Clean your water cooler!

If you have a water cooler, it is important to clean it regularly. How often it should be done varies with recommendations from yearly, to every 6 months to Health Canada' recommendation of every time you change the bottle. Health Canada Bottled Water Page

How do you clean your cooler? These are the steps that we use:


1)     Unplug cord and allow the unit to come to room temperature. For Hot and Cold coolers, run some water out of the hot tap after unplugging to cool the water.
2)   Remove the bottle.  Empty the reservoir through the faucets. For Hot and Cold coolers, also remove the drain plug at the back of the cooler.  Replace after the hot tank is empty.
3)      Remove the lid of your dispenser.  No-Spill tops require a little extra effort to pull off and push on. Some have a locking pin. Some require a partial counter-clockwise turn before removing.
4)      Mix a cleaning solution by adding 1 tablespoon of household bleach to 1 gallon of fresh water. Thoroughly wipe inside of reservoir with cleaning solution and a clean cloth or paper towel.
5)      Fill reservoir with cleaning solution. For Hot and Cold coolers, open the hot faucet until water comes out and top up the reservoir with solution.
6)      Spray a diluted solution of bleach and water inside the faucet spouts.  Let stand for 5 minutes, and then drain through the faucets. For Hot and Cold coolers, also remove the drain plug at the back of the cooler.  Replace after the hot tank is empty.
7)      Fill the reservoir with fresh water. For Hot and Cold coolers, open the hot faucet until water comes out and top up the reservoir with fresh water.
8)      Drain through the faucets. For Hot and Cold coolers, also remove the drain plug at the back of the cooler.  Replace after the hot tank is empty.
9)      Repeat steps 7 & 8 once more.
10)  Remove the air filter from the top.
11)  Clean the top in a clean sink filled with fresh water and a mild bleach solution.
12)  Rinse the top with fresh water, and dry with clean paper towel.
13)  Replace air filter
14)  Replace cooler top.
15)  Replace bottle.
16)  Open faucets one at a time until water runs from each.
17)  Plug unit back in.
18) Water should be chilled and hot, if so equipped in about 1/2 hour.

Reservoir Tips

Reservoirs must be properly maintained to ensure the best possible water quality. Treatment of reservoirs may harm fish, and care should be taken. 

Poorly maintained reservoir
These procedures are based on our experience with reservoirs since 1968 and are our recommendations. They should be used as a guide only. Please remember to take all necessary precautions when using chemicals.

Aeration
Dugout aeration will tend to inhibit algae growth, and will lessen the odour problems associated with anaerobic decomposition.

Taste, Odor, Color
The foul taste, odour and colour in reservoir water usually results from algae or water plants. Decomposing algae and plants on the bottom of the water produce hydrogen sulfide gas, which gives the water a "rotten-egg" taste and odour. By the end of winter, water may become black. Control of algae and plants during the spring and summer will reduce these problems.

Controlling Aquatic Vegetation
All preventative and mechanical methods should be considered prior to chemical treatment.

Preventative Methods 
Deeper dugouts with steeper slopes reduce the shallow areas where plants grow rapidly. Limit nutrients:  
  • Flood diversion dikes with gated culvert inlet.
  • Grass the water course and the area around the dugout.
  • KEEP LIVESTOCK OUT!
Mechanical Methods
  • Hand pull plants
  • drag a heavy chain or harrows across the bottom to cut plants
Polydex
Polydex is a mineral based bacteriostatic algaecide liquid concentrate that can:
  • Reduce algae, bacteria and associated toxins
  • Improve colour, taste and smell in the water
  • Reduce suspended solids
  • Reduce organic film build up in lines
It is easy to apply and quickly disperses. Initial treatment is 1:60,000 followed by periodic testing with maintenance dosages at 1:500,000

Copper Sulphate (Bluestone)
Copper sulphate can be an effective treatment for algae. It is more effective if used before the algae population becomes heavy. To apply, it may be placed in a burlap sack and dragged around the reservoir, or the water filling the
reservoir may run over the sack. The dosage is 1 to 2 pounds per 100,000
gallons.
If heavy blooms of blue-green algae develop, use caution. Another source of
water should be used for 2 weeks after treatment. Copper sulphate is toxic to fish. If you must treat a dugout containing fish, treat 1/3 at a time and space the treatments 24 hours apart. Water usage should be avoided for 24 hours.

Turbidity
Reservoirs that become turbid (muddy) will usually clear by themselves. Be
careful not to confuse colour caused by decaying algae or organic matter with
turbidity, as treatment is different. If turbidity persists, Alum may be used. The alum should be dissolved in water 1/2 pound per gallon) and spread evenly over the surface. The dosage is 10 to 20 pound per 100,000 gallons.

Reglone A (Diquat)
This chemical is used to control aquatic plants. Treated water should not be used by humans or animals for 2 weeks. Contact your supplier for correct dosage.

Granular Chlorine
More effective than Copper Sulphate for organic matter and algae is granular
chlorine. It may be simply broadcast over the surface. The dosage is 4# per 100,000 gallons. In severe cases, it may be necessary to repeat treatment in a week.

Copper sulphate treatment may be
applied at the same time for enhanced
results.

Gravel Filters 
Gravel filters installed in or beside the
dugout are not recommended. 

Floating Intakes
During the summer, 80% of the impurities are close to the bottom. A floating intake, 3 feet from the surface willcollect the best water. During winter, lower the float to below the expected ice level.
Floats may be constructed by 16' of 1 1/2" pipe coupled in a ring, or 3' of 3" PVC or ABS pipe capped at each end.

Blue Green Algae
Blue—Green Algae can be toxic. Please follow this link to Alberta Environment

Reverse Osmosis Maintenance

REVERSE OSMOSIS SYSTEM TROUBLESHOOTING

Normal maintenance includes regular replacement of prefilter and post filter. System should also be sanitized periodically. Maintenance procedures are in your manual or on our website www.holmeswater.com.

If your system is not working properly please call us to service the system. If you wish to troubleshoot on your own, you will find some steps in the owner’s manual. In order for us to diagnose problems and make recommendations without checking the unit, we need to know the following answers.  

  1. What equipment do you have? Make and Model? If you purchased it from us, we should have a record for you. 
  2. How old is the system? 
  3. Are you running out of water with the same usage pattern as before when you didn’t run out? 
  4. Is the water quality okay? 
  5. When were the prefilter and post filter last changed? 
  6. When, if ever was the membrane or RO filter changed? 
  7. Are all of the valves turned on – Main supply valve, Leak Controller, Tank Valve? 
  8. With all valves still turned on and you are experiencing the problem: 
    1. Does the storage tank feel full? An empty tank weighs a couple of pounds - full, it may weigh up to 20#. 
    2. Can you hear any water running at the unit? 
    3. Open the faucet to drain the water from the system – it should slow to a steady drip or trickle 
    4. Measure the water dripping from the faucet. You should get 1 cup in less than 5 minutes. How long to get 1 cup? 
    5. This is the best time to take a water sample for purity. What is the Total Dissolved Solids measurement? (you may need to bring a sample to our office) 
  9. Close the main supply valve, leaving the faucet turned on 
    1. With the storage tank empty, measure the air pressure in the tank using a suitable tire gauge,etc. Air pressure should be 5-7 psi if the unit is under the sink, 10 psi if it is in the basement. Air pressure? 
    2. Disconnect the drain line. 
    3. Direct any water from the drain line to a bowl or other suitable collector 
    4. Open the main supply valve 
    5. Measure the water dripping from the drain line – How long to get 1 cup? 
    6. Turn off the faucet  
    7. Does the water dripping to drain stop within a few minutes? 
  10. Don’t forget to reconnect everything and open all valves when finished. 
  11. If these instructions do not make sense to you, we suggest you have one of our certified service technicians repair your system.

These tips are provided as a convenience for our customers to provide a guide for self service. They will not apply to all systems. 

As always, be careful when working on water treatment systems. Double check that water is turned off before taking anything apart and that everything is reconnected properly before turning on the water.
