Swimming Pool Draining Procedure

Swimming Pool Draining Procedure
The storm drain system and sewer system are two completely separate drainage systems. The storm drain system flows directly to the Los Angeles River, which eventually discharges the water into Long Beach Harbor without any treatment. The sewer system takes all household wastewater from toilets, showers and sinks and routes it through your plumbing system into the Los Angeles-Glendale Water Reclamation Plant. Once there, it receives three levels of filtration treatment before being discharged into the Los Angeles River.

Therefore, the preferred method of draining your swimming pool is to the sewer system because the water will be treated before it is discharged into the Los Angeles River. Oftentimes, homes are equipped with a sewer clean-out which can be utilized for draining your pool.

If the sewer system is not accessible, then pool owners should dechlorinate their pool water by allowing the water to sit in the sun and not add any chlorine for 10 or more days and verify the following prior to being discharged to the street:
• The residual chlorine can not exceed 0.1 mg/L (ppm)
• The pH is between 6.5 & 8.5
• The water is free of any unusual coloration
• There is no discharge of filter media
• There is no discharge of acid cleaning waste
• Any pipe connection to the storm drain system has permits from the city or county having jurisdiction

Compliance with these guidelines can be verified using a pool testing kit. In addition, if time does not permit allowing the water to sit 10 days in the sunlight, you may purchase dechlorinating chemicals from local pool supply companies.
By ensuring compliance with these criteria, you will make a significant contribution toward keeping pollutants out of Los Angeles County’s creeks, streams and receiving waters and help to protect organisms that are sensitive to pool chemicals.

Solar Heating for Pool & Spa

Solar Heating FAQs

(For more information and to set up an appointment, visit our recommendation for Solar Heating - Suntrek Solar Systems and make sure to tell them LA Pool Guys recommended you!)

http://www.suntreksolar.com/default.asp

How does a solar pool heater work?
A solar pool heating system uses your pool’s existing filter pump to circulate water through the system. A diverter valve diverts the water so that it flows through the many small passages of the solar collector where it is warmed by the sun. This warm water then flows back to the pool until the pool has reached your desired temperature.

Can these collectors also be used to heat a spa?
Yes. Simply set your spa circulation cycle at the end of the day and set the thermostat for 104 degrees.
What about the environment?
Gas heaters pollute the air directly with carbon dioxide and other emissions. Heat pumps pollute indirectly as a result of pollution released during electricity production. In contrast, solar requires no fossil fuels. It is a clean, abundant energy source that will never contribute to pollution or the depletion of natural resources.
What special maintenance is required on a solar pool heater?
Under normal circumstances, no special maintenance is required during the swimming season. Our quality electronic controls allow you to "set and forget" the solar heater. It is recommended, however, that you shut off and drain collectors during the winter. This process takes just a few minutes.
Do the solar collectors have to face south?
The solar collectors should be installed where they can be fully exposed to the sun for a most of the day. Depending on the angle of the mounting surface, east, west and flat facing systems can function equally as well if sized properly for the pool.
Do the solar collectors have to be mounted on the roof?
The solar collectors are generally mounted on the roof however, the collectors can also be ground mounted or installed on a patio cover.
How do I control the temperature of my solar heated pool?
If you choose a manual system, a diverter valve allows you to turn your solar system on or off. Another option is an automatic heating system, which works like the thermostat you use for home heating & cooling. Simply set the electronic controller to your desired water temperature. If the temperature of pool or spa is lower than desired, the controller turns the motorized valve to allow the pool or spa water to flow through the hot solar collectors. When the pool or spa water reaches the same temperature as the collectors, the controller turns the valve again so the pool or spa water will no longer flow through the system.
Will I need a pool cover?
With a properly sized solar pool heater, a pool cover is not required to keep the pool at a comfortable temperature during the warm swimming season. However, a pool cover does help retain heat at night and prevent evaporation loss.
What size solar heating system will I need to heat my pool?
There are many factors. The most important factors are the size of your pool and orientation of the solar collectors. Other factors include how long you want to extend your swimming season, the wind across the pool, and whether you use a pool cover. The general rule of thumb is 80% surface area of the pool.
How much would a solar pool heater cost for my pool?
Solar pool heating system prices for a residential pool can range anywhere from $2,500 to $7,000. The location and size of the pool, location of the solar collectors, desired temperature and season, and type of pool equipment determine system size and costs. Because of all the variables, it is impossible to give an accurate estimate without careful inspection of the site. To set up an appointment for a free analysis and estimate contact us at 800-292-7648.
How much will my solar heater cost to operate?
Since the sun energy is free, there are no operating costs to heat your pool.
How long will the solar equipment last?
Our collectors can be expected to last between 20 to 25 years. Our Solar collectors are covered by a 15 year warranty.
