Question about Water Heaters
Have only one incoming water valve, need to block off one faucet connector on lever type faucet
You can do this one of two ways:
Get an appropriate sized plumbing plug for the unused line. This will mean you only get water from the cold side and no flow from the other, or...
Get an appropriate "T" fitting and connect both lines from the faucet together, then run your supply line to the "T". This will mean you get the same pressure regardless of the cold/hot orientation of the handle.
I have used the second solution for deep sinks where hot water is not readily available.

I found a way to get warm water in the shower, but I'm not sure it qualifies as a solution. After trying everything else I thought that maybe when I was feathering the faucet in the shower toward the cold side so I would get warm water that at a certain point it blocked the flow on the hot water side enough so that the sensor in the hot water heater sensed there was no demand in the line and it shut the water heater off. To test this, I went to the kitchen and turned the kitchen sink faucet all the way to the hot side and then turned it on so that I got a small flow of water. I waited for the water to get hot to be sure the hot water heater was working. Once it was hot, I left it running to keep demand in the line and then I went to the shower and turned the faucet on. When the water got hot I started feathering the control towards the cold side and soon I had warm water. So I think I'm right in that the sensor in the hot water heater was shutting the water heater off when the demand in the shower was lowered to a certain point when I was trying to adjust the water temp in the shower.
So now I can get warm water, but it means I have to leave the hot water running at another fixture in the house to create a false demand in the system so the hot water heater doesn't shut down. Is there a way to adjust the senor in the hot water heater so that it will stay on when I'm using the shower only, so I don't have to waste water by running another faucet when I want to take a shower?

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...

Double check that washers inside fittings attached to back of tank, are not wedged or pinched in there restricting flow. Drain tank, relieve water pressure prior, obviously. The other thing is to check that the by-pass is allowing good flow in to tank when in normal operation mode. Have seen those only go half way inside valve, but lever is at wide open setting. If all that checks out, try removing the check valve on tank, and replace it with a 1/2" galvanized pipe nipple, ( or certified plastic/nylon fitting same size) and reconnect water line direct to that, without a check valve. That should do it if nothing else was wrong. Now you have a choice, either change it or leave it out if everything seems ok, but double check that hot water isn't siphoning back to another utility such as toilet if you leave it out and toilet is close. Feeling that cold line (inlet) when water is hot should tell you. I've seen the check valve in both locations, hot (at top of tank) and cold (at bottom of tank -inlet) Not 100% sure why, right from factory that way, but I say, put it on bottom fitting if required at all. Let me know how you make out.

Not uncommon for calcium etc to build up in water heater, from water pipes, and water itself. (hard water) Simply removing aerator and screen etc and cleaning it will usually take care of it, but if too dirty, soaking in C.L.R. will help, or for a few bucks just replace it from hardware store. Just make sure you take old one with you to match it up, as there are many that look the same but aren't. You may also help the situation by shutting off power to water heater, allow it to cool, and drain it out, which should remove some of the calcium laying in bottom of water heater. I've had some with such a build up over the years, that I removed the element to look inside and it was right up to the element. Used a shop vac, with piece of 1/2" plastic line taped to it and sucked out as much as I could. Took about 1/2 hr, but got most of it out of there.
