Re: 100's of Questions - Pool School Extended
1) How do I find out what my clean filter pressure should be? Gauge reads between 10-25 PSI
2) How do I get the air out of the filter and/or pump? I have a gurgling sound coming from the filter and during these times, I get low return flow and low suction at the skimmer. Could this be a main drain blockage issue? Everything inside the filter was replaced 2 weeks ago. A new pump installed last season.
3) How do I make sure the pump fully primes? When I clean out the filter skimmer basket, do I need to refill with water before starting back up? I do sometimes hear/see gurgling in the pump basket/box when I turn off the pump.
4) How do I find out what speed my pump is?
5) Clearning suction lines: Do I stick a socked hose (like a sock I would wear or is there some kind of special sock?) or drain king directly into the hole inside the filter basket box?
6) Check Valve: Where is that located? What are the NORMAL valve settings?
7) Will a vinyl vac work on a plaster pool? What is the difference between the 2?
8) Tri-Chlor: Floater or directly into the skimmer basket - Which is best? And which skimmer?
9) Regarding the skimmer (s): the junk it collects is not going INTO the basket. It is just swirling around the top of it.
10) Diatomaceous Earth: Where to buy? When I first use it, do I have to pour it directly INTO the filter? I read that after the initial usage I am supposed to mix with water and pour into the skimmer but I'm confused as to how I do it the first time.
I feel like doing this

or having someone do this

because I feel like I'm
1. Backflush your filter. Before doing so: Always turn off your pump any time you change the position of the multiport valve. Turn back on after changing positions.
- Set to backflush and let the pump run until the clear sightglass shows clear water (or as clear as your pool might be).
- Set to Rinse for 30-45 seconds
- Set to Filter. Wait 1 minute and read the pressure gauge. THIS is your clean pressure reading. It might be even lower once your pool is sparkly clean.
2. The filter basket sight glass is the place to look. Are the bubbles in there all the time, even after the pump has been running for several minutes? There should be no or very few bubbles in that sight glass. Bubbles in the pump sight glass usually means you have a suction (skimmer/drain) side leak of some kind. Would need more troubleshooting for leaks.
3. To help your pump get prime after opening the basket area, fill with water using a bucket and pool water. It may reduce time to get prime again. However, even if you don't, the pump should prime within 3-5 minutes and shortly have no bubbles in the sight glass. Gurgling always happens, well always does with my system when the pump goes off.
4. Find the user/owner's manual for your pump. It's not really a relevant number. I'm assuming you're talking about RPMs as a speed. If you're referring to high and low speed for a 2 speed pump, there is a switch or it's automated by a cotnrol system.
5. Not sure what you're asking here. Are you wanting to clean out a whole line of debris or just wanting to know about skimmer socks?
6. Check valves are there to prevent back flow of water. Usually between something like a heater and the SWG. There are no settings for check valves, they just prevent back flow.
7. Vinyl vac might work OK on a plaster pool but having a head that's designed for your pool type is best. Vinyl pools use bristle head type vaccums and plaster pools use wheeled/roller type heads.
8. Trichlor is best kept dry in a bucket, for emergency or vacation use only.

Seriously though, it's best to put it in a floater. Putting trichlor pucks directly in the skimmer exposes your pump and pumping station to high levels of chlorine and low pH repeatedly. This can cause premature failure of seals in your pump and fittings. Putting the pucks in a floater to dissolve is best... if you must.
9. I use a small skimmer net or aquarium net to get the stuff that refuses to drop into the skimmer basket. Then I clean the skimmer basket.
10. First time and every time you try DE with your sand filter you mix the DE with pool water in a bucket and pour directly into the skimmer, any skimmer. I usually dump in the skimmer closest to my filter. You can get DE at most places that carry pool chemicals. Got mine at a local farm store, have seen at Home Depot and Lowes. Can get online but shipping is costly. Last resort... pool store. :ncool:
