Last week we had some guys come and put in a new gasket in our bathtub and put new flooring on the floors. They had to turn the water off at the toilet to remove the toilet. Well, ever since that day, whenever it's been a while since we flushed the toilet, and we flush it, the pipes makes this loud vibrating noise. It's horrible. We've had one of guys come out and take a look and he doesn't seem to know what it is. He THINKS it's this valve in the basement. He says that we really don't need this valve there to prevent the water pressure from flowing back, but that some townships require it, even if you don't need it. He said he could replace it and the piece would be $120, or he could just replace it with normal piping. He also says that nothing they did could have caused that problem, and that a valve usually lasts about 8 years. and of course that's how old my house is. I know it's hard to understand if you haven't heard what I'm talking about. But, everything was just fine until they came here. One of the guys is my Best Friend's Father in Law and I used them because I thought I wouldn't get ripped off. I did have to leave for about an hour when they were here to pick up my child. Is it possible that they did something to my pipes purposely? I am very upset because my husband and I are completely clueless when it comes to this stuff and we are HUGE targets to get taken advantage of. That's why I like to go with people we know. I'd like to think they aren't messing with us, but seriously... I lived in my parent's house for 20 years and I don't remember anything like that happening. Oh and to add, I've tested it out, and I really don't think it's even the valve. When I feel the valve when it makes that noise, the noise sounds like it's coming from the pipes closest to the toilet. I will say that when my Best Friends Father in Law came to diagnose the problem with the bath tub, he was very thorough and I felt very secure with his ability to fix my problem. I did mention to him that I wasn't secure with the thought that it was the valve causing the problem. The noise also occurs when I turn the washing machine on, and sometimes when I turn the sinks on. It only occurs if it's been awhile since the last big flow of water. Sometimes 30 minutes or so. Any help would be GREATLY appreciated. TIA ~Aileen

I've started to build a shower stall in our basement.(1st time) There is a subfloor over concrete,I am going to hook up drain to existing line. I'm using a metal pan for the base, then mortar & tile. Since I don't have access to hookup the drain, I was looking at the "slip on" type. Does the drain go flush with the tile? How do I attached the drain to the metal pan and what height do the drain stand off the pan? Anyone direct me to a detail of this, or suggest another type drain. Cheers Jon
