I have a toilet that occasionally runs slow. I.E. it fills up, and slowly spins and drains. It'll remain like this till I take a plunger and give it a plunge. Then it will run normal.

It has happened twice. The first time it happened only with liquids in the toilet. The second time, it was after solids. It's a Kohler Cimarron. I've only had the toilet 2 weeks.

I just had my house significantly replumbed for the drain lines. New vanitiy sink, with it's own vent line. (No drains in the house had vents, other than the main soil stack.) The kitchen sink was vented as an island. New toilet, new washer hookup (none existed) .I provide this because I felt you need all the info, just in case it's related. (It's town sewer BTW).

Before I call the plumber back, I'd like to have an idea of what I should tell him to look for. I've already had him back for a stupid thing. (Sediment in filter screens gave me low water pressure in a couple of sinks) So i don't want to call him back for something else, and have it turn out to be something simple.

mp, a toilet flushes much better with a high water level in the tank. raise the water level to just below the overflow tube 1/4". also, adjust the yellow foat on the flapper closer to the flapper so the toilet has an extended flush. more water evacuated from the tank.

Can't. The water level is there already.

Also, holding the flapper open so the tank completely drains seems to have no effect when it's like this.

When I was the trouble shooter for a large plumbing company we used to get calls like yours. "The toilet does not overflow; the water reaches the rim and gradually subsides, leaving the waste and a small amount of water in the bowl."
As a rule in older toilets this would mean a blocked jet butI was getting these calls on toilets that we just installed in our new construction. So when we got a complaint that one of our new toilets was having a flush problem I went out on the call. After a few calls I found the trouble. When our installers set a toilet the wax ring would spread in instead of out. This choked down on the opening setting up a back pressure that stopped the siphon action of the flush.
The remedy was to pull the toilet and form the wax seal so it beveled out and would spread out instead of in blocking the drain opening. I would have this checked first. After our plumbers began to bevel the ring out out the complaints stopped. Hope this helps, Tom
