Backwashing and rinsing your pool filter clears out trapped dirt and debris. Always turn off your pool pump before touching the multiport valve to avoid damaging internal gaskets. Perform these steps when your pressure gauge reads 8 8 to 10 psi above normal.
In order to prevent residual blow back into the pool, once you've finished backwashing it's highly advisable to rinse the filter. Just as the backwash lifts and flushes the sand, the rinse resets the sand to its original position for optimum filtration.
Backwash your sand or D.E. pool filter for 2 to 3 minutes, or until the water in the filter’s sight glass runs clear. Immediately follow this by rinsing for 30 to 60 seconds to settle the sand and clear out any remaining debris. Always turn the pump off before changing valve positions.
Run the backwash until the water in the sight glass (or the water you can see exiting) runs clear. Rinse Cycle: After backwashing, switch the filter to the rinse setting. Run it for 1-2 minutes to clear out any remaining debris and prevent dirt from re-entering the pool.
Turn off your pool's pump and filtration system. Set the filter value to BACKWASH and ensure the handle locks in place. Turn the pump on and you'll see water flow through the view glass. Wait until the filter view glass is clear.
If you don't rinse after backwashing, residual dirt and loose debris trapped in your filter system will be pumped directly back into your pool. This creates a cloudy "puff" of dirty water that exits through your return jets, undoing the cleaning you just performed.
Pool shock is a chemical treatment that helps break down contaminants – such as leaves, dirt and debris, even oils from your skin -- that can gradually build up in your pool water. Shocking your pool as part of your weekly pool maintenance routine will help keep your water clear and balanced.
I wouldn't get into it without hip waders until the water is clear. I'd skim the surface with a netted leaf removal pole, shock and chlorinate until clear, vacuum the bottom, and then check the chemical levels to ensure they're within acceptable limits. You may also have to add an algecide.
All pools lose some water daily due to evaporation. Under normal conditions, expect about 1/4 inch per day, with weekly losses typically ranging up to 2 inches at most. However, factors like high temperatures, low humidity, wind, and pool activity can increase evaporation, leading to greater water loss.
When you backwash a pool, the water comes directly from the pool itself. The pool pump pulls water from the skimmer and main drain, forces it in reverse through the filter to dislodge trapped debris, and expels it out of the waste line.
Generally speaking, pools lose approximately 1/4” of water per day on average, though this can vary due to factors like wind, temperature, humidity and of course, the pool's total surface area.
Backwashing too long alone isnt harmful...running out of water running dry, stuff like that is. Sound like just needs to be fully primed. it will seem to suck air if not primed and air relief is open. Fill the basket with water then close the pump lid, then start the pump.
Here's our recommended backwashing process:
Move the handle on top of the filter to the “backwash” position. Switch the pool pump on. Watch the sight glass on the filter, it should turn dirty and then slowly (usually 1 – 2 minutes) become clear again. Switch the pool pump off.
Clean your pool in this specific top-to-bottom sequence: skim floating debris, brush walls and stairs, vacuum the bottom, empty skimmer baskets, and clean the filter. Always perform physical cleaning before testing and balancing the chemical levels, such as shocking and adjusting the pH.
With time the sand in your filtration system will break down into smaller particles and get out into the pool. These small particles will have no problem going through the filtration system and in the end, get mixed with dirt. This could be a reason your pool gets dirty even after you have vacuumed it.
If you fail to rinse after backwashing, the overall quality of your pool water can decline. Backwashing a filter aims to remove contaminants, but if you fail to rinse the filter after backwashing, you are at risk of putting those same contaminants into your swimming pool.
You backwash first, then rinse.
No, you should never vacuum a pool on the "Backwash" setting. Backwashing runs your filter in reverse. Doing this while vacuuming will push the unfiltered dirt and debris backward, clogging your filter media or tearing the delicate internal grids/laterals.
Baking soda (sodium bicarbonate) acts as a natural buffer that raises both your pool's total alkalinity and its pH. It prevents severe pH fluctuations (known as "pH bounce"), clears cloudy water, prevents equipment corrosion, and helps your chlorine sanitize more effectively.
Pool pumps typically last 8 to 12 years, but premature failure usually stems from overheating, water leaks, or debris blockages. Common culprits include a failing motor (often due to worn bearings), electrical shorts, dry running caused by air leaks, and impeller damage from clogged debris.
Just as long as you need to, until the water is running clear at the end of the hose, or in the sight glass, which some valves have for viewing the waste water clarity. The larger the filter is, the longer it should be backwashed.
A backwash should last for 1 to 3 minutes, or until the water runs completely clear through your filter's sight glass. Always turn off the pool pump before changing the valve settings, and follow up your backwash by rinsing for 30 seconds to settle the filter media.
