"look at the little thermometer"

Whoever posted that answer should be blocked from answering questions. A thermometer measures temperature, not pressure.

Most hardware stores will have water pressure gauges, they can be purchased for around $10.00 and may have garden hose threads or standard pipe threads of various sizes. You may have to adapt to attach to something near where you want to measure pressure. If you attach to a hose spigot, remember that pressure is lost from the moment it enters your home until it reaches an outlet. There is friction in piping and pressure loss due to elevation. Try to measure at something as close to where the water comes in to the home, not at a line far away where it is exiting.

When testing the pressure one must do the following1- With a gauge you test the pressure with no flow to give the incoming available pressure

2- Open a tap and watch for a pressure drop, which can be quite severe with ferrous metal piping

3- Then you take the pressure and times it by 2.31 that will give you the height the pressure will elevate the water

For example you have 40 PSI will elevate the water to 92.4 ft to prove it you take 94.4 feet and times that by .433

The friction losses are not that much of a concern if your not working on a high rise building or long developed lenght of piping and fittings non ferrous metal piping or plastic offer the least amount of friction losses

What is a concern is the velocity which if unchecked can cause piping erosion and hydraulic shock (water hammer)

A hydronic boiler gauge is a great tool as it is a tri-indicator giving static pressure , and actual operating pressure as hot water gets heated it expands increasing the pressure thus incoming pressure can be raised considerable when heated

What does it mean when the water pressure in your house is low?

If you are on a well it means you have a problem in the pressure tank. On city water means pressure in general is down, or your PRV is failing.


What should water pressure be in a house?

Normally between 40 and 80 psi, but mine runs about 90....


You woke up this morning and you had no water coming through any faucets in the house so you checked the pressure tank and it showed zero pounds on the gauge What do you do?

Increase the pressure to 40 PSI


What would cause no water flow at all throughout the house and could it be the pressure tank?

== == Two possible problems............... The main shut off valve in the house is closed from the in-coming city water supply line, or the city supply line is shut off at the street .


When you want to a set up a water tank why do you put it higher than the house?

Think of it as water flowing down a hill, but instead of on the ground it is in a pipe. For a typical "Petticoat Junction" type rain-water reservoir that will supply the home with running water, it is the difference in height between the faucet and tank that provides the water pressure to push the water through the pipes. The higher the tank, the greater the pressure at the faucet-- which means higher flow. If the tank was not higher than the house, nothing would come out of the faucet. A city water supply supposed to be around 60psi but can vary greatly depending on the terrain. Since most water is gravity fed from elevated tanks, a home at the bottom of a hill will have higher water pressure than one at the top of a hill. Cities with big ranges in elevation have pumps to boost pressure at higher areas and regulators to reduce pressure in lower ones. The elevated tanks are closed at the top and do not collect rain water. Water is pumped up to the tank overnight while people are using the least amount. During the day, the full tank supplies all the water the city needs. High-rise buildings are fed with the same water supply as the rest of the city, but have booster pumps every so many floors to maintain a reasonably constant pressure over the full height of the building.
