Question about Hayward 3/4hp Super Pump Inground Pool Pump 115/230 Volt # Sp2605x7

1 Answer

Pool water level lowering

My pool water keeps lowering. There is no leaks in the liner. I did notice that since I backwashed several days ago the pump emptys and has to fill up before the filter runs. The control handle is difficult to move to other positions. Is there something in the control value that needs to be replaced.

This depends on your backwash valve. First ck to see if you are getting any water out of the backwash line when pump is running. If this is the case your backwash valve needs to be rebuilt. If it is a dial valve you can take it apart by removeing the screws around the rim and lifting the top off. The gasket in the unit called aspider gasket will be pulled out of the slots it fits into. You need an exact duplacate for this so get all the info and take the old one to the store with you. Clean and dry the slots it fits into then apply a thin film of silicone to the bottom of the new gasket and put in place. Set the top and screw in place. then let set for a day then run. If you have a piston valve and you say it's hard to move so I think this is what you have. the top probally has a set ring on the top of the valve. If you pull this then carefully pull the top up and put a liberal amount of liquid soap in the valve body and let that sit for fifteen or twenty minutes then come back and twist gentely while pushing and pulling on the valve till it comes free. The "O" rings come in a kit and your pool store can install these for you if you bring the piston into the store. Or you can replace them yourself but they will do it for the price of the parts and can recomend a good lube for the "O" rings and show you how to apply. Lubeing these on a regular basis will keep them indefenetly. If your valve is a Hayward there will be a regestration mark on the valve top that will fit into a nocl on the valve body make sure they line up or it will give you trouble. Then just screw the top on again.

Above ground pool leak


Is this an above ground pool or an in ground pool? As a general rule you don't want vinyl to go too long without water. Water helps things stay in place. If the vinyl starts to shrink and bow inward there is a good chance that it will lose its elasticity and split when the pool is being refilled. I would advise you to go ahead and refill the pool. Leaks can be repaired underwater. In the event of a split I'd go back to the installer and pursue a new liner at his expense.

Bucket Testing to Locate Leaks In Your Swimming Pool


<span>How To Conduct a Swimming Pool Leak Detection Using A Simple Bucket Test </span> <p><img src="Bucket.jpg" />In Arizona, you can see up a 3/4" per day loss through evaporation and it is suspected that during the course of a year, that nearly 3/4 of the pool would have been replaced due to evaporation. <br /> <p><span>Evaporation will vary greatly </span><span>depending</span><span> on a several factors; water temperature, air temperature, wind, dew points, barometric pressures and just overall changes in seasons. Also, if you heat your pool, you will also notice variations in evaporation. Because of these factors, evaporation rates can fluctuate from day to day, pool to pool, and of course, from parts of the country to others.</span><br /> <p>It is amazing how many people call in with concerns of leaks in their pool. They really are not sure <i>why</i> they are concerned but something has caught their attention and caused concern.<br /> <p>Before becoming too concerned about a leak, or spending the money on an expensive leak detection, conduct simple bucket test to determine if water loss in your swimming pool is due to a leak or is just evaporation. <br /> <p>In a nut shell, a bucket test exposes water in a bucket to the same conditions as those affecting your swimming pool. By comparing the water loss in the bucket to that in the pool, it is possible to determine if the pool is leaking or if supposed leaks are just the result of water being lost to the air.<br /> <p>Before undertaking any test, make sure your automatic water leveler is turned off!<br /> Bucket Test Procedure: <ol> <li>Bring the pool water to its normal level</li> <li>Fill an empty bucket with pool water to about one inch from the top of bucket. (By filling the bucket close to the top you are ensuring that air movement over the surface of the bucket will similar to that of the pool.)</li> <li>Place the bucket on the first or second step of the pool. To keep it from floating away it may be necessary to place a few bricks or rocks into the bucket. (By placing the bucket in the pool water you are ensuring that the water temperature of each body of water will be similar).</li> <li>Mark the water level inside the bucket with a permanent marker on the outside of the bucket.</li> <li>Mark the water level of the pool on the outside of the bucket, on the pool wall, or skimmer face plate. I recommend the bucket, because then you have something tangible to look at. </li> <li>Operate the pool for 24 hours as it had been operated when a leak was first suspected, in most cases, this will be the normal run times. </li> <li>After 24 hours, make a second mark on the bucket to indicate the level of the water in the bucket and do the same for the pool level.</li> <li>Compare the two levels. If the pool water has changed more than the inside water level, there is probably a leak. At this point, you should contact a professional leak detection agency.</li></ol> <span>You are probably wondering how this works when the body of waters are so vastly different in size. It all comes down to <i>surface area</i>. No matter how large or how small, environmental factors act the same on the surface area of the body you are testing. </span> <span><br /></span> Further Diagnosis: Establishing suspected leak locations with a "Pump on/Pump off test" <br /> <p>Comparing the results of the bucket tests with the pump on for 24 hours to the results with the pump off for 24 hours can provide additional information as to the type of leaking you may be experiencing. <br /> <p>Conduct a second bucket test with the equipment sitting idle. Do the same steps as noted above. Any leaks during this time are now called <b>static leaks.</b><br /> <p>Water loss pump on &gt; water loss pump off = suspect return plumbing leaks (Pressure side plumbing)<br /> <p><b><u>RESULT #1:</u></b> Water Loss Active <b>greater than </b> Water Loss Static <br /> <p><u>PROBABILITY:</u> Skimmer/main drain or other plumbing leaks (return lines, infloor system, aerator)\<br /> <p><b><u>RESULT #2:</u></b> Water Loss Active <b>equal to </b>Water Loss Static <br /> <p><u>PROBABILITY:</u> suspect shell, liner or fitting leaks, (non-plumbing)<br /> <p>If you have an in floor cleaning system, water feature or specialty items on your pool you should also conduct independent tests with each of these in the normal operation and compare them against other results when they are not in operation.<br /> <p>These types of tests are not 100%, but they do provide you with enough information to determine if further leak detection is necessary and to provide the leak detection company with some great information!<br /> <p><br /> <p>We hope to have been of service to you!<br /> <p>The Ugly Pool Guy, <a href="http://www.wefixuglypools.com">www.WeFixUglyPools.com</a><br />

Pool loosing water?


Maybe you cannot decide if the loss of water in your pool is a leak or evaporation. If you place a bucket of the pool water on a step in the pool with the water level the same inside and ouside the bucket exactly the same and run the pool pump for a day, then you will be able to tell if youi have a leak. A leak would result in a lower level in the pool after running the pump for the day. If the levels stay the same, then it is evaoporation.

It sounds like there was a lack of water to the reservoir, which is, I assume the inlet reservoir with the basket strainer in it.
1. Is your water level in the pool high enough to keep the reservoir full?
2. There is an o-ring or gasket on the reservoir cover, is it there and lubricated so there is no air leakage?
3. Put a garden hose into the open reservoir to see if the pump moves this water out.
Do all of this with the filter set to just go back to the pool so you can see the results.
Try this and comment back.
Good Luck,

How do you backwash to lower water level with the Pinnacle pump?


The model of pump doesn't really matter,You backwash the filter by changing the position of the backwash valve (while the pump is off). If you have a D.E. filter, be sure to add fresh D.E. powder to the filter when you are back in "filter" position.

I changed my sand in the filter last month, when I opened up the pool it was full of green algae, the filter is working but I haven't had to backflush since 2 days ago. The water is still extremely cloudy...


If the water is beginning to clear up, it doesn't sound like you have done anything wrong. You might just need to let your pool filter keep working. I would
a) make sure that your pH, chlorine, and alkalinity levels are correct. An inproper balance of chemicals might be causing the cloudyness.
b) Be sure Vari-Flo valve is set on “Filter” position.
c) Operate filter for longer periods.
d) Make sure that the flow rate through filter is sufficient.
e) Continue to backwash frequently.
Try this for a few days and let us know if you still don't notice a change.

No water coming out when I backwash. I cleaned


water level must be about the discharge (eyeball) in the pool to back wash. Check the hose connections to make sure that hoses off the the filer head are going to the right place Look for the words "Pump" , "pool" and "waste" molded into the valve. I've seen it a number of times where "Pump" and "pool" were connected the wrong way.

Water loss in pool, but no hole in liner


The only problem is that ther is a leak in the liner. Generally at the bottom where a rock or debris has made a small hole. They can be patched but the pool will need to be drained. Call your local pool service company.
