Even last-minute plans can come together

The previous unit (same model) lasted at least 15 years, new unit has better design for the housing, so it will probably outlast me.


Refurb units at discount might be attractive.

Great pump

Friday, January 04, 2013

I really can't say anything bad about this product. I have a very old hot water boiler system heating my home. My old Series 100 developed a leak. I'm sure it was about 40-50 years old. This new pump is a direct replacement. Installation was easy. I know there are alternative pumps that cost much less but after seeing how long my original one lasted, I had no problem replacing it with the same type.

The price could be better but again, after seeing how long it lasted, I'm sure the higher price will wash out when other pumps fail earlier.

I was shocked when I visited my local dealer and found out this model was selling for $545.00. After just a short google search I found the same model and warrantee on for half the price! The site was easy to navigate, checkout was quick and delivery was on time. Thanks Drillspot for making a bad situation better!

Ease of install

Match the original electric connection which is located on the bottom of motor not top

Great Pump

Tuesday, January 31, 2012

This pump works great and is so quiet you can barely hear it run, the one it replaced was very old and noisy that rattled my pipes. UPDATE: pump made it 24 days before becoming so noisy it woke me at 2:30 am out of a sound sleep, took apart and found pump is very stiff barely turns. Was oiled when installed as per instructions, unit is now made in china like everything else and is apparently junk.

Circulator Pump

Received on time. Pump is just like the orignal. Fit perfect, and is running good. Put the new one in a week ago that i had sitting for 6 years then a week later the other one went out, and the one I ordered from Drillspot did not get to sit very long. I have a 2 pump system. Hopefully I should be good for a few years. By all means, the price was right. A big savings compared to local dealers. You can feel safe dealing with Drillspot.

Just what I wanted

I have been very satisfied with 100 circulator pump. The one I am replacing is the same pump. It has been running continuously for many years. It is my fault that it stopped running. I failed to oil it on time.

Purchase this to replace a Bell and Gossett pump that never worked in my apartment building when I purchased it 8 years ago. Replacement was easy and everthing aligned exactly. So far the the pump works great!

I was pleasently supprised when I saw this was so recently manufactured. At such a cheap price, I was expecting old stock or something.

It's a great pump at a great price.

The oil containment could be improved. Of course, I probably over oil it.
