Look on the main supply pipe near your water meter for a conical valve that has a bolt sticking out of the cone. To raise pressure, turn the bolt clockwise after loosening its locknut.

A water pressure regulator, if you have one, is usually located where the main water line comes into the house and after the main shut off valve.

If you are only experiencing inconsistent water pressure in one fixture, try cleaning the fixture. Start by removing all debris, then clean thoroughly. If that doesn’t work, you may need to replace the entire fixture.

The screw is your adjuster and it can be maneuvered only by loosening the locknut. As you tighten the screw, the water pressure will become greater and as you loosen it, the water pressure will lessen, so turn the screw clockwise to increase the pressure, or turn it counterclockwise to decrease the pressure.

1. Attach the water hose to the outdoor water spigot. Turn on the water spigot so water courses through the attached water hose.
2. Raise the end of the garden hose as high as possible. Continue raising it until the water stops coming out.
3. Measure that elevation from the water faucet.
4. Divide that elevation by 2.31.

Normal psi for a home pipe system is between 30 and 80 psi. While you don’t want the psi to be too low, it violates code to be above 80. Instead, you should aim for a psi that’s between 60 and 70.

If your sinks and shower have irregular water pressure, or the pressure seems very strong at all times, it may mean that the water pressure coming into your house is too high. What’s more, high water pressure can put extra stress on your pipes and can even lead to leaks.

High-pressure water can cause serious problems like pinhole leaks in your plumbing and severely shorten the life of your water heater, dishwasher, boiler system, and washing machine and increase your water bills.

Pressure is higher at night, when fewer people are using water. If your pressure reads over 80 PSI, you need to take action to protect your plumbing system.

Typical water pressure runs from 40-170 psi. The heaviest demand for water is Monday, Wednesday, and Friday, when most customers are in the habit of watering.

Basically, you want every faucet that has a water connection, including your washer and dishwasher, to be turned on. Start with the faucet that’s closest to the shutoff valve and work your way to the farthest faucet. Open each hot and cold faucet about halfway to let the air run out.

Is My Water Pressure Too High? The signs are well known—banging pipes, running toilets, dripping faucets, and running out of hot water very quickly all indicate that the pressure is too high in your system. If yours measures over 80 PSI on the gauge, it is definitely time to lower the pressure.

Calculate the GPM Flow Rate Multiply the measured quantity of water by 6 to calculate the flow rate in gallons per minute (GPM). In our example, 1/2 gallon collected in 10 seconds multiplied by 6 (to equal one minute) equals 3 gallons. Therefore, the flow rate is 3 GPM.

If you simply need to figure out the mL per hour to infuse, take the total volume in mL, divided by the total time in hours, to equal the mL per hour. For example, if you have 1000 mL NS to infuse over 8 hours, take 1000 divided by 8, to equal 125 mL/hr. To calculate the drops per minute, the drop factor is needed.

Flow Rate Q = Volume / Time

1. Flow Rate Q = flow rate in ft3 / second or cubic feet per second.
2. Area A = cross sectional area flow in sq.
3. V = velocity in ft/sec – for systems where V varies use the average fluid velocity in the pipe either in feet per second or in meters per second.

In other words, how long should it take to move the entire contents of your swimming pool through the filter. Divide the pool gallonage by the turnover rate to determine the minimum flow rate per hour. Divide that number by 60 to determine the minimum flow rate per minute.

8 hours

So to answer the question, yes, you can replace your 1hp pool pump with a 1.5hp pool pump, but only if your situation calls for it. This will provide the flow that is needed to circulate your pool water properly and save you from high electricity bills at the same time.

Determine how many gallons you need to pump per hour to clean all the water in your pool in eight hours. Divide the gallons of water your pool holds (answer from step 1) by eight. Using the example number of gallons previously given, this equation would look as follows: 24,000 gallons ÷ 8 hours = 3,000.

about 20 GPM

According to the chart for 50 Feet of Head (closest to 47′), we need a pump between 3/4 HP (31 GPM) and 1 HP (50 GPM). Since we always go for the higher GPM, we would select the 1 HP pump.

There is a very persistent myth in the pool world that the higher the horsepower, the better. As a result, it is probably safe to say that the majority of pools have oversized pumps. Too large of a pump can cause poor filter performance and even damage it, if the filter is not also oversized accordingly.

Maintenance. The main advantage to over-sizing a filter is the reduction of cleaning throughout the pool season. With the larger filter there is more media in which the dirt can disperse, allowing water to flow freely. The larger the cartridge, the more dirt it can trap.

There is no need to run a pool pump continuously for 24 hours a day, with a few exceptions. It is normally recommended that your pool pump should run long enough to pump the entire volume of water in a pool each day. In practice, this generally means around 8 hour each day.
