Re: When hot water is on & toilet flushed the temp drops
Check strainers and screens into the sink, at the spout and into the hot water heater. Sediment buildup could be limiting the flow which woul make the system more susceptible to pressure drop when the toilet is flushed.

Water heater 14 years old, probably has never been flushed, Flush recommended at least every 6 months, Build up inside tank may be to late to flush, but you can try or replace heater. press the helpful button
The water heater has nothing to do with it. You need a shower control valve that won't let the water pressure change when the toilet is flushed. Moen makes just such a valve called a pressure balancing valve. Moen L82683 Positemp Tub/Shower Valve. http://www.moen.com
I am not sure what you are asking, But i am going to assume that you want to know about changing the Temp on the heater for inside the house. If the floor heat was installed properly than it should have a temperture manifold or adjustable thermostat for seperate heating. You need to find the thermostat or manifold for the garage heat and set it at what ever temp you want the garage to stay at. Then you can change the A B C knob to a higher setting A is cold B is warm ac is hot. So Increase your temp setting on the heater and this will increase your house water temp for hotter showers and faucet temps. However, they recommend not setting the temp above 120 degrees to prevent severe burns. If you have a newer home increasing the Hot water heater temp setting may not change the temp at the shower or faucets if you have scald guard faucets installed in the house. This will require adjusting the scald guard valves on each faucet. I recommend using a candy thermometer or digital thermometer to check the faucet and shower Temp prior to using them and make sure that you inform everyone in the house after you change the temp so that no one gets scalded. I hope this answers you question, feel free to contact me if you need more help! DR Wilkins
Ok that sounds more life a faucet that is bad. In today world, the newer (20 years and less) they have pressure balance faucets. Have the faucet serviced. NOW lets look at an other area check out your home to see if you have a cross connection. A cross connetion is a place where hot and clod water meet. I know that everywhere but the toilet!
Yes thats true. But we buy all kinds of things that we attach to a fauects or tub spouts. Lets say you attached a hose to the sink in the garage to wash the dog with warm water. if you turned the water off at the handle of the hose and you left the water on at the faucet. BINGO
the hot and cold water mix and then up and down water temp while taking a shower.
So start looking first before spending any money. if ANYTHING is attached to any faucet take it OFF and then take a shower.
well it is time to get the the two way valves to both side, I would use only a product the noritz says to use.
Now if you cant get it you can get other products that break up lime and scale from you local store that sells plumbing product. I you can see I dont list a store or a product I am here to help you repair your heater, Not have you buy from one store or an other.
With that being said you can vinegar but dont use acid. If yuo "burn" the inside of the heat exhanger you jusy might be buying a new unit. also Please flush out the system with cold water for at least 10 mins. with the 3 way valves that should be very easy to do.
You also might have a lime build uo in the faucet also which will affect how they work. You may want to replaced and cleanout the cartridge and see if you have a lime build up. If that is the case you might want to think about a low priced water filter or softener.
Hope this helps you out and please dont for get to rate me, and Be safe
when was the last time that you have "opened the flush valve (faucet) at the bottom of the tank to clear out the sediment? if it has been more then 4 years then you will need to do this depending where you are located this should be done once a year just to keep the tank clean. attach your garden hose to the valve and run it over to the sink open the valve for a few moments to clear out the tanks bottom (HOT WATER ALERT!) after doing this and if you have seen dirt come out then your tank should be clear. check to see what the tempature is every 1/4 inch is 10-30* increase hope this helps
it is because the tub has a temp control valve in it so if you were to put more cold with the hot it will last longer but still won't be all the way hot,, now a days people are suing the manifacture because they are getting burned form the hot water so they put these saftey temp controls in place of the old style 2 or 3 handle faucets,, there fo no more real hot water nothing you can do outside of change to the othere type of faucet 2 or 3 handle tub shower diverter,, that why the water is hot in the sink but not the tub.....
I had a customer a few weeks ago that had the same problem. When the water heater was installed they crossed the supply lines. They had the inlet as the outlet. Esentially, the water heater was plumbed in backwards. Also there could be a miss piping somewhere in the house but it would probably be near impossible to find it right now without tearing up foundations. Also check that the faucet is not plumbed backwards as well. Especially if this is a single handle faucet that you are referring to.
