MY PROBLEM IS WITH THE FLOW OF HOT WATER IN THE KITCHEN. THE FLOW IS DOWN TO A TRICKLE. THE COLD WATER PRESSURE IS GOOD IN THE KITCHEN. THE WATER PRESSURE ELSEWHERE IN THE HOUSE(HOT AND COLD) IS GOOD. I HAVE TAKEN APART THE FAUCET -- A SINGLE HANDLE MOEN -- AND CLEANED ALL PARTS. IT DID NOT MAKE A DIFFERENCE. WHAT DO YOU THINK?

We've got a large bathroom with the standard 5 plumbed structures.....one toilet, one bathtub, one shower and two sinks. When I was up on our roof yesterday, I counted three separate vent stacks over the bathroom, each where they should be. I'm assuming that the toilet has it's own vent, the two sinks share a vent stack and the tub and shower also share a vent stack. Is this a fair assumption? My main question is this..... Is it possible/feasible that all three vents are somehow connected to each other even though there are three separate vent stacks popping thru the roof? That doesn't seem likely. The reason I ask is that we've had an ongoing problem with a sewer smell eminating from the shower drain for quite some time now. I've snaked it, DrainCared it, bleached it, scrubbed it and tried a myriad of formulas in it, all to know avail. A few days ago OldGuy suggested that maybe all share a common vent system and we may have a partially plugged drain somewhere in that system. So I followed his advice and climbed the roof and jet hosed water down each vent stack in hopes of clearing any obstructions. Still got that nasty smell. It is worse at some times than others, but just won't go away. We're at wits end. Any ideas, comments are always appreciated.......
