Hayward TriVac 500 Not Moving: How to Fix

The Hayward TriVac 500 is a really underrated pressure side cleaner and it is pretty trouble-free also. But if you find that it is moving very slowly in your there could be a few things wrong with it, including a bad Timer Valve. It is an easy part to replace and they sell a complete kit – the Hayward TriVac 500 Timer Valve Kit #TVX7500TV For $135.00.




Check System First:
Because of the nature of how a pressure side cleaner works, check to make sure both the system pump (main pool pump) and the booster pump (cleaner pump) are set to come on at the same time. The main pump if it is a VS pump should be running at a higher speed, around 2200 RPM or greater is acceptable. If the system pump and booster pump are not set to turn on at the same time the TriVac 500 will not move.

Check the Quick Disconnect:
Make sure the TriVac 500 has enough water going to it. Sometimes the pressure relief valve is open or cracked. Typically, it should be closed if you have a ¾ hp booster pump connected to the TriVac 500. Also, check the debris screen in the line to make sure it is free of debris. When you clean your filter or if your filter grids or cartridges have tears in them, debris can get into the booster pump line and clog up the screen. If the screen is clogged the cleaner will not move.

Check for a Jammed Wheel:
Sometimes debris will get stuck in such a way as to jam one of the TriVac 500 wheels. It doesn’t happen very often but a trig can get stuck in a wheel and keep the wheel from spinning. So make sure all the wheels spin freely.

Timer Valve:
When you open the TriVac 500 you will be surprised at how few parts are in this thing. Basically when you replace all the parts that come in the Timer Valve Kit #TVX7500TV you have essentially put new guts into the machine. I don’t recommend replacing one part here or there. The kit will pretty much cover all of the bases so there is no need for individual part replacements. Hayward made things easy by creating this kit.  If you have checked the above things and the TriVac 500 is still not moving chances are that replacing the parts in this kit will fix it. 

While you are at you can also change the bearings in the wheels along with the rubber tires. This will basically give you a brand new unit. I found the TriVac 500 very easy to work on and I like that Hayward kept things simple with their pressure cleaner. You can easily do all the repairs yourself.

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
