Does this assembly include a flush valve wrench?

Asked by: cdmm
Yes it does. Visit American Standard on line to see their very nice tutorial on how to change the flush mechanism. You can see this white plastic wrench. It works quite nicely. Remember, it's plastic and not titanium so you should hold it on with one hand as you tighten it with the other. You'll know when it has been tightened enough. Rough in by hand and then give it another quarter turn with the wrench as it tells you in the online tutorial.

Is there a replacement flush valve shorter than 4 inches?

We just purchased 2 Campion 4 toilets. One is installed and we are not satisfied with the flush at all. There is no way this flushes a bucket of golf balls! The problem seems to be not enough water being released to accomplish the job. Since the valve is 4 in. high from the bottom of the tank, there is 4 in. of water sitting there doing nothing. Is there a replacement valve shorter than 4 in. to allow more water to flow? Also I notice the valve on the 1 pice toilets is much lower, is that a possible replacement I can use?
Asked by: Anonymous
I don't think so. This assembly is made to use with the traditional taller tank. A lower tank as found on one-piece toilets does not provide enough 'height' to generate the water force this assembly was designed to work with. You may have noticed at the bottom of the toilet that there are TWO large openings for flush water. The muscle for the Am. Std 4 toilets occurs when the 1.6 volume rushes in through the opening facing your feet to get everything moving through the rear. That's how the magic works. Increasing the height of the mechanism (Raising the green tower) will not improve the efficiency of the assembly and may, in fact, reduce it.

Is there a replacement flush valve for the 4 inch flush.

Asked by: john
Yes. Check on line. The complete unit sells for around $30 and is worth it. It arrives with a blue gasket seal. I recommend buying a second (spare) one for use down the road. The gasket and hardware to fasten the tank to the toilet are usually not needed but are also available from Am. Std. if you need them.

Champion 4 Flush Valve Assembly is rated 4.2 out of 5 by 82.
Rated 1 out of 5 by from don't get a full flush new design uses less water because it sits 3 inches off the bottom of the tank so you have all that water that is not used in the flush. had to glue a 2 1/2 in piece of pipe on top so I could adjust the water level to get a better flush. am not at max water level and still don't always get a good flush. used to be a great toilet, now it's a piece of junk

Rated 5 out of 5 by from Champion 4 Flush Valve Assembly We have not had to install product. We cleaned the one in the toilet and put Vaseline around the lip and it stopped leaking. When we ordered the product our toilet was leaking and you could not buy a new one at any had to be ordered. So we ordered it and expected delivery was 7 days. So we cleaned it as stated and waited. The product was received in 4 days...but the toilet no longer leaks...we've put this up till we need it in the future. Thank you to Home Depot for the prompt service and the lower cost than other places.

Rated 5 out of 5 by from Great Fit This was a replacement part ordered for the Champion 4 toilet and fit like the old one. Not too bad of a job but had to remove the tank from the bottom to install, but knew I had to do this prior to the order. The main thing is that it fixed the problem of ghost flushing.

Rated 4 out of 5 by from Must have replacement Easy install with reasonably good instructions, although they did not match the product perfectly. In terms of performance, the flush works well, but it helps to hold the handle down for a heartbeat to get the full effect. This part is so much better than the original that I wish they had found some way to tell me about it. I would have done the replacement immediately.

Rated 4 out of 5 by from Champion Toilet Renewal For several years our Champion toilet has had problems with the flush valve always clunking and occasionally slipping and not flushing the toilet. I recently researched the valve and discovered that they had completely changed the mechanism. On receiving the replacement valve, I proceeded to install it and wound up with a leak, which had nothing to do with the flush valve, but was due to failing to replace the tank to bowl gasket. A trip to Home Depot for the $4 gasket, and the leak was fixed. The toilet now works flawlessly, however, the only small problem with the new flush valve is that it is much harder to press the handle to flush the toilet.

Rated 3 out of 5 by from Brand specific Need special rubber tank to toilet seal ring to work right otherwise it will leak, for the price it should come with one.

Rated 1 out of 5 by from Not so good Mine used to work, but it recently started leaking so the tank would try to refill every few minutes, and I discovered that the neoprene gasket on the flapper had gotten a tiny bulge in it that was full of water, and when I tried to replace the flapper after puncturing the bulge on the gasket with a pin, the whole flapper didn't go back together sufficiently, and the tank leaked worse than when I started my repair.

Rated 2 out of 5 by from Consistent Problems This toilet worked well for a year then failed very quickly. Seal leaked, replaced it twice. Finally replaced the entire flush valve assembly and that was the only way to get the leaking stopped. You can't buy any replacement parts for it at the store, have to order on-line. Just a bad product all around and a bad experience. Would never buy another even if they were half the price.
