No water coming from hot valve on faucets
Experiencing at times (more frequent lately) that when we turn on the hot on faucets that no water pressure. cold is just fine. sometimes there is a noise like rattling at the water heater and then the hot water starts to come through. i took off the incoming flexible copper tubing and noticed a ball valve (plastic) and tried to push it down. using a flat screw driver with a little more force it pushed down. I put the tubing back on. turned incoming valve on and it seemed to work as hot water was now coming out. it did almost stop again but something seemed to give and works for most part.
i did notice that the cold water intake copper tubing gets a little warm, not nearly as hot as the hot outlet tubing. curious about two things:
1. what might be causing the hot water not to have pressure.
2. since i pushed (opened) the plastic ball valve, is it normal to have that incoming flexible tubing be a little warm?
tank has been in home since we moved in. at least 8 yrs old. it is a 40 gallon that uses gas.
Thanks

Have you thought about possible calcium buildup in your hot water tank/pipes? I am helping a friend in Palm Springs CA (California not Canada) and we are going to pour a really huge pile of vinegar into the hot water tank (let it sit for a day) then open up the hot water taps to the kitchen (where we don't have hot water flowing very well), then going to let everything sit for another day. Remove the aerator from the kitchen faucet after letting the vinegar/water solution sit in the pipes for a day, and turn on the kitchen hot water tap. Once all the **** is drained out, you must of course drain out the vinegar/water solution from your hot water tank or you will smell like French Fries (in Canada we put vinegar on French Fries) when you shower for a few days.
If you don't understand what the basic chemistry of dissolving calcium via this method is all about, then please call a professional plumber. Hope this helps, and remember that Google is your friend (sometimes), but be careful...
