TEFC Pool & Spa Motors

TEFC motors are relatively new but I think will become the norm in the Pool & Spa Industry. The TEFC motors provide superior performance and longevity over traditional open drip-proof (ODP) motors. Their Innovative hydraulic design and thick-walled body parts deliver super-quiet operation. The fact that they are completely enclosed means that they are also extremely weatherproof.



Many manufacturers make TEFC motors and the common features are:
Finned Aluminum Totally Enclosed (TEFC) frame keeps windings and bearings drier, cleaner, and cooler.

Top-mounted conduit box is easier to access in tight spaces and better protected from weather, making this one of the easiest motors to install on the market.

115/208-230 Voltage rating for poor power quality areas and the ability to change the voltage at the flip of a switch.

In this video, you will see the Jacuzzi brand and they feature both a Square and Round Flange so they are compatible with Hayward, Pentair, Jandy, and other manufacturers.

Here is more about the Jacuzzi models:
Jacuzzi TEFC 1-HP- 2HP Squared/Rounded Single Speed Pool Motor provides superior design and technology for in-ground swimming pool pumps.

Pool Motor Features:

TEFC motors will be the standard I think moving forward in the next few years for both VS and any single-speed pump. I really like the quite operation of these pumps and you can really hear a difference when one is running versus the old versions. I also love the top mounted wiring. If you have ever replaced a motor, you know what a pain it is getting to the wires on back. Especially if you are in California where everything is up against a house or a wall. The top wiring configuration is great! 

It really comes down to the fact that TEFC motors will last longer and are ideal for all swimming pool and spa applications.

Can I Use Clorox Bleach in my Pool?

Image
Regular Unscented Bleach I started doing pool service when I was 16 years old back in 1988. I took a break from the industry and did some Real Estate Investing and ran a small business for awhile. But I always loved working outdoors and so I decided to do pool service again. So I have about 15 years of practical experience in the field. My specialty has always been water chemistry as I was formally trained by an experts in the field. So I am well versed in most of the chemicals that are on the market today and I have used and tested a lot of different products. So when you hear those in the industry discourage and even slander anyone who uses bleach in their pool, you may think that it is not a product that you should use. In fact as you read this article you will find that using bleach and only bleach is a safe and smart choice. There is a lot of ignorance surrounding household bleach and the use of bleach in a swimming pool. Here is a video I made that goes in more detail on usin

Mr. Pen Non-contact Voltage Meter - Don't Get Electrocuted!

Image
One of the biggest issues you will run into with anything connected to an AC power is if that device or equipment is receiving power. In the pool service industry, this often is the case when you find that a pool pump won’t turn on. Or if a pool timer doesn't on, is it receiving power? Also for repairs with so many breakers being unmarked, how do you know you turned off the right breaker. Bottom line, a non-contact detector like the Mr. Pen is an easy way to see if power is going to the equipment/device and the line is active. A non-contact voltage detector is just that. You don’t need to make contact with the line like with a Multimeter. Plus you don’t need to adjust any settings or knobs to get a voltage reading. Simply hold the Mr. Pen over a cord or wire whip and if there is AC power a red light will turn on and an audible beep will come out of the device. A very easy way to tell if power or a current is present.  To order: https://www.amazon.com/dp/B092LFYTG5?&_encoding=UT
