Works Very Well
on January 2, 2013
We installed this toilet fill valve after noticing an intermittent drip from our hot water tank's temperature and pressure (T&P) relief valve. We began noticing that the hot water tank would usually drip a few cups of water shortly after using the shower, washing dishes, or washing clothes with hot water. I purchased a water pressure gauge from a local hardware store and attached it to the drain of the water heater. Normally our home has water pressure of about 50 PSI. When the tank was dripping, it was up to 135 PSI. Since we have a check valve just off of the main water line, when our hot water tank started heating up the cold water, the expanding hot water had nowhere to go and built up high pressure in our pipes. The only place this extra pressure could be released was through the hot water tank's T&P valve.
We also had problems with faucets leaking and fixture seals wearing out quickly, and the toilet would randomly run without reason. These problems were also side effects of the high water pressure we were seeing. The high pressure was looking for some way to escape, and that usually manifested in a leaky kitchen faucet or dripping hot water tank. Usually, a thermal expansion tank is installed to correct these problems associated with the high pressure caused by heating the water. However, we did not really have a good place to install the expansion tank, and it would have also required us to call in a plumber. At the time, the cost and labor to install the expansion tank was an extra expense we couldn't afford.
After doing some research, I found the Watts Governor 80. This toilet fill valve has the unique feature of a built-in pressure relieve valve. When the water pressure goes above 80 PSI, it releases the excess water into the toilet tank, thus lowering the pressure in the pipes. It saves the pipes, faucets, washing machine, and water tank from excess wear and tear due to high pressure and stopped our water tank from leaking. It has also stopped the random leaking faucets and running toilet as well. I had concerns that this fill valve might be constantly letting excess water into the toilet tank and wasting water, but I haven't noticed this at all. It seems to let off just enough pressure when needed, and I've only once heard the fill valve letting off pressure for a brief moment in the month that it has been installed. It really does act as a normal fill value with no additional noise or excess running, but it's silently working in the background to relieve pressure in the pipes, and that's the beauty of it. This is definitely a much cheaper solution than calling a plumber and installing a thermal expansion tank, and it has completely resolved the problem with our dripping hot water tank in the one month that it has been installed.
Installation was very easy and the included directions were clear. There's also a video by Watts on YouTube, and on their website, showing step-by-step directions on how to install the fill valve. This was my first attempt and installing a fill valve, and I was able to successfully finish the job in about 35 minutes. The fill valve also has some other good features. It has built in leak detection, which prevents the toilet from constantly running if there's a problem. And you can also adjust the amount of water entering the bowl when flushing to help prevent against wasting water. This product also came with a new flapper as well, so it's basically a toilet repair kit.
Overall I am very happy with the Watts Governor 80, enough so to write a few paragraphs on something as common as a toilet fill valve. It has completely resolved the issues with the hot water tank dripping, our leaky kitchen faucet, and running toilet, all at a very affordable price. A 5 star product and would definitely recommend it.
