How to Plumb in a Jandy VS FloPro 1.0 HP Variable Speed -Tips

In this article I go over plumbing in a Jandy VS FloPro Variable Speed pump. Plumbing in a pump may seem daunting but it is actually quite easy. This particular install is in a very tight equipment area and is one of the more difficult plumbing jobs you will encounter.

To see a step by step plumbing installation, including removing the old pump watch this video:



A disclaimer here, most manufacturers including Jandy will void the manufacturers' warranty if the equipment is installed by the homeowner and not by a pool service professional. Pentair and Hayward have the same policies as well. I don't agree with it but it is what it is. Chances are
you will never need to use the warranty anyway, but be aware of this policy before you do this yourself. So this video is geared towards the pool professional and use this as a guide.

The first thing to note is that the FloPro is designed for 2” plumbing. If you have 1.5” plumbing you will just need reducers at both unions and use all 1.5”couplings and elbows as well as PVC pipes. Not a big deal really. If you have 2” PVC pipes you are good to go.

The base that comes with the FloPro makes it one of the easiest VS pumps to install. It will match up the FloPro perfectly with the inlet pipe so if you are on a cement pad this is ideal. The outlet will line up also in some cases, but in this job I wanted to move the pump back so I could easily access the panel in back to wire the pump. So you may need little plumbing or extensive re-plumbing depending on your set up.

A bit on PVC Cement and Primer. Primer is a good idea to help make the fittings easy as it melts the pvc slightly and also helps with the PVC Cement bond. I the Pool Heavy Grey PVC Cement as it dries slower allowing for more time to play around with the fittings. You will find the blue standard PVC Cement dries very rapidly giving you no room for error. If your new to plumbing use the Pool Heavy PVC Cement.

I use a liberal amount of PVC Cement and apply it to the fitting as well as the pipe, if you try to get fancy and use too little chances are the PVC will start to leak on start up. So I recommend to be very generous with the PVC Cement so that you are not re-plumbing it a day later.

With the included unions attaching the pump to your PVC fittings is very easy. Just be sure to measure exactly – go 1 1/2” into the coupling or elbow and 1 1/2” into the unions on the pump. This will give you a nice snug fit. When attaching the unions there is an o-ring inside so make sure the threads are lined up perfectly, otherwise air will get in and the pump will not have full power and may have trouble priming. If you notice this after turning it on, undo the unions and align them again for a tighter fit.

I like to let the PVC Cement dry for 24 hours. Overkill in most cases but this will assure that you don't start the pump too soon and thus ruin the bond. This is the best and most cautious way in my opinion.

Just be sure you have enough PVC pipe and fittings before you start the job. I always like to have at least double of what I need in case I run into a problem. It is really pretty easy once you do it and if done correctly there will be no chance for any leaks.

Here is the PVC Cement and Primer I recommend you use: 


You Should also have some PVC Couplings and Elbows on hand:

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...
