Taco has been making this type of value for years but this control head just does not hold up. My HVAC guy tells me he has had to go to a different value on his geothermal instalations. My first value head failed after three years and my second one in three months. My HVAC contractor is now using a black plastic value that looks like the ones on my yard irragation. Please stock them.

On open loop geothermal. These last me about a year. that's it. I just switched to the electric motor actuated ball valve from Taco. Hopefully it lasts longer.

Comments about Power Unit for 5101-G2:

This valve was installed on my heat pump a few years ago. Have had to replace the power unit 3 times in 5 years. Seems like the valve operates but the switch or sensor inside does not change state, shutting down the heat pump and the backup heat. Need to keep a spare.

this operator is an exact replacement for the original equipment operator at a considerably lower price. I recommend it to anyone in need of an operator.

Critical component in my system

By JRL

from Clemson Sc

Comments about Power Unit for 5101-G2:

I use the valve to open the 1" open loop source line to a Water Furnace heat pump, especially to reduce water hammer, because my well pump maintains constant pressure. When I first installed the heat pump, a standard solenoid valve cause terrible water hammer. Tried other so-called slow opening valves, but they did not stop the water hammer.

This power unit needs replacing every couple of years. Valve body has stuck after ca 3 years, but the moving parts were easily replaced without replacing the entire valve. But I know of no alternative. Works well otherwise.

Power unit track record is poor at best

By Ed B

Comments about Power Unit for 5101-G2:

When it works, it is fine. I've had several that fail after a couple of years, and have had one that didn't work (tested by a professional) right out of the box. Problem is that there aren't any good alternatives for a geothermal application.

    Q:

    What is the warranty time frame for this valve? I too have had multiple failures of this valve. My current application has this valve mounted horizontally on vertical pipe and I have replaced 3 valves in the last 2 years.

      A:

      I've had this valve for over 2 years with no problems. However, it is mounted vertically. I'm wondering if your horizontal mount is contributing to the problem?

      A:

      Don't know if it has any sort of warranty ... I would suggest the valve
      be mounted on a horizontal pipe run with the power head on top so that
      any possible leakage from the valve has less potential to allow
      moisture to get to the power head.

      A:

      I can , It looks familiar.
      Mine are mounted horizontally. I don't think it makes a difference. Mine are
      on three water source heat pumps. I have never asked about a warranty.
      I usually can get two years out of the solenoid part of the valve. The brass
      valve itself last a lot longer.

      A:

      I am not sure on the warranty on this product. I have two of these
      installed in my house (also horizontally on vertical pipes) and have
      replaced only one of them once in the 9+ years I have had them in
      service. I do keep an extra on hand though just in case.

      A:

      This is only the second failure I have had. I do not know what caused
      it. In fact, I am not really sure that the valve I replaced is bad as I
      have the feeling my system is not sending the proper signals to it.
      Overall, I have had good luck with it. Make sure you are getting the
      proper voltage and also make sure that the valve itself moves freely and
      is not mucked up with calcium or iron. Tony

    Q:

    Hi! What is the difference between this power unit and the Zone Valve Power Head (Series 570)? I am having a high failure rate with this power head and am looking for alternatives.

      A:

      This is the power head for Taco's geothermal/open system zone valves. Unfortunately, heads for different series cannot be used interchangeably.

    • VERIFIED BUYER

      A:

      It depends on what is causing the failures, mechanical or electrical. In any
      case though, this valve is for geothermal applications and has a special
      "slow-closing" actuator required in geo applications. Are you using it for
      heating water? That might cause a problem.

      A:

      They are one in the same ... I too had lots of problems with this power
      unit and I've replaced it about three times in the last 8 years or so.
      Eventually I replaced the valve along with it and I hope that fixes the
      root of the problem. Thinking the valve packing may have experienced
      leakage at times leading to moisture in the power head and failures.

      Answered on 3/9/2012 by Another PexSupply Customer
    • VERIFIED BUYER

      A:

      There are several versions of the Taco valve. The one I currently use to control water input for my geothermal furnace is 555-173RP. I suggest not using any version that does not specify that it is for geothermal use. Other versions that I have tried have failed in a year or less. This one has so far worked fine for a year and a half (knock on wood).
