Thank you for posting your question here on Fixya.com.

The motor is likely failing. It may be a small part such as the capacitor or the starting switch, but could also be more severe such as the winding itself. You will also want to examine the shaft where it passes thru the pump and motor and look for signs of rust from a pump seal leak.

If you are not familiar with testing these parts your best bet would be a local electric motor repair shop to see if the motor can be repaired or if it would need to be replaced. They should also be able to ensure there is no pump damage.

SOURCE: Is a Hayward cl-100 ef chlorinator the right model

The cl100 should do the job. The first thing I would do is check the chemicals. Make sure you have enough stabilizer (cyanuric acid).If it's low your chlorine will not last long at all. Check the ph and alkalinity also. Make sure you are running the pump long enough. the cl100 only adds chlorine when it's running.

SOURCE: I have a leak in my above ground sand filter,

Usually in th bottom of the filter you have two parts. The first is a piece with a screen that threads into the plastic housing. The second is a Cap with a rubber washer inside. Make sure the rubber washer is there. Do not overtighten the drain into the houseing

Thank you for posting your question here on Fixya.com.


32' round by how deep? Flow rate is how you size a filter so with total gallons you can calculate how many per minute will add up to the whole pool being turned over is 6-8 hours. The pump and filter are then sized for that required flow...Assuming the pool is an above ground ~4' average depth then total gallons would be about 24,000 gallons. For an 8 hour turnover you would need about 50 gallons per minute. The 210T, T for top mount, is designed to handle up to 44 gallons per minute and turn over a 21,000 gallon pool in 8 hours or a 26,000 gallon pool in 10.

What that basically means is that using a 210 on a pool 32 x 4 would be pushing it. It will work but you will end up backwashing more frequently which raises the overall cost of running the pool. If it is not to late a 24" filter would be better; especially if you have periods of time in your pool season where heavy amounts of debris such as pollen get into the water. A 21" filter won't handle any over a normal filtration load.

SOURCE: Model #SD-20-2N11CC WATERWAY PUMP (2HP)

Rule of thumb for a 2 HP pump using a 2 inch pipe is between 60 and 80 gallons per minute. Factors affecting flow rate is the distance between the pump and the pool, how many bends and turns and of course the condition of the filter. If you need to meet a specific turn-over rate, use the lower number to determine in the event you sould be called on the carpet.

Low speed? I am sorry. I don't know the rule of thumb on this.

You could install a flow meter, available at your professional pool supply. They are easy to install and not a lot of money. Follow the installation instructions as best as you can.

Incidently, comercially speaking, the 'turn over rate' should be around 8 hours for a public pool. Your jurisdiction may have other standards. Commercial pools should run 24 hours a day at that rate during the open season. Turn over rate means all the gallons of the pool should go through the filter in 8 hours, or all the gallons should go through the filter three times per day. Example: 16000 gallons of water in the pool, your filter and pump should be pumping 2000 gallons per hour. Studies show that it actually takes up to 5 days to get every actual 'chunk' of water to go through the filter, so, many of the 'chunks' of water go through the filter multiple times per hour. BTW, I use the word "chunks" in an effort to better paint a mental picture of what is happening. I am not suggesting your water has "chunks" in it.

Thanks for your question @ FixYa.com

Tempra 24 Keeps tripping high limit Switch

If you have already descaled your Tempra 24 Tankless water heater and replaced the flow sensor, but the high limit switch is still tripping, there could be a few other possible causes of the issue: Malfunctioning thermostat: A malfunctioning thermostat may cause the heating modules to overheat, which can trip the high limit switch. You may need to replace the thermostat if this is the case. Insufficient water flow: The Tempra 24 Tankless water heater requires a minimum flow rate of 0.5 gallons per minute to operate properly. If the flow rate is too low, the heating modules may overheat and trip the high limit switch. Check the water flow rate to ensure it meets the minimum requirement. Electrical issues: If the wiring or electrical connections are faulty, it may cause the heating modules to overheat and trip the high limit switch. You may need to inspect the wiring and connections to ensure they are intact and properly connected. If none of the above solutions work, it may be best to contact a professional technician for further diagnosis and repair. It is unlikely that you would need to replace the entire unit if the issue is isolated to a single heating module.

How salt to use for start up for a 22 x 52 above ground pool

You need to know how much salt is currently in pool...
then what is total gallons of your pool?
Round pool? 22' round?
52" walls?
Use only Pure Pool Salt, NOT Softener salt!
2700 ppm to 3400 ppm is the range for ideal levels in your pool.
check out this link...

How much salt do you put in a 22,000gal. pool?

WOW... You have a huge above ground pool! Are you planning to use the Intex chlorinator to chlorinate your 22,000 gallon pool??? If you are, take a look at the max gallon rating and how long you may need to run... Here's a chart that should help you determine how much salt to add... After adding the salt, run the pump for 24 hrs without the chlorinator to properly dissolve the salt... Don't be surprised if you need to add above 500 lbs!!!
Good luck and hope this works for you...

Can a person use a hayward de ec40 for either above ground pools or inground pools? if not why?

Yes as long as you are sure to match the flow rate of the pump to the filter. The biggest limit will be the low maximum flow rate the EC40 has. It will clog up to fast if installed on a larger pool...inground pools are generally larger (more gallons of water) than above ground. The pumps are more important to match as far as using inground rated units for inground pools and above ground for inground. Filters only care about flow rate and overall volume of water to keep clean.

I've been reading the blogs and have ascertained that the intex filter is too small to properly circulate pool water for optimum salt chlorination. i have a Krystal Clear system model CS8110 and would like...

You have about 8588 gallons of water in your pool ... One inch of water contains about 159 gallons in your pool. You should consider a 6 hour turn over rate. I recommend a high rate sand filter with at a minimum 1.5 sq feet of filter area. You need to move about 24 gallons a minute to achieve the 6 hour turn over rate.

Continue your research with these figures at hand.
