If you have an instantaneous hot water heater, and your faucet doesn't flow enough water it won't turn on the water heater. Thus requiring another faucet to be turned on.

What causes low water pressure in just one set of faucets when all other faucets on the house have good pressure?

You have to undo the aerator at the end of the faucet and clean the screen or plastic water saver out. It will be plugged with sand or sediment.


Why is cold water being siphoned into hot water lines?

It may be caused by your faucets needing replacement cartridges, if your faucets are single valve type. Note: I learned of this several years ago working with the Moen technicians (they willingly helped diagnose the problem.) This may seem counter-intuitive but when a house is built the installers will choose one manufacturer for faucets, although many different styles, within the house. If they install a single handle type the seals on the faucet cartridges start to deteriorate and begin to "bleed" the hot water into the cold water lines and visa-versa. If you replace only one of the cartridges the problem will migrate to another faucet, within a short time. So I would suggest replacing all the cartridges at one time. Since I was in the trade buss. Moen actually paid for the replacement cartridges if I agreed to send all the old ones for study. (I doubt that Moen will do it for you.)


How do you fix low water pressure due to calcium build up?

If you notice reduced pressure in one of your faucets and not other faucets, and notice that the flow is reduced in both the hot and cold sides of the same faucets then it is probably your aerator. If it is only on one side of your faucet (hot or cold side) then it is probably a mineral buildup in the valve of the faucet (you can clean that side or replace the valves components.) You can also try to loosen the mineral deposits by... first removing the aerator then turn off the supply line valve ( the valve under the sink, several times) to try and dislodge the mineral deposit; if you leave the drain stopper closed and place a dark colored wash rage in the sink, you may notice the deposits flowing through the faucet. While you have the aerator removed clean that or replace it, they are cheap.) If all this fails then you will probably have to replace the valve under the sink.


What needs to be repaired when you have hot water getting into the cold water faucets of your house and is this caused by a failed shower mixing valve or just a failed gasket in the shower valve?

It depends on the valve, who makes it and what model is it? you have a cross connection in the water system ( I don't think it is the value, most of the time it is on your washing machine hot and cold water valve. Go to a faucet away from the machine and turn on the water. Then go listen at the machine you should hear water going through the hot and cold water valve of the machine, it is where your water hoses connect.) hope this helps If it is a new house and has always done it. It might be that they connected the hot and cold water together somewhere in the wall. You would need a plumber to find it. It is not easy to find though. Would most likely be having to open up a lot of holes in wall to find. Sometimes you will find it by trying fixtures one at a time. The one that gets hotter quicker is where it was tied in with the cold. Open up wall there. Then turn on water at the fixture and feel the pipes and the one that is hotest that is tied to cold would be the one you would have to change. You would have to take pipes apart and connect it back to the hot side. So you would be taking hot and cold apart so i would get plumber to do this. At least if you could find out where they were connected would save you a lot of money.


What would cause sudden water pressure drop?

Some causes for a sudden water pressure drop: 1) A big leak on the main supply line. 2) one or more faucets or shower heads opened on the same water line. 3) A utility water pump failure.

If the hot water tank is not connected why is water coming out of all the faucets on the hot side?

There is a hot/cold cross connection at one or more of the faucets at you house. make sure all faucets are shut off both hot and cold. If it still occurs more than likely you have a Moen faucet somewhere (most likely).

Why is hot water taps not working in bathroom when it's working in kitchen?

The most likely reason is that the hot water valve is turned off in the bathrooms. Look under the bathroom sink. There should be two valves - the one on the right controls the flow of cold water and the one on the left controls the flow of hot water. Turn the hot water valve counter-clockwise to open.
