Pool Covers
- Using a pool cover regularly reduces evaporation
by 90 to 95 percent.
- Without a cover, an average pool of 5m x 10m loses
about 1 inch of water per week in the peak of summer.
This can add up to an annual water loss of 26,500
litres.
- One of the most important benefits of using a pool
cover can be enhanced safety.
- You can cover a pool without being concerned about
gaseous exchange, unless you are using chlorine gas.
If you are using chlorine gas, you should let it air.
Pumps
- A pump should be able to circulate pool water at
least every 24 hours, but every 8 hours is preferred.
- Most existing pool pumps are oversized for the size
of the pool and plumbing, which reduces filter effectiveness
and causes more wear and tear on plumbing.
- For the average 50mm plumbing pipes, a pump of only
1/2 horsepower is needed. Many pool owners have bigger
pumps, which dramatically increases electrical pumping
costs. For example, a 1/2 horsepower pump will cost
about $300 per year to run, while a 3/4 horsepower
pump will cost $450.
Filters
- Each time you backwash sand and diatomaceous earth
filters you could lose up to 2000 litres of water.
Water Quality
- Proper chemical balancing can prevent and cure most
water clarity problems.
When is it appropriate to dump your pool water?
Not as often as you may think. Pools can often go 10
or more years without draining and refilling. Here are
some guidelines:
- When the total dissolved solids (tds) get too high.
- Water quality problems often can be solved by draining
only a portion of the water.
- If you have to drain your pool, make sure you take
steps to prevent the pool shell from popping out of
the ground.
