Why is your hot water pressure low but your cold water pressure is fine after installing new water hetar?
Your cold water comes directly from the main line without hitting resistance. Your hot water travels through your water heater which may decrease the pressure. Is this a new problem or has it always been like this? If it is a new problem you may be getting build-up in the lines near the water heater or even in the water heater.
Hot water also tends to have more deposits in the piping. If you have galvanized piping, you could have a lot of corrosion in the pipes. Hot water heaters do get scaling build up. It might be worth having it checked out, a broken hot water heater can be pretty messy!
The answer may differ according to where you live. In the UK the cold water comes from the main which is kept at a moderately high pressure, for example by a water tower. Any leaks are then "outwards" with less chance of inward contamination. The hot water in a house is generally provided from a tank in the house attic, which auto-refills when water is drawn off, stoppnig when full by a floating arm which cuts off the supply to it. This tank at relatively low height provides lower pressure water to the house boiler.
The supply of water needed by toilet as it refills is greater than what shower supply is, not actually a lack of pressure so much as a lack of water volume. Pipe sizing needs to be properly sized so this "pressure drop" won't occur. Installing a new shower pressure balancing valve should help with this problem if running new cold water lines of proper size isn't possible or practical.
Why does my cold water pipe make loud ringing noise only when the weather is cold and when we run the hot tap?
Because by flushing the toilet while using the shower, you have removed some of the water pressure on the cold side. This decreases the amount of water flowing to the shower head. Therefore changing the mix more toward the hot side. Answer this is also due to incorrect pipe size installation of cold piping. increasing the pipe sizing will solve the problem Installing a "pressure balanced" shower valve will fix the problem as well.
When installing hot and cold water to a washing machine how can you tell which is hot water and which is cold water connections?
The pressure balance valve compensates for changes in water pressure. It has a piston inside that reacts to relative changes in either hot or cold water pressure to maintain balanced pressure. As water pressure drops on one supply line, the valve reduces the pressure on the other supply line to match.
If someone were to flush a toilet, the water pressure could drop accordingly. If you lost all water pressure, chances are that your main water line coming into the home has a huge leak or not enough pressure. The hot water tank is pressurized by the cold water pressure coming into the house. If there is no water flowing from the water meter into the home, you won't have any hot water either.
Is there a problem with the hot water tank if there is no hot water pressure throughout the house but the cold water pressure is fine?
No it does not. The heating of water causes the molecules of hydrogen and oxygen to become 'excited' and 'vibrate' at a higher rate than cold water. The hotter the water gets, the more of a reaction it gives off. The chemicals begin to separate and cause steam. This action is the direct cause of pressure building in a closed container. In any open containers the difference in the pressure is very small and then…
I just had a home inspected, and the inspector measured the static water pressure at 115 psi. He noted that this pressure shouldn't be above 80 psi and recommended installing a pressure reducing or regulating valve to get the pressure down to 80 psi. He warned that too much pressure stresses pipes, fittings, and valves and can cause any of these to fail. Most solenoid valves on a washing machine or dish washer would not…
The water pressure when one turns on the hot water is lacking because the water is coming from one's water heater, which is at the same level as the faucet, whereas the pressure from the cold valve is coming directly from one's town's water tower, which is at a much greater elevation. Also, the water heater tank is only a few feet high, whereas the water holding cell in a water tower is several feet…
Hot water is lighter then cold water so it would stay up on top of cold water till both waters naturalize to the same temp. a good example is a water heater and (if its not to old) open your drain at the bottom of the water heater and if your dip tube is still good you should always get cold water out of it even if the water heater is on and your water…
