It stopped filling the tank at all. Ck'd water inlet ok-went through it from top to bottom. Could not disconnect it from the tank. Two of us has been wrestling with it. Went on web site NEVER received a response.

I replaced 4 leaky fill valves with this product in my "new" home about 5 months ago. 3 of them seem to work well. The 4th has started spouting water out of the top. It still flushes and fills fine as long as you don't take the lid off. Then it acts more like a bidet. If you install this, check it periodically. Needless to say I will be replacing this today. The only other con is that they have all recently started making "whistling" sounds.

Ask This Old House does not recommend just any old product. I installed two units in less than 30 minutes. I have high hopes for savings on my water bill. My existing toilets are early technology low-flow systems and I have repeatedly heard that they are inefficient and require multiple flushes per use, which has been my experience. I hope the dual flush option will conteract this dilemma.

I installed three Hydroclean and Hydroright conversion and water saving kits. The first one took better than an hour, but the second one went on much faster. I just installed the kits so I have no history on whether I am saving water or not.

This review is long, but if you’re considering buying this valve, it’s worth your read. I was amazed and happy about how much this fill valve was going to save me on wasted water down the toilet drain. The install was easy and the valve seems well designed and engineered. I measured the amount of water my toilet was wasting with the full open "mini-valve" and I collected almost a whole gallon of water that would have otherwise gone down the drain. I read from the water meter to compare how much water was used during each flush with the mini-valve wide open, and with it in the optimal position per the instructions. I went from a 4.5 gallon flush to a 3.5 gallon flush. Wow!! Or so I thought. Since the valve I replaced was broken, I didn't measure the amount of wasted water before the new hydroclean. But wait, I have 2 other toilets of the same exact make and model. Both with the older valve. I measured the amount of water per flush by reading the water meter. (the most accurate way) The meter reported that the flush from the other toilet used 3.5 gallons. That's right. The same 3.5 gallons that the toilet with the new calibrated hydroclean valve uses. I learned that the hydroclean valve will actually use more water when the mini-valve is in the default position of wide open. So when you get to physically turn the lever back on the mini-valve, your tricked into thinking that you are saving all this water, when in fact you are just preventing the valve from putting an extra gallon down your toilet drain. I also watched the fill cycle on my other toilet with the old valve and the bowl and tank finished filling at approximately the same time. I may have heard a few trickles of water fall down the back of the bowl, but it definitely wasn’t a gallon like the hydroclean had led me to believe. I also observed a 40 year old toilet at my work, and it also filled the bowl in the same time that it filled the tank. At twice the price of the other replacement valves, I feel angry that I believed in the hype. Also, they made the valve to give off a louder than usual sound when it does a ghost refill when the tank level drops enough due to a leak through the flapper. While this is great for alerting you that there is a leak, it is not so great when every time you flush the toilet, it sounds like your toilet is going to break. Anyone who hears it will not think your toilet is acting normal. It’s very loud and annoying. I’m all about saving water, but when my old valve used the same amount of water, and it was quiet, it makes no sense to buy the hydroclean valve. Oh wait……if you want to spend twice as much money to get a valve that squirts extra water into the bottom of your tank to break up some of the rusty settlement, then go ahead. I’d rather clean the tank myself. There may be other toilets that can benefit from this that are really throwing extra water down the bowl, but it sure wasn’t any of mine. And it wouldn’t help the 40 year old toilet at my work either. Be sure to check your fill cycle if you decide to buy. If you really want to save water, then your best choice is to buy a new high efficiency toilet. Otherwise, my advice is to just buy the cheaper, simpler, and quieter fill valve on the shelf.
