So, a pressure tank is used as a back up system for when the water pump is on the off cycle; why does the pump have an off cycle? Is it just to give the pump a break so it does not wear out? However it all works, I'm glad that there are systems to provide water pressure for our sinks and showers! http://www.bwsfabrication.com

Pressure tanks do just that in a water system. They create pressure for water to flow when the water pump is on the off cycle. A manifold is plumbed into the tank from the main line coming from the well. The main water line continues to the house plumbing from the manifold. So it's line from pump to manifold - to tank, and from manifold to main into house. The manifold also has tappings for the pressure gauge and the pressure switch. The pressure tank creates water pressure. The water does not flow through the tank. Pressure tanks also have to be 'tuned' or adjusted to the low end pressure set by the pressure switch. Actually the tank pressure needs to be set 2psi below the low end pressure. Most residential water systems are set to operate between 20 -40, or 30-50 psi, which is set by the pressure switch, which in turn , turns the water pump on and off. So if a system operates between 20 and 40 psi, the pre-charged pressure of the tank should be 18 psi. Pre-charged means the tank is drained of water with the water pump OFF. The tank pressure is then checked adjusted by way of the air valve on top of the tank ( A tire gauge works). Pressure tank mainfolds are a common plumbing part.

How to change out copper piping from release valve


If the release valve referred to is the pressure release valve, then a water leak out the attached vent pipe is an indication that the valve is failing. To change the valve, the water must be allowed to cool (turn off AC power or gas) and the water level inside the tank must be lowered (drained) to below the level of the pressure relief valve. Once this is accomplished the vent pipe is unscrewed from the relief valve and the pressure relief valve is unscrewed from the water tank. A new pressure relief valve with a sealant on the threads, is then screwed and tightened into place with the outlet port facing downward. The vent pipe is attached to the new valve and the tank refilled with water. A hot water facet must be opened to allow air to exit while filling. Upon becoming full (water will begin to flow from facet), turn off the facet and restore AC power or gas, therefore allowing the water heater to heat up. When the first hot water is utilized there may be some air expelled from the facet.

Whyexpansion tank istalled in fire fighting system how its works and what is the link of pressure expansion tank with pressure switch


Hello,

Expansion tanks are used in wet or dry fire suppressions as well as other hydronic (heating/cooling) systems to compensate for temperature and pressure differentials (expansion/contraction) in the piping system and to maintain a constant pressure in the system. As liquids heat and cool they will expand or contract. The pressure switch you describe is usually connected to an air compressor that will cycle on and off as needed to maintain the system pressure.

The expansion tank should never be completely filled because liquids are not compressible and can cause excessive system pressurization and subsequent malfunctions or rupture of components (water hammer) or pump seals. Some expansion are equipped with "site glasses" so the water level in the expansion tank can be observed and monitored.

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.

Water heater should be set in a drip pan.
Otherwise, put 1 gallon bucket under TP release pipe to catch water.
http://waterheatertimer.org/Water-at-bottom-of-water-heater.html#drip-pan

When you say relief valve, I assum you are talking about brass valve located on top of tank or near top of tank. This is TP valve and a pipe connects to this valve and runs down to within 6" of bottom of tank. TP valve has a small lever on it.
If you are talking about tank drain valve located at bottom of tank, then add a comment.
Following information is for TP valve.

Dripping TP valve can be caused by 3 different thing:

1) Obstruction inside TP valve. Open TP valve for a moment to flush away particles and slowly lower lever back down. See if water stops dripping, if not, then replace TP valve

2) Defective TP valve: replace TP valve. Turn off electricity to water heater. Let heater cool for several hours so you do not get scalded. Close shut off valve located above tank on cold side. Open tub spout to relieve pressure, open tank drain or open TP valve and empty water below TP valve level. If TP is located on top of tank, not much water has to be drained. Tank is under press when hot, so be careful. Put teflon tape on new valve and install with big pipe wrench by turning clockwise until TP valve is very tight.

3) Overheating tank. TP valve is temperature-pressure valve. If tank water is over 150 degrees, the TP valve starts drizzling hot water to relieve tank pressure.
Lower tank pressure two different ways:
a) turn down thermostat

b) install expansion tank on incoming cold water line

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

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.

How does rhe hot and cold water hook up on a 71-40d which is which top and bottom


Tanks are marked with Hot and Cold.
1) If water connections are on top of tank, look for red marking or word HOT that shows where hot water pipe connects. Look for blue marking or word COLD that shows cold water connection.
2) If water connections are on side of tank, cold water connects to bottom one, and hot connects to top.

3) If hot and cold are reversed, the tank will not work.
Pipes on top of tank: cold water enters tank and is sent to bottom of tank in a long tube called the dip tube. This means the cold is on the bottom since hot water rises to the top. The hot water exits top of tank.
Pipes on side of tank: You want cold water to enter bottom, so hot water naturally rises to the top outlet.

When I turn on the tap, the water does not come right away


Sounds like the pressure tank isn't working right. The pressure tank should have air in it that is compressed by the water, so that when you open the tap, the air pressure should immediately begin pushing the water. Water is virtually incompressible, so you need that air to give you some volume to be compressed. After the air pushes the water for a moment, the pressure drops enough so that the pump kicks in to maintain and restore that pressure. If you don't have such a tank, that's the problem. If you do have such a tank, then it may be full of water and you will have to find a way to fill it with air. Or, perhaps the tank is not piped correctly. I hope you found this helpful. Good luck.

Culligan RO sstem has recently stopped producing more that 6 oz


This might be a possible tank pressure issue. This could also be a clogged filter. I would first check the tank pressure by using the following steps

Necessary Supplies:
1) Tire Gauge marked in 5psi increments (ie 5, 10, 15, 20psi, etc.)
2) Bicycle tire pump for standard type bike tire valve

To recharge RO System Tank:

1) Close cold water feed valve (valve located at some point along the cold water line from street plumbing).*
2) Leaving RO tank valve on, turn tank on side & locate valve stem on bottom side.
3) Remove stem cap.
4) Drain all water out of tank through open RO faucet into sink. (Continue to leave RO faucet open throughout procedure)
5) If current tank pressure is insufficient to empty tank, apply tire pump to valve stem and pump 10 – 15 times. Exit flow will increase and then gradually decrease as pressure equalizes. Do not overcharge internal bladder of tank during this procedure.
6) Repeat step #4 until tank is completely empty. (Tank is empty when additional pumping produces no more water)
7) At this point, adjust EMPTY tank to exactly 7psi. (Gauge reading midway between 5 & 10psi is sufficient)
8) Turn off RO faucet.
9) Replace cap on valve stem and reposition tank in upright position.
10) Open cold water feed valve.*
11) System water is useable immediately, however, tank will take 3-4 hrs to completely refill.
