![]() ![]() That was an excellent find, absoutely brilliant! Thanks.This one should be book marked for future reference.ġ] install a piece of metal inside the tube that has an over hang, something that the top of the clip does not contact, to break water tension. The good news is that it is not a gasket problem or a damaged flush tower that I have to replace. I liked the flush results and just kept it high, but the clip for the refill tube causes drawdown in the tank. You could actually see the surface tension of the water above the riser. The tank was factory set with the water level set to the very top of riser. The AS Champion 4 does have a note within the tank that says to set the water level 1/2" below overflow top. The flush within the bowl is also acceptable. I set my water level yesterday at 3/8" below the riser and no drawdown begins and the water level is held. This produces a poor flush even for liquid waste. This situation does not waste water by continually topping off the tank, but the drop of the water level (caused by the clip siphoning water) takes it down to 5/8" below the riser. ![]() My valve seems to need about a 1/2" drop before it activates. If the water level is set above the 3/8" mark, then either one of two things:ġ) if water level is set very high (near the brim of the riser), then water will drop far enough to activate the water valve and the tank will refill on a regular basis (in my case a cycle of about every 30 minutes),Ģ) if water level is set 1/4" below the riser, then a drawdown will still occur and tank level will drop to 5/8" below the top of overflow riser but the refill water valve does not activate. If I set my tank water level to 3/8" below the top of the overflow riser, then the siphon (or wicking action) caused by the plastic clip does not occur. The pictures show the water drawn up from the tank and the tiny stream flowing down inside of the riser overflow. The drawdown in the tank will continue to about 5/8" below the brim of the overflow riser. I moved the clip to several different locations around the top of the riser and could see the tiny stream of water following the clip location. I was able to track a tiny stream of water flowing down the inside of the riser from the plastic clip. I further watched the overflow tube after the tank was full to see if the plastic clip (holding the refill tube) was drawing up water and over the overflow riser. I tried to see if there was a vertical crack, but I couldn't find anything. Any suggestions or input on another source for the leak (instead of the common blue gasket location) is greatly appreciated. I just want to find the source and fix it and be done with it. ![]() The Champion 4 flushes great, but the leak is a hassle that started only 2 weeks after install and is very annoying. Has anyone seen this before, or have any other good ideas as to where the problem is occurring? AS is now sending a replacement flush tower. I wouldn't think the water pressure would have that much influence, rather than the water continuing to drop to the source of the problem. The refill tube seems fine and I haven't seen any water entering from a crack in the tube, therefore I'm assuming it must be the gasket on the bottom of flush tower or maybe the thumb screw on the top of flush valve? I'm surprised that the leaking stops well above the source of the problem. I've let it sit all day without any further drop below this point. I've seen it drop 1/2" in about an hour, but it will always hold between 7" or 7 1/16" depth consistently. The depth of water in the tank will lower to about 7" deep (well above the rim of flush tower) and hold (no more noticeable drop). I've turned the water supply off several times to try to pinpoint where the leak is occurring (above or below the rim of the flush tower). I replaced both gasket and o-ring, but neither of the original materials seemed damaged. AS sent me a new blue gasket and o-ring for the thumbscrew on the top of piston. The installation went fine but 2 weeks after install it started leaking. I installed an AS Champion 4 about a month ago in my home.
