings are huge just for part. Works great so far and shipping was quick.

As for install....well trial and error was the key.

I couldn't figure out how to keep air from getting in system during install.....there is some kind of a a switch or intake valve I just couldn't find....and right after install (very easy step) the pump knocked badly and then wouldn't seem to work....(I think it was "air bound") I finally tried draining the water & air in just that zone and tons of gook came out along with the water....then let boiler send water to just that zone...and it worked....opened up all the rest of the system valves and now have heat throughout

As you can tell I'm a non-expert handyman....but willing to try. The Internet has great information....and even though I couldn't understand all of it at first...through good old trial and error I figured it out and saved $1500. Need to understand what each pipe does in system to make it work (feed vs returns). It took a couple of days but was well worth it.

Good luck
