How do I clean my pool filter?

If you have a cartridge filter simply take out the cartridge and hose it down and put if back together. If you have a sand filter stop the pump turn the multiport valve from filter to backwash, start the pump and run it until the water in the observation bubble runs clear, then stop the pump, now turn the multiport valve to rinse, and run the pump for about 45 seconds, and stop the pump again. Return the multiport valve to filter and you are done. if you have a DE filter go to the following link for a comprehensive U tube explanation. http://au.youtube.com/watch?v=jA-an54IVLc

How do you clean pool filters?

back-washing a sand filter sand filter with amultiport valve # Turn of the pump# while pressing down on valve handle, turn it from the FILTER to the BACKWASH position # start the pump # usually there is a clear bubble on or near the multiport valve. it shows the condition of the water. at first the water in it will look dirty when it clears up, turn of the pump.# Turn multiport valve handle to RINSE and Run it rinse for about 30 seconds seconds. # Turn off the pump then move the multiport valve handle to FILTER position # Turn pump back on and note lower pressure. ----Back washing a D.E. filter with a multiport valve; # Turn of the pump# while pressing down on valve handle, turn it from the FILTER to the BACKWASH position # Start the pump# Let the water run for 2 - 3 minutes or until it runs clear. Turn of the pump.# Turn multiport valve handle to RINSE and Run it rinse for about 5 to10 seconds. Turn of the pump.# Move the handle to BACKWASH. Turn on pump again until water runs clear. do this about 3 - 4 times, going from backwash to rinse, Backwash & Rinse, to ensure a thorough backwash. # Turn of the motor and move multiport valve handle back to the FILTER position # Turn pump back on# Add 1 lb D.E. powder per 10 sq ft of filter area. Check on the filter tank. ---- Cleaning a Cartridge filter # Turn of the pump # Open the air bleeder opened, # Remove the cover, # Remove the cartridge # Hose it thoroughly from top to bottom, until all of the debris stuck to it is gone # Soaking the cartridge in a TSP (trisodium-phosphate) or similar solution can be helpful especially with older filters that can suffer from blocked pores. NOTE Do not use TSP with Baquacil or Soft Swim for sanitation.----


Do you plug in a hose somewhere before setting to back wash an in ground pool?

Notnormally You may have to top up the water a bit because the back wash process tends to lower the water level of the pool a bit bit no hoses need to be plugged in anywhere as the backwash system is part of the filtration set up. Below I have put in backwash instructions---- back-washing a sand filter sand filter with amultiport valve # Turn of the pump# while pressing down on valve handle, turn it from the FILTER to the BACKWASH position # start the pump # usually there is a clear bubble on or near the multiport valve. it shows the condition of the water. at first the water in it will look dirty when it clears up, turn of the pump.# Turn multiport valve handle to RINSE and Run it rinse for about 30 seconds seconds. # Turn off the pump then move the multiport valve handle to FILTER position # Turn pump back on and note lower pressure. ----Back washing a D.E. filter with a multiport valve; # Turn of the pump# while pressing down on valve handle, turn it from the FILTER to the BACKWASH position # Start the pump# Let the water run for 2 - 3 minutes or until it runs clear.

How do we backwash sand filter?

Backwash a sand filter with a multiport valve; # turn off the pump motor # Start by Rrotating the handle on the multiport valve from the FILTER position to the BACKWASH position, Usually in the opposite direction) # Start the pump, Usually there is a clear bubble on the sand filter and you will see dirty water running through it, Wait until this water starts to run clear. otherwise keep an eye on the water exiting if you can until it runs clear. this can take about 2 to 4 minutes. # Shut off pump motor and move multiport valve handle to the RINSE position .Run on rinse for 15 - 30 seconds. once again you can keep an eye on the clear bubble to see the water clear if you have one. # Shut off pump motor again and move multiport valve handle back to the FILTER position # Now start pump again on and take note of the lower pressure. when the pressure gets too high again it is time to backwash once again.

What is the function of the recirculate position on a multiport valve?

Recirculate allows water to circulate through the system but bypasses the filter. This allows one to keep the pool water flowing, and components like a salt water chlorinator running, even if the filter is broken.


Where is the egr valve located on a Dodge Ram 1500 5.9L?
