Why is backwashing important?

Last Updated: 22nd January, 2020

Backwashing is a form of preventive maintenance so that the filter media can be reused. Slow sand filters and self-cleaning screen filters employ mechanisms other than backwashing to remove trapped particles. To keep water treatment filters functional, they have to be cleaned periodically to remove particulates.

In this manner, how does a backwash work?

The backwash is accomplished by sending water down the riser tube from which it enters the filter tank at the bottom. The force of the water is such that it actually lifts the media bed, swirling and tossing the granular medium.

Likewise, what happens if you dont backwash pool? You do a backwash out of a pool. If the filter is not backwashed dirt and ?? filtered builds up and if it dies not stop the water flow rhe dirt will be discharged back int ok the pool. A good way to tell when to backwash is watch for the pressure on the input side ti increase by a few psi.

Furthermore, how long should a backwash take?

A sand filter should always be backwashed for a minimum of 3 minutes and a maximum of 5 minutes depending on the size of the filter. Backwash for at least 3 minutes, even if the water leaving the backwash line or the water in the site glass is clear.

Why do you need to backwash your pool?

" - Similar to a vacuum cleaner, air conditioner filter, or your kid's bedrooms, your pool filter collects dirt! Whenever the filter fills up with the dirt/debris it reduces the flow of water to your pool. Low flow = poor circulation which will lead to algae in the pool.

Do you rinse or backwash first?

A good rule of thumb is to backwash once the pressure displayed on your pressure gauge is 8-10 psi over the starting level. Backwashing after heavy rains, treating for algae, or when trying to clear cloudy water will keep your filter working efficiently.

Can you over shock a pool?

Start off by adding 3 or 4 gallons, and if you see no results overnight, add 3 or 4 more gallons the next day. Continue this process until you notice the water changing color to either cloudy white, light green or clear. YOU CANNOT OVER SHOCK A POOL ! The more you add, the quicker it will clear !

Does backwashing remove water from pool?

Backwashing can take only a few minutes to complete, but for a typical pool, it consumes approximately 200 to 300 gallons of pool water! So, while your filter is losing unwanted dirt and debris—your pool is losing a ton of water.

Where does the backwash water go?

Use the backwash to water grass or any area on your property that will allow water to percolate into the ground. Backwash pools directly into the private sewer cleanout on your property instead of into the storm gutter.

How do you backflush a pump?

Should I run my pool pump when it rains?

Note: If you had a lot of rain, your pool may have extra water. This is good if you need to vacuum at a lot of debris off the bottom of your pool to waste. But if you have little or no debris, pump the excess water by turning your filter to “waste,” hooking up your backwash hose, and turning your pump on.

What is the difference between backwash and rinse?

Rinse runs water in the same direction that normal filtering does. Backwash runs it through the sand in the opposite direction. Rinse is to clear any dirt out of the clean side of the sand before you start sending it back to the pool.

What should the pool filter pressure gauge read?

A pool system's pressure is generally measured at the filter's pressure gauge; the usual range is 10 - 25 pounds per square inch (PSI.) When you installed your filter, or after a thorough cleaning, make a note of the “clean filter” PSI. This rating will be used as a benchmark for pressure tests down the line.

Should I backwash after shocking pool?

If your pool is very dirty, it may need MANY pounds of Granular Shock over a period of days before the water clears. Green or cloudy water will quickly clog a filter, therefore you may have to backwash your filter many times a day until the pool clears. THIS IS NORMAL ! Remember, you cannot over-backwash a pool filter.

How often should a pool be shocked?

Always make sure that the filter system is running while shocking the pool. Some pool owners choose to shock their pools once every 1-2 weeks as normal maintenance. This is a great way to keep your chlorine level up and prevent algae growth.

What happens when you backwash a pool?

When you backwash a pool, you send water backward through the filter, and out the waste or drain port. This forces all the debris caught in the filter to dislodge so you can easily remove it and restore the filter's normal functioning level. Think of it like using a strainer in your kitchen sink.

Why does sand come out when I backwash?

If most of the sand comes through the holes of the lateral, the sand is too small. Your pump may be too large or the sand level too high in the filter. When the filter is backwashing the water flow can cause the sand to rise high enough and overflow into the standpipe, which will allow the sand back into the pool.

How many hours should I run my pool pump?

Swimming pool pumps should be run an average 8 hours a day to properly circulate and clean your water. The pump should push your entire pool in gallons in this 8 hour period of time. However, often times swimming pool pump horse power is overrated for their size swimming pool.

Does backwashing remove chemicals?

From vacuuming to maintaining proper water chemistry levels, swimming pools require a consistent upkeep. One way to keep your swimming pool's filter system in working order is through the use of backwashing, or reversing the flow of water through the filter to remove any built-up contaminants.

Why is my pool dirty after I vacuum it?

If dirt is reappearing at the bottom of your swimming pool after you've vacuumed it your pool's filter may be working poorly. Pool filters often work poorly because they're in need of cleaning. If you have a sand filter for your pool you need to make sure that the sand is sharp and freshened up.
