How many valves on by-pass, or what style by-pass have you got on there? Remember water has to go in bottom (cold) and then out top (hot) . No valve in between should be open. Valves going direct in to cold, and out hot need to be open.

How can I increase the hot water pressure in my home?


Cold water pressure is what give you your hot water pressure so they should be equal but if you have a restriction on the hot side such as a valve not opening on the hot side or not opening all the way then you will have less pressure or the pipe work on the hot side is not proper. Hard to say but check the valve on top of the hot water heater

I have very low hot water pressure in may home....cold water pressure is ok....


You have clog in hot water line or inside water heater.
Use Brady BTG100 pressure gauge to assist.
http://www.ronshomeandhardware.com/BTG-100-100-PSI-Water-Pressure-Gauge-p/405357.htm

Put gauge on outdoor spigot and then turn on hot water to get baseline.
Put gauge on water heater drain, and then turn on hot water. If pressure stays high, then clog is in hot water nipple or inside pipes after water heater.
If pressure drops, then clog is in cold water nipple, shut off valve above tank, or somewhere in line between main cold water and water heater.
Water heater nipples, shut off to water heater, and elbows are good suspect.
Any galvanized and copper connection is good suspect.

I am losing water pressure, but only on the hot side. Cold pressure is fine, as you add hot the pressure fades, the hotter the less pressure. This is at all points in the house. The water heater was...


You have a clog in the hot water line.
If problem is at one faucet, then remove aerator and clean, then disassemble lines underneath sink.

If problem is at every faucet, then that moves search close to water heater.
Look at hot water line that exits water heater and trace that line to first Tee.
Look at cold water line that enters water heater and trace that line to Tee.
Clog is located between those 2 Tees.

Buy pressure tester that connects to hose thread.
geno_3245_251.jpg
Connect pressure gauge to hot water heater drain valve.
Then conduct same test you did at faucet.
See if pressure drops at tank.

If pressure drops, then clog is on cold side of tank, and probably hot side too.
If pressure does not drop, then clog is on hot side of tank.

Suspect 1 is any place two different metals join. For example galvanized pipe and copper.
Suspect 2 is supply pipes that exit top of tank. Take apart and look inside pipes for corrosion and sediment lining pipe walls.
Suspect 3 is elbow. Disassemble pipes and look for sediment and flakes of rust.
Suspect 4 is all suspects above, each having sediment and corrosion.

I have a hotpoint hot water heater it's about 6 years old. When I turn the hot water on it runs very slowly the water pressure is very low and it's like this throughout the house how do I fix this problem...


You have clog in the water line.
Since all hot water pipes are involved, clog is probably near water heater.

Buy pressure gauge at hardware store that threads onto hose connection.
Brady BTG 100 at Amazon
Picture of gauge

Check outdoor pressure for baseline pressure in your home.
Turn off electricity to hot water heater for an hour or two so there is not scalding water.
Open drain valve on water heater to see if water heater is clogged with sediment.
http://waterheatertimer.org/Water-heater-will-not-drain.html

Put pressure gauge on drain valve and compare with outside pressure.
Open hot water spigot on bathtub and see if tank pressure drops ... if tank pressure drops significantly with bathtub spigot on, then clog is on incoming cold water before tank, and could be on outgoing hot water pipes too.
If tank pressure stays about the same, then clog is on outgoing hot water pipes.

Clog can be sediment caught in cold water shut off valve located above tank. Open and close valve and test pressure again. Take apart incoming cold water pipes above tank and check for sediment. Replace valve. Look at condition of cold water nipple on top of tank.

Sediment caught at hot water elbow near tank.
Sediment can fill up old pipes. Take apart hot water pipes above water heater and see condition.
Look at condition of hot water nipple on top of tank.
You may have to take apart pipes up to first or second elbow.

Pipes can decay at joint where copper pipe connects to galvanized pipe. Check for copper to galvanized connections on cold or hot pipes and replace section of galvanized pipe. Copper pipe will probably be good, the galvanized pipe will deteriorate. Replace copper-to-galvanized joint with 3/4" non-conducting union from hardware store

No water pressure in bath tub after turning off hot water heater


It could be back flowing into the hot water heater tank which is not full because of the leak. Even though the valve is closed on the cold water entry side, there is probably no valve on the exit side. That is how it is returning to the tank.

We have a customer that has a 751od who says at times thier water gets cold for a few seconds. No error codes on the remote. They claim it does it at different fixtures. Everything checks out from water...


A few things you should check:

1. Cross Connections - this occurs when cold water leaks into the hot water system through a fixture. In order to check for a cross connection: 1) turn off the cold water to the tankless 2) open up hot water fixtures in the home. The water should shut off at all hot water fixtures; if there is a continuous flow of cold water, then you have a cross connection. The most common place to find a cross connection is on old shower cartridges.

2. Ask the customer to check to see if the burner indicator is continuously lit during operation.

3. When the water goes cold at one fixture, try another near by fixture to confirm it is also cold there. If its hot at one fixture but not the other, then you have some issue with you plumbing. Tankless heaters can't pick and choose which fixtures to deliver hot water to.

4. Tankless water heaters all have a minimum flow rate that must be maintained in order to continually fire (.5 gpm for Noritz). Ensure their hot water fixtures flow at least this amount, or that the customer isn't mixing too little hot water at their fixture.

5. If they see the cold spurt during initial firing, they may be experiencing a cold water sandwich. When the heater moves from a standing state to a firing state it takes a short period to ignite and heat water. During this time it will be passing cold water through the system. Usually this cold water mixes with hot water in the line as it travels through the plumbing system, but if their fixture is very close to the heater, there won't be enough time to mix.

6. If debris has gotten into the flow sensor, this can prevent the unit from registering flow and cause intermittent firing.

Tp valve opening and dumping water


Certain water heaters can only handle so much pressure from the main line. There is a pressure controller between your water meter and you house, it's called a pressure regulator. You need to call a plumber to check and see if it needs to be adjusted or even replaced.
