How do I backwash my Hayward Sand filter?

When the filter pressure rise 8-10 PSI over the clean starting pressure it is time to backwash. Turn the pump off and rotate the multiport valve to backwash. Turn on the pump and the dirty water will flow out the waste line. Once the water runs clear in the valve’s sight glass, turn off the pump. Rotate the valve to rinse. Turn on the pump for 20-30 seconds. This will clean out the plumbing lines and reset the sand bed. Turn off the pump, rotate the valve to filter position and begin to filter. Take a reading of this new clean starting pressure, so you have a reference point for the next backwash cycle. Water may need to be added to the pool to replace the backwashed water.

What’s the first step I should take before I begin digging my pool?

When considering what you’ll need to make your project a success, don’t forget the most important first step for any outdoor home improvement project: calling 811 before you dig.
As any professional will tell you, smart digging always means calling 811 before every job.
Homeowners often make risky assumptions about whether or not they should get their utility lines marked, but every digging job requires a call – even “small” projects like planting trees and shrubs.
When you call before you dig, you’ll prevent unintended consequences such as injury to you or your family, damage to your property, utility service outages to the entire neighborhood and potential fines and repair costs.
After all, do you really want to be the person who knocks out the neighborhood’s cable service during the big game?

The underground utilities in my yard were marked with different color flags. What does these colored flags represent?

Each color indicates a universal color to what is buried below ground.
Red – Electric
Orange – Communications, Telephone/CATV
Blue – Potable Water
Green – Sewer/Drainage
Yellow – Gas/Petroleum Pipe Line
Purple – Reclaimed Water
White – Premark site of intended excavation

Why should I dial 811 before I begin digging my pool?

Don’t gamble with your safety — if you’re a professional excavator or a homeowner, smart digging always requires a call to 811. Knowing where underground utility lines are buried before you dig will help protect you from injury and prevent damages to utilities, service disruptions and potential fines and repair costs. Whether you’re planting a tree or shrub, or installing a deck or pool, every job requires a call—Even if you’ve called before for a similar project. The depth of utility lines varies, and there may be multiple utility lines in one common area. Marked lines show you the approximate location of underground lines and help prevent undesired consequences such as injury, service disruptions to an entire neighborhood, or costly fines and repair costs.

Does swimming pool water harm grass and shrubs around the pool?

No. Chlorine in a pool is one to three parts-per-million (1ppm – 3ppm). This is very similar to the city water that comes out of our faucet, and people have been watering their gardens with this for years.

How will energy-efficient products make a difference in my backyard and my power bill?

Depending on the size of your pool, filtration equipment, and heating requirements, your energy driven equipment may operate up to 12 hours per day to properly circulate your water for effective filtration. A small increase in efficiency can yield larger savings later; therefore, the right pool equipment is essential to your power bill. Whether you’re building a new pool or replacing existing equipment, your equipment selection can save you a significant amount of money in the long run.

What would my annual savings be if I select a variable speed pump?

Depending upon utility rates, pool characteristics, and equipment selected, your savings can be significant. It is possible to recoup the premium cost of an upgrade from standard equipment to energy efficient equipment in the first year of operation. For example, a system featuring an energy efficient high performance pump, LED Lighting, and an induced draft high efficient heater can deliver a savings of over $900 annually compared to a standard equipment setup.

Why should I purchase pool chemicals from a professional pool store instead of a big box retailer?

The main reason that you should purchase chemicals from a professional pool store instead of a big box retailer is the knowledge and expertise of the pool professionals. Your swimming pool is a huge investment. You want to be sure that you are purchasing the right chemicals and treatment to prevent problems in the future.

In addition, professional pool retailers offer reputable brands that are proven in the industry to function consistently and efficiently. You can damage your liner or gunite pool or hot tub by using poor quality chemicals, which can cost you much more money in the long run. Not to mention the ill effects some of these can have on your skin, hair, and eyes!
