Pump Size How to Calculate
Pump Size Calculation: Gauging the correct size for your water garden pump will ensure your pond receives the proper water circulation. Unless the pump you buy is already configured with a built-in fountain head, you'll need to calculate how much a pump can handle before you choose a certain size or model. A good rule of thumb is that pumps should be able to pump out about half the pond volume every hour. So a pump that moves 500 gallons per hour would be appropriate for a 1,000 gallon pond. In order to determine the size pump you'll need, you must calculate several key measurements.

The pressure keeps creeping up to 30-35 psi. what
If you are certain the gauge is accurate (does it return to zero when the system is off?) and the system has worked well in years past it means your sand bed has deteriorated to the point that backwashing no longer removes enough debris and/or the sand is worn enough as to become to compacted in the tank. Either way it means it is time to remove at least the top several inches of sand and replace it with one 50# bag or better yet, remove all the old sand and refill the tank with new sand in the amount indicated on the label under media...it will be in multiples of 50#.

How do i calculate pump size how do select pump
Thank you for posting your question here on Fixya.com.
The short answer is based on amount of fluid needed at the delivery point(s) and at what pressure that fluid needs to be at those points. If it is a pool pump the answer changes slightly since a pool is a closed loop system and you are more concerned with the turnover rate of the water in order to keep it clean. Is there a specific application you need help with? If so please add a comment to this post and I'll see what I can do to assist.

How do you convert a 1997 760 Yamaha Waverunner
There is nothing to convert. After running it in salt water, you need to flush the engine out either on a garden hose or by running it in a fresh water lake or river prior to storing. Salt water is very corrosive and you need to flush your engine just as soon as possible after removing it from salt water. DO NOT let it sit overnight, it will start corroding internally and doing damage.

Where dothe hoses go
Suction from the pool goes into the front of the pump housing ... Discharge from the pump goes to the filter. If multi-port, there is a suction and a discharge port identified. If it is push/pull, Top port goes to waste, center is water in, bottom is water return to the pool.
Pool water is suppose to go into the top of the filter and out the bottom for return to the pool.
When manipulating the valfe (multi-port or push pull), ASSURE the pump is OFF! If multi-port valve, only turn the handle clock-wise.

HOW DO I CALCULATE THE HEAD OF A SWIMMING POOL
The pump is rated to produce (x) amount of GPM. (gallons per minute) If your wondering about the pressure the pump will produce, It depends on a lot of variables, like at what point in the system output you measure and how far from the pump (friction loss). The pump name plate should show some data, start there. Go online and get the data for that specific pump. Check with Mfg of pump.

No green comes out in backwash
Alge will quit often go through filter so first you need to kill the alge by super chlornateing the pool. You can take a water sampel to your pool store and give them the size of your pool, they can test your water, for nothing in most cases and recomend what you will need for this. Then you can start cleaning the mess up as the dead alge will turn to dirt. This dirt will be very fine and may go through your filter also so a cup full of D.E. in your skimmer after backwashing will usually coat the top of your sand and catch much finer dust and dirt. Do this as you clean the pool and backwash 1-2 times daily till clean. Follow all directions given to you at store to kill the alge first, this is very importiant.

In-g pool loss of pressure and bubbles from return line any ideas
If you notice bubbles in the water returning into the pool from the eyeball/discharge, or water in the strainer basket is visibly swirling (bubbles visible) odds are you need you replace the o-ring on the lid of the strainer basket in the front of the pump. This basket may also be clogged with debris, which also effect pressure. Could also be a cracked or warped strainer lid. Should be easy to see when you remove to check o-ring. Once you remove the strainer o-ring make sure you lube it with a good silcone based lube.

With filter set on
Your question was posted under "Pond and Water Garden Pumps", but I assume you are really asking about a swimming pool filter. Unscrew the control valve from the valve body and check the condition of the O-ring. If it is nicked, torn, or worn allowing water to flow past the valve, buy a replacement at your local hardware store or swimming pool supply. Pop the old one off, and put the new one in the track where the old one was. If it doesn't want to stretch to fit, put the new seal in HOT water for a few minutes and try again. Lubricating the O-ring with some Vaseline or other brand petroleum jelly will make operating the valve easier and cut down on wear of the new seal.

Hello,\r\n I'm running a 3 year old 1.0 hp
Thank you for posting your question here on Fixya.com.
Check the stator for a ground-fault using a megger or a ohm meter. If it smoked it is likely even an ohm meter will show a ground; if it is not grounded check for resistance across the line connections. A typical single phase motor will be about 1 ohm. If it is zero ore some number below .5 the winding is shorted.
A winding that smokes is nearly always best to be replaced. Even if you get it running again it is only going to be for a short time. I would not change the horsepower if the pump had been keeping the pool clean prior to the mechanical and/or electrical trouble. If you do you'll need a new impeller too since changing one without the other is pointless.
Was the pump leaking as you began to have these troubles? Have you confirmed the incoming line voltage is 220V and stays at least 208V or more under load? You may have had an underlying problem with voltage drop or a leaking seal that caused the failure that you will want to address to prevent this from happening again.
