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.

SOURCE: Water is either hot or cold - no in between.

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?

SOURCE: no water coming from hot valve on faucets

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...

SOURCE: 2010 view winn- the hot water faucets, when wide

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.

SOURCE: I have a Rheem's Model # 81V-80D Water Heater. The

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.

Water pressure is high and over flow pipe is running


Have you measured the pressure or is it a faulty valve. Are the inlet and outlet valve open. There is a safety valve for thermal relief on top of the tank.

How to clear Major plumbing clogs


I am assuming that you are referring to a calcium or rust build up in the water heater.
If you are having this issue you will need to turn off the water to the heater. You will need a garden hose, access to a outside water soucre, cold water is fine.
Shut off the gas or power to the hot water heater before starting.
Now you will need to place the garden house on the drain fitting on the water heater, placing the end of the hose outside and lower than the drain valve. Open the valve and drain the heater, you will need to open a hot water faucet to help drain the heater. I don't suggest opening the TPR ( Temp Pressures relief )valve due to the fact that they sometimes leak or don't reseal after opening them.
Hopefully the drain valve is not clogged, you should hear and see water exiting the garden hose.
If you are not getting any water from the drain valve you are going to have a challenging task.
If no water is coming out, my recommendation is to get the required tools to remove the hot water line from the top or side or the heater, also a few towels to soak up water A bucket is helpfull also.
remove the hot water line, then you will have to use a small hose to siphon the water from the tank. Once the tank is empty you can then remove the drain valve and replace it.
once you have replaced the drain valve you should ensure that it's closed and use a Gallon of CLR. Poor this into the water heater through the hot water outlet where you removed the pipe from. Now make sure the faucets are closed and replace the hot water line. You can now turn the water back on to the water heater.
After a few minutes open a hot water faucet to let out any air until water flows out, than close the faucet.
Let the water heater set for a few hours, then drain the tank!
when the tank drains, close the drain valve again and refill the water heater. Once again open a a hot water faucet and let the air out till the water heater fills. Again let sit for a hour.
At this point open a hot water faucet at the farthest point from the heater and let the water run for 5 min. , than close it and move to the next closest faucet and repeat until all faucets have been opened and run for 5 minutes.
If you still have a slow flow in a faucet, you may need to repeat the CLR step.
I also suggest that you remove all faucet screens and clean them.
If you still have a clog than you are going to have to remove or replace a piece of water line in the house. The blockage may be hard to find but if you have access to most of the pipe or it's visable you may be able to hear the blockage with the water on. Otherwise this will result in using some water line taps and a pressure guage to find the blockage.

Our hot water will last for about 5- 10 minutes then turn luke warm. I have replaced both elements but problem remains . Do you hink it is the thermostat ? thanks chazz


If you have not done so already then turn thermostats up to 140 degrees. You may also try to drain and flush tank to clean out any mineral deposits that could be hurting your effiency. To do this shut off electrical power to heater then connect garden hose to drain valve on the bottom of tank. Run hose to floor drain or other safe area and open drain valve. If it drains good with the water on then let it flush for a couple of mins. then shut incoming water supply off. Let tank drain as far as it will. You may need to open a faucet on the hot side of nearby fixture to break vacumn.
Drain it completly then close drain valve and hot side of faucet.Turn water supply back on and let tank refill. Do this 2-3 times to get inside of tank as clean as possible. Hope this helps you and thanks. P.S. You may need to replace thermostat also.

Turned off the hot water to fix a leaking tap. now the tap has no hot or cold water and the hot water tank valve is leaking?


It sounds like two problems.
Problem 1) Clog inside faucet or clog inside pipes at faucet
Remove supply tubes leading to faucet and see if problem is inside pipes or inside faucet.
My bet is clog inside faucet.

If you have galvanized pipe that meets copper pipe, this can be trouble spot.

Problem 2) Water heater leak ... you say tank valve is leaking? Is that cold-water shut-off valve? Or tank drain valve? Or TP valve?

If cold water shut-off is leaking, then replace shut off.

If tank drain valve is leaking, then check if plastic valve is cracked. If drain valve is cracked, then replace with a brass valve from Home Depot. If plastic valve breaks off, then use hammer and screwdriver to gently chip out the broken plastic valve. New valve threads need teflon tape to seal pipe. If valve is just dripping, then put garden-hose cap over end of valve and screw down tight.

If TP valve is leaking, then replace with same temperature and pressure rating.
New TP valve threads need teflon tape to seal pipe.

Problem 3) If pressure is low all over house:
Buy pressure gauge at hardware store that screws onto hose connection.

Test pressure on outdoor spigot.
Open faucet and check if pressure drops. This says if problem is inside pipes that enter house.

Test pressure on water heater drain valve.
This says if pressure problem is before -or- after water heater.

If problem is before the water heater, then shut-off valve located on cold water line is suspect.
If problem is after water heater, it could be in hot water outflow pipe on top of water heater, or a nearby elbow.

Remove hot water line leading from water heater and check pressure. This says if problem is where hot water leaves tank.
Read articles above about clogs inside water lines.

We have a Reliance 501 Electric Water Heater. We get only very hot water in bathtub in one bathroom but not the other bathroom. Could the problem be the water heater?


No, the problem is not in the water heater. It could be the plumbing pipes were installed incorrectly.

A common problem with hot water is also found in the settings of anti-scald and pressure balance tub and/shower valves. You may only need to reset the temperature control on each faucet. Every faucet brand has a slightly different adjusting system. Hopefully you can find the faucet's brand name, and then visit their website to find the owner's instruction manual for your model.

A cross connection in the water piping system is rare, but it does happen from time to time. It would allow cold water to mix with the hot. You would need a plumber or leak detection company to locate every water pipe connection in and/or under your home to confirm and correct the issue.

Cant get my 50 gal rheem electric water heater to drain to change elements


There is 2 ways to do this.
The first way is to turn off the power. Turn off the incoming water (cold) to the heater. Go to a faucet close to the location. Turn off the cold water supply under the sink. Open the hot water side of the faucet. Allow any water to drain from the faucet. Make sure that the water coming out is not under pressure. You should be able to tell by how it come out. Easy, or forceful. Now go to the heater and open the bottom drain valve. The reason it does not drain very easy is because you have a vacuum. Similar to having a soda bottle full of water and turning it upside down. It will drain but it will "Glug" and drain slow. Opening the hot side of the faucet relieves the vacuum and it should drain o.k. When you are done with your repair, leave the hot side of the faucet open and turn on the incoming water to the heater on. Let it fill till you get a steady stream of water from the faucet. This "Burbs" all air out and ensures the tank is full prior to turning on the power. When you get the steady stream, turn off the faucet and restore power. In some cases, the heater may sweat because you are heating very cold water. This is normal and will only happen this one time.
Now if you want to know the second way, let me know. I've done it dozens of times with plenty of success and minimal mess.
Good Luck
