Congratulations on the installation of your new Cannon Pool! Thank you for your purchase. With a little bit of maintenance and upkeep, your new pool will perform wonderfully for many years to come. Our expert team of "Pool Gurus" here at Cannon has assembled this quick guide to make pool maintenance a breeze!
 

Weekly Pool Maintenance

Providing proper care for your pool does not require a genius, it simply requires consistent attention to the little details. Pools are not hard to care for, but they can be rather unforgiving if you let up on any area of the pool's needed maintenance.
With over 40 years experience in the field of swimming pool installation and maintenance, we have come up with a maintenance plan that is easy to follow. It takes about one hour per week on the typical pool if you do the maintenance visit in its entirety.
  • Step One: Preliminaries - 5 minutes
    Empty skimmers, net surface.
  • Step Two: Vacuum the Pool - 25 minutes
    Use your vacuum or leaf bagger to clean the bottom.
  • Step Three: Pool Chemical Care - 10 minutes
    Test water chemistry and make adjustments as needed.
  • Step Four: Pool Equipment Care - 10 minutes
    Empty traps, backwash (if needed), check for leaks.
  • Seasonal Maintenance
    Pool equipment care that will extend the life of various components.
 

Pool Maintenance Preliminaries

Begin your pool service routine with some preliminaries. These are the things that you need to do first, and as you work through the process, you will see exactly why.
1. Empty the Skimmer Baskets - so that debris will not float out of the skimmer and get the pool dirty again as you are trying to clean it.
2. Net the Surface - to remove as much floating debris as possible so that it does not fall to the bottom.
3. Scoop out Large Items - if there are any larger items in the pool (stones, toys, etc.) in the bottom of the pool, scoop them out with the net. You do not want to vacuum out anything large that may clog your hose or your skimmer lines.
4. Spray off the Deck - again this is to keep the leafy material from blowing into the pool. It also makes things look really nice once you are done.
 

Vacuuming the Pool

The largest part of the pool service process is cleaning the dirt and debris off of the bottom of the pool. This is normally done using a pool vacuum, but in some cases, a leaf bagging device may be needed. Here is the process of setting up and using a pool vacuum.
1. Assemble the Equipment - connect your extension pole to the vacuum head. Then connect the swivel cuff end of the vacuum hose (the other cuff is stationary) to the vacuum head.
2. Bleed the Vacuum Hose - before you hook the vacuum hose into your skimmer, you need to get all the air out of it. If you don't, you will suck a bunch of air into your pump and you may lose prime (suction) on your pump. Extend the pole and put the head into the water, place the stationary cuff onto the skimvac plate. Then take the stationary cuff with skimvac plate attached and place it over the return to fill with water. Once you see the air bubbles stop rising from vacuum head, remove the hose from the return and cover the opening with your hand to keep air from entering the hose.
3. Connect to the Skimmer - place the hose and skimvac plate into the skimmer. Move quickly to avoid letting air back into the system. It is best to put the hose over the deck and into the skimmer, as opposed to putting through the skimmer door. This keeps the hose from floating out if the pump loses prime.
4. Adjust the Valves (if applicable) - if you are vacuuming from one intake line (i.e. a skimmer), it is important to close down the other intakes (additional skimmer or a main drain) in order to force adequate suction to the skimmer from which you are vacuuming. If you don't restrict the other intakes, the suction to your vacuum head will be insufficient and it may not vacuum properly.
5. Vacuum the Pool - use forward, slightly overlapping slow strokes, keeping the head of the vacuum under the water. Do not let the vacuum head come out of the water.
When you are done vacuuming, shutoff pump, and pull the vacuum head, hose and pole out of the water. Be sure to pull the skimvac plate out of the skimmer and then restart the pump. If pressure is higher than normal, backwash and rinse per Page 7 instructions. If the area you are vacuuming is ridden with debris and/or mustard algae, you can vacuum on the waste setting rather than filter (water will not travel through filter body). Before vacuuming to waste, fill the pool above the skimmer as water will be lost during the process, and continue to fill the pool with water while vacuuming.
 

Pool Chemical Maintenance

This is the part of pool maintenance that many pool owners dislike the most. Many pool owners perceive pool chemistry is complicated, when in fact it typically is not.
1. Test the Chemicals - using the supplied test strips, test the chemicals on the following schedule:
  • Chlorine, Total Alkalinity, pH, Stabilizer (Cyanuric Acid) - Two times per week
  • Calcium Hardness - once per year after pool opening
  • Salt (only for Autopilot Salt Chlorine Generator customers) -as needed

    For calcium hardness, bring your pool water sample to your nearest Cannon Pools location, so a staff member can test it for you. Most strips will not test for calcium.
2. Make Adjustments - add chemicals as needed to bring chemical levels up the recommended levels:
  • Chlorine: 1.0 - 3.0 ppm (part per million)
  • Total Alkalinity: 80 - 120 ppm
  • pH: 7.2 - 7.8
  • Stabilizer: 30 - 50 ppm (60 - 80 ppm for salt pool)
  • Calcium Hardness: 100 - 200 ppm, is the suggested range for calcium hardness in vinyl liner pools. Please note there is no need to go above 200 ppm.
  • Salt: 3000 ppm

    Remember the pool should be free from swimmers while adding chemicals, and after adding chemicals to allow the pool chemicals sufficient time to dissolve and dilute. You may re-open the pool once the chemical levels are within the proper ranges. All chemicals should be added through the skimmer while pump is running except where directed otherwise on chemical container (ex. Muriatic Acid, which goes directly into the pool).
 

Pool Service Equipment

Taking care of the pool equipment will insure that it takes proper care of your pool. The circulation and filtration system must be kept in proper working order. This requires a small amount of attention each week as outlined in this section.
1. Empty the Pump Trap (strainer basket) - turn off the pump, close the intake valves and empty the trap basket. Inspect the basket closely and replace if it is damaged in any way.
2. Check for Leaks - look carefully around the equipment area to make sure that there are no leaks that may damage the equipment. Pump seal leaks should be repaired ASAP.
3. Backwash or Clean the Filter - when the pressure on the filter gauge rises 8-10 psi above normal operating pressure, it is time to backwash the filter (DE and sand filters) or disassemble and clean the filter (cartridge filters). When backwashing, remember to rinse after.
4. Clean the Screen to the Autopilot salt system (not on all pools) - with pump off undo the union, remove screen and clean any debris. When done, replace screen and hand-tighten union.
 
Occasionally, the equipment will require preventative maintenance items that are covered in the next section.
 

Seasonal Maintenance

The pool equipment requires more in-depth maintenance on a periodic basis. These are preventative maintenance items that help to extend the life of the equipment and insure dependable operation.
1. Pool Filter 
Sand Filters - change the sand every 5-7 years (best done prior to pool opening)
DE Filters - disassemble and manually clean twice per season
Cartridge Filters - replace the cartridges every 1-2 years
2. Pool Pump - lubricate pump lid o-ring with a silicone-based lubricant, like LubeTube once per month. This allows for easier removal of pump lid when empting the pump trap.
3. Multiport Valve (if applicable) - disassemble and lubricate the seals on the valve with LubeTube. This will help them to operate smoothly and avoid premature wear and tear.
4. Valves (if applicable) - make sure the valves operate smoothly and fairly easily. Some valves can be disassembled and lubricated with LubeTube.
5. Autopilot Salt Chlorine Generator (if applicable) - the unit needs to be calibrated after pool is opened. To accomplish this bring a water sample to Cannon Pools. One of our knowledgeable pool professionals will test your salt level and walk you through recalibrating your Autopilot.
 

Waterway Sand Filter Valve Function Guide

FILTER - Set valve to FILTER for normal filtering. Also use for regular vacuuming.
BACKWASH - For cleaning filter. When filter pressure gauge rises 8 - 10 psi above normal. Stop the pump, set valve to BACKWASH. Unroll backwash hose (make certain it is straight with no kinks), start pump and backwash until water in clear fitting is clear. Approximately 2-3 minutes or less depending on dirt accumulation. Proceed to RINSE.
RINSE - After backwashing, with pump off, set valve to RINSE. Start pump and operate for about 30 seconds. This ensures that all dirty water from backwashing is rinsed out of the filter head, preventing possible return to the pool. Stop pump, set valve to FILTER, and start pump for normal filtering. Roll up backwash hose.
BYPASS TO WASTE - To bypass filter for draining or lowering water level and for vacuuming heavy debris or algae directly to waste.
BYPASS TO POOL - Water is recirculated through the pool system bypassing the filter.
CLOSED - Shuts off flow from pump to filter. Do not use this setting with pump operating.
WINTERIZE - Holds valve open so no moisture collects in valve head. Used only during winter storage.
 

Water Chemistry Tips

Regardless of sanitization system, the key to good quality water is pH and alkalinity balance. Alkalinity is the pH buffer, or "backbone" of pH. If the alkalinity is off, the pH will be inconsistent. Always correct alkalinity before adjusting pH. If the pH is off, consequences can include: chemicals added to the pool not working properly, damage to pool liner and/or equipment, cloudiness, scale, algae, irritation to skin and eyes.

Stabilizer (Cyanuric Acid) is very important if using Cannon quick tabs, Poolife Brite Stix, or salt. Stabilizer should be added to your skimmer slowly, and do not backwash or clean filter cartridge for 4 days after adding. Stabilizer is like sun block, but for chlorine. Too little, and chlorine dissipates at a faster rate. Too much, and the chlorine becomes ineffective.

Phosphates have become a source of water chemistry problems. Phosphates are food for plants, therefore contributing to cloudy and green pools. Phosphates are added to the municipal water supply to prevent calcification in plumbing. They also come from sun tan lotions, detergents, and runoff from yard fertilizers. If you are experiencing cloudy / green water, bring in a sample to be tested for phosphates. There are products you can add to remove them.

For reoccurring water problems, consider adding a borate into the water. Borates are compatible with any sanitization system. Pools with borates have softer-feeling water, a more consistent pH, a reduction in scaling, and limited algae.

Cannon Quick Tabs:
  • 1 tab per 8,000 gallons into the skimmer basket daily.
  • Maintain stabilizer between 30 - 50ppm.
  • Shock every 10-14 days with Cannon liquid chlorine, Cannon granular shock, or Turbo shock at a rate of 1 bag or gallon per 10,000 gallons.
Poolife Brite Stix:
  • 1 stick per 5,000 gallons into the skimmer basket every 10 - 14 days.
  • Maintain stabilizer between 30 - 50ppm.
  • Shock every 10-14 days with Cannon liquid chlorine, Cannon granular shock, or Turbo shock at a rate of 1 bag or gallon per 10,000 gallons.
Salt:
  • Maintain a level of 3000 ppm salt in the pool.
  • Salt pools are more susceptible to high alkalinity and pH, so it is recommended to keep muratic acid at home to counter this.
  • Maintain the stabilizer level at 60 - 80 ppm.
  • -Chlorine is produced only when the pump is on and no debris interrupting water circulation. Run pool a minimum of 8 hours per day, clean pump basket, skimmer basket, and manifold drain screen regularly. A Check Flo alert usually indicates that these areas need to be cleaned.
  • The purifier % fluctuates on its own based on water temperature, and the Autopilot regulates this efficiently. To change purifier % manually, press the up or down arrow on the home screen and then press select on the desired %.
  • Press boost for 24 hour shock. Hold boost for 8 seconds for a 72 hour shock.
  • If pump is being controlled by the Autopilot, it will shut off after a "boost" and you will have to manually turn it back on unless the timer(s) are being used.
Baquacil:
  • E-guide, help line, and troubleshooting on http://www.baquacil.com/.
  • Maintain sanitizer level at 50 ppm
  • Add oxidixer weekly at a rate of 1 gallon per 10K gallons.
  • Add CDX weekly at a rate of 1 pint per 10K gallons.
  • Use a Baquacil brand filter cleaner at least 3x per season.
TEST YOUR WATER WEEKLY. MAINTAIN pH AND ALKANITY BALANCE. BRING A WATER SAMPLE TO ANY CANNON LOCATION FOR COMPLIMENTARY TESTING.
