Frequently Asked Questions


General Pool Questions Answered

How long do I run my swimming pool?

Run your pool 8-12 hours during daylight hours.

My pool is losing water?

  1. For Inground pools- if the pool was just opened and it held water all winter most likely it is in the lines.
  2. First check around filter and out backwash hose.
  3. If the pool has been opened and started losing water to cut down on unnecessary we recommend that you put winter plugs in all returns and gizmos back into skimmers to block any water from going into your lines. Mark on your skimmer faceplate the waters height. If the water goes down it is in the liner/ faceplates/ faceplate gaskets/ skimmer/ main drain(if not a Snyder pool)
  4. If it doesn’t go down it is in the lines- start to take winter plugs out 1 at a time and that will give you the location of what line the leak is in.

How do I Vacuum my pool?

  1. Take out your hose, vacuum head, skim vacuum, and pole assemble together.
  2. Take assembled vacuum equipment to return that is closest to skimmer. Place vacuum head into water, put skim vacuum plate over return, leave it on return till all air is out of hose.
  3. Once hose is filled with water attach to skimmer basket in skimmer. You will feel it get pulled down taught to basket and you are now ready to vacuum.
  4. Inground customers- turn off skimmer that isn’t being used. If pressure is too much turn on other skimmer.
  5. Filters with multiports- leave multiport on Filter. When done vacuuming backwash for 90 seconds and rinse for 5 seconds.

Vacuuming with Polaris

  1. Hook up Polaris to designated return
  2. Turn on Auto Cleaner Red Valve
  3. Shut off the rest of the Return/ red valves
  4. Do not touch any other valves (Polaris runs off of pressure)

I have none or little pressure/ suction?

  1. Make sure water is ¾ way up the skimmer.
  2. Do you have lots of air bubbles? If so need to check all o-rings/gaskets or unions where water could be getting into system. Lube with jack or magic lube. Vaseline will corrode orings. Most common place is pump strainer basket.
  3. Are you vacuuming? if it is only happening while vacuuming it is vacuum equipment.
  4. If none of these apply need a service call.


Cartridge Filter FAQ

My Pressure Gauge is reading really high?

Need to pressure wash & Soak in Filter Perfect (sold at Retail Store) for 24hrs. Or we can pick up for Cartridge Cleaning ( we will leave spares)

How do I clean my Cartridges?

You will need to get a plastic trash barrel fill it with water and add Filter Perfect (read bottle for correct dosage) you will need to soak for at least 24 hours and then power wash. Make sure you don’t put the power washer to close to the grids or cartridges this will cause them to rip or tear. Cartridges will need to be cleaned daily when pool has algae.

How long do Cartridges last?

6-10 years

Sand Filter FAQ

How long does sand last in a sand filter?

It last 7-10 years. The older it is the more compact it gets and filters better.

Why do I have sand blowing back into my pool?

One of the lateral assemblies has a crack in them. The entire internals need to be replaces. Also replace sand when replacing lateral assemblies.

I have water coming out of my backwash hose?

You will need to replace the spider gasket that is located under the multiport handle. You will need to remove all the screws and remove the key way assemble and the gasket will be located on the bottom. Every multiport has a different size and design for a replacement so you will need to get the part number before coming into the store to buy a new one. A silicone will need to be added to the spider gasket before it is placed back into place.

Or you can put a ball valve on the backwash line to stop the water from draining out.

My Pressure Gauge is reading really high? Or how do I backwash?

Filter needs to be backwashed. Turn off power to pump- turn multiport to backwash always going clockwise- then turn power back on- backwash for 90 sec or until site glass is clear. Turn off power again move multiport to rinse for 5 seconds. Turn off power again and move multiport to filter.

D.E. FAQ

What is D.E.?

Diatomaceous Earth (D.E.) is a soft, crumbly, porous sedimentary deposit formed from the fossil remains of diatoms.

Diatomaceous earth, also known as D.E., or diatomite, is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder. It has a particle size ranging from less than 3 micrometres to more than 1 millimetre, but typically 10 to 200 micrometres. Depending on the granularity, this powder can have an abrasive feel, similar to pumice powder, and has a low density as a result of its high porosity. The typical chemical composition of oven-dried diatomaceous earth is 80 to 90% silica, with 2 to 4% alumina (attributed mostly to clay minerals) and 0.5 to 2% iron oxide.

D.E. is blowing back into the pool?

One of the DE grids has a rip in it. Take out the DE manifold and inspect. You can replace just one of the grids at a time.

Pump FAQ

My pump won’t keep a prime?

This means that water will not stay in the pump strainer basket.

  1. Check water level in pool, make sure it is ¾ way up the skimmer opening.
  2. Make sure it is pulling water from the pool. Check both skimmers for suction.
  3. Make sure no air is getting into system. Magic or Jack lube Pump Basket O-ring.
  4. Check to make sure that the impeller is spinning freely. If it isn’t then you will need to take apart the pump and free the impeller. (see below for instructions)
  5. If the impeller is spinning freely- get your garden hose, shut off power to motor, fill up the pump basket till it is overflowing, put the cover on quickly and turn power back on. It could take up to 20 minutes to catch prime as well. Keep in mind most pumps are now self-priming so this shouldn’t be an issue.
  6. If all of these helpful hints aren’t working call the retail store for a service call.

My motor turns on but no water is moving?

Check the impeller making sure it is free of debris. Shut down all power to the pump- take off pump cover- take out basket- at the bottom of the strainer basket is a hole either stick your finger or a screw driver in the hole and see if you can freely spin the impeller.

Can also take the bolts off the Strainer housing and get right to the impeller.

If it is stuck try and free it- might need a new impeller or if the shaft isn’t spinning it might mean a new motor or take it to Morse Electric in Gardner.

Chemical FAQ

My Pool Has Algae?

First add 1lb of shock it and 8oz per 10,000 gallons of mustard algaecide. Let pool run 24 hours then add 1lb of shock it per 5,000 gallons everyday till clean. Make sure you are vacuuming or at least brushing the algae off the walls every day.

How much sustain do I add into my pool?

Add 1- 3in tab per 10,000 gallon and 1- 8oz scoop of energizers per 5,000 gallons

My pool won’t hold Chlorine?

  1. Do you have Algae? If so then you need to shock your pool with 1lb per 5,000 gallons everyday till clean.
  2. Check your stabilizer level. Ideal level is between 60-80, to maintain a 1-3ppm chlorine level. Or on the flip side if your stabilizer level is too high it will eat your chlorine in the pool. Water will need to be drained and refilled.
  3. When was the last time you added chlorine? If it wasn’t within 24 hours it needs to be added.
  4. Check for nitrates.

My water turned green after I added chlorine?

  1. That means there was a metals reaction in your pool. When chlorine or any balancing chemicals are added to water with metals in it the water color will change. You will need to lower the chlorine level to 0ppm and add 1qt of metal magnet per 10,000 gallons. Let it run for 48 hours without adding any chemicals to the water. To assure that the metals are out of your pool take a bucket of water from the pool and add a small amount of shock it to the water. If it doesn’t change continue to add your balancing chemicals as directed. If the water color changes even a small tint you will need to add another bottle of metal magnet to the pool.

Salt Generator FAQ

How do I know my salt generator needs to be recalibrated?

  • Pool is perfectly balanced. If salt level on test strip says salt is low and generator says between 2700-3500 and chlorine level is between 1-3 ppm or higher DO NOT RECALIBRATE.
  • Salt test strip and salt level in water do not match
  • Water temperature is at least 65

How much salt do you need for your salt generator to run?

3000 ppm of salt is the recommended amount. Helpful hint: 50lbs. of salt per 2,000 gallons to get to 3000ppm or 50 lbs. of salt per 10,000 gallons will raise it 600 ppm. (Remember always test your salt level with a salt test strip or bring a water sample into the retail store.)

How do I clean my Cell

  • Turn off circulation pump.
  • Loosen unions as indicated on the cell manifold.
  • Put a winter plug (1 1/2” threated plug) in the base of the cell.
  • Once capped, fill the cell with water about 2-inches from the top of the cell blades.
  • Fill the rest of the cell with Muriatic Acid. This results in a 1 to 4 solution. Always make sure to add acid to water and not the other way around. (Use gloves and eye protection when handling harsh chemicals).
  • Let the solution sit inside the cell for 20 minutes.
  • To dispose of the acid solution it is ok to pour into your pool water.
  • Rinse the cell with fresh water and dry off the cell terminals before reattaching the cell cord.
