I am trying to solve a problem with a 20 yr old Kohler that won't hold water. 3 attempts at replacing the flapper were no help. Since there is no water on the floor, I decided that I needed to replace the flush valve and seals. I picked up a "FluidMaster" flush valve, new bolts, rubber and brass washers and nuts, and the Kohler 3-corner gasket (GP51487) for the tank-to-bowl connection. After figuring out how the 3-corner gasket worked with its long rubber sleeves for the tank bolts expanding to create the waterproof seal for the bolts, I installed the flush valve. The instructions say to hand-tighten the Spud Nut, then add a half-turn with a wrench. I had nothing with big enough jaws to grab the Spud Nut - plus the 3-corner gasket obstructs easy access to the nut. So - I hand tightened the flush valve but noticed that it did not feel fully seated against the tank bottom. I removed it and reinstalled and 'massaged' the flush valve bottom into the tank's flush hole and obtained a better set. I hand tightened and then used the flush valve tower to help me get another half or ¾ turn on the Spud Nut. I then reinstalled the tank, filled it halfway, and marked the waterline. 20 minutes later nearly half of the water had disappeared. I removed the tank and repeated the exercise with seating the flush valve. This time I set the tank on a sink and half-filled it. I thought I had succeeded but then noticed about 1 drop every 3 seconds coming out of the center of the flush hole - visible underneath the tank as it was sitting on the sink. So I then went back and tried two more attempts at sealing the valve bottom to tank - but only made things worse. Now my question is - what else can I do? I'm afraid to find a wrench and cinch the Spud Nut tighter for fear of damaging the rubber gasket or the tank. Is there any way to add another sealing gasket or O-ring under the flush valve to improve the seal? I have some photos available at this link bit.ly/KohlerTank Any help would be greatly appreciated!

We have a Grohe Eurodeck 33-896 kitchen faucet (single lever, pull out sprayer) which is apparently clogged up somewhere. I already took apart the sprayer and aerator, it's clean. I called Grohe yesterday and someone there told me that my problem is a flow restricter in the hose's swivel connection. He said I should take it apart and probably drill out the plastic flow restricter. (We have lousy water pressure anyway, being at the top of a hill) Well, I love solutions that involve power tools, so this morning I started work. Well, I can remove the hose from the swivel, but because it is a swivel, I can't unscrew the swivel connection from the mixing tube on the underside of the faucet! Does anyone know how to get one of these off? Thanks, Mark
