How to clean pump basket without blowing air through the system...

When my PB showed me how to clean out the Leaf Vac and pump baskets shown below, he didn't do anything other than remove the lids, clear out the debris, replace the lids and turn on the pump. When he did this, I don't remember seeing much air being pushed into the pool but when I do the same steps a TON of air comes out of the returns and IFCS heads. This can't be good for the filter right?!

I've tried filling the baskets and quickly tightening down the lid, but I can't fill it fast enough.

Should I try closing this valve before opening them? If so, what position does it need to be in?

When you break the seal (pump lid, filter relief valve, etc) air will get into the system if your pool equipment is above the pool water level. The air being pushed out will not harm anything.
 
Almost every video I've watched says to fill the pump basket up with water before replacing the lid so as not to allow too much air into the system.
If your pump is above the water level of your pool, the water you add to the pump basket drains to your pool. You can add some if you like, but it really does nothing to assist in priming the pump.

Yes, this is exactly what is happening. That is why I asked if I should be closing the valve in front of the two baskets to prevent the water from draining back into the pool. It's something I saw mentioned here and in numerous videos online, but if it is indeed harmless to push that much air through the filter I guess I won't worry about it!

But the air isn't entirely harmless...it raises my *perfect* pH level by a tenth every time!
 
The valve in front of the pump never actually closes. It just balances water between skimmer and main drain. The same thing happens to my system when I open the pump basket lid. It's nothing to worry about. As the pump is priming, after startup, open the air relief valve on the filter to release as much air as you can.

Good to know, thank you!
 
I remove my pump's lid, clean the basket while the water all gurgles out (back to the pool). Replace everything and start the pump to watch it prime, which it does, no problem, without any extra water added. Once the priming is done, and the pump ramps back down to the programmed RPMs, I crack the bleed valve on top of my filter. Sometimes a little air escapes, sometimes not. I believe that's the way it's all supposed to work.

Pretty sure the tip "fill the pump basket up with water before replacing the lid" is intended to assist pumps that might have trouble priming, nothing to do with trying to keep air out of the filter or elsewhere. Which, as you've learned, is not possible when you open up the pump. If your pump primes on its own, then don't bother with adding water. One less thing to do.

My system has a check valve on the inlet side of the pump, so no water leaves via that route when the lid is opened, but the pump basket will get siphoned dry by way of the filter and the pool returns. If I just put the lid back on and start the pump it will prime but it takes a very very long time. Also like queenofchlorine I have a hose bib plumbed into the line between the pump and the filter, and I've found the easiest trick is that after opening the lid let maybe an inch of water siphon (to avoid spills) and then open the hose bib which being higher will be the point air enters and the pump basket retains most of it's water. A lot of air ends up in the system either way, but the pump will prime much more quickly if it start with a mostly full basket.

How long does your pump prime? Mine is set at 2 minutes, which isn't long enough to get all the air out. It usually takes several minutes of normal operation with air jetting out of every head in the pool.

What made me question all of this is the statement written on top of the pump lid: "Fill with water before turning on pump." :unsure: Regardless, I feel better knowing I'm not doing anything wrong here. Thanks for your input!
 
Mine primes in about 30 seconds, maybe less. I can hear the air working its way through the pipes and the filter for maybe another 30 seconds. I can watch the bubbles pass through my check valve. I guess some of it must make it to the pool, but I never really noticed or worried about it. After the bubble noises stop, I bleed the filter.

The priming cycle is probably a set of adjustable settings in your pump's controller (how long, and at how many RPMs). But priming is only about filling the suction-side pipes and the pump with water. Suction-side pipes run from the pool to the pump's inlet. Once those and the pump are full, the priming is done. How long it takes the air to expel from the pressure-side (all the pipes and components that come after the pump) doesn't matter, and technically isn't part of the priming process.

If the priming is finishing (on the suction-side), don't mess with the pump settings as it's already doing what it's supposed to do. You don't have to worry about how long it takes the bubbles to clear out of the rest of your plumbing.

If I can still see a good amount of air in the basket when it's done priming should I try priming it longer? It clears up eventually, but it probably wouldn't hurt to just bump it up right? It's adjustable up to eight minutes. Maybe I'll add a minute and see how it goes.

I wish mine was that quick! It gulps down A LOT of air when I open those baskets. I've only done it 3 times and the amount of air that spews into the pool is alarming. At least for a newb like moi.

Mine would glug glug glug just like that. The filter is just draining and it's no harm. I was just happy I was on the sucking air side and not the spurty side.

The air from the returns was just as turbulent as yours too. You'll laugh at it eventually when a big one burps. Excuuuuuuuuuuuse YOU...... slob.

You can reduce the air out of the returns by opening the air bleed valve on the filter when priming the pump. Once a full stream of water is coming out of the valve, close it.

As RPMs increase, so does the pressure in your plumbing (just observe the pressure gauge on your filter as the pump ramps down from priming mode to normal mode). Modern PVC-plumbed systems are pretty tough, but less is more in this case. Your plumbing is never under more stress than during the priming cycle. The shorter and gentler the cycle, the better. Increasing the priming RPMs, and/or the amount of time at priming RPMs, will increase the stress on your plumbing and filter and other components some amount. Enough to harm them? Maybe not. But maybe so, over time. If you have a legitimate reason to increase the priming cycle, then so be it. But if you don't, then why do it? I actually decreased my pump's setting for priming RPMs just for this reason. If your pump primes 100% of the time, even if it takes longer than you think it should, leave it alone.

Because of the reinforcement ridges just under my pump's lid, the last air bubbles never clear out. Ideally, your pump should be clear of bubbles, but if some remain, especially if they eventually clear, then they probably aren't causing any issue. Now if you're talking about enough air to effect the pump's impeller, like starving it of water for a protracted amount of time, then that is something to address. In that case, yes, you would increase the time.

That all said, if you want to fool around with the priming settings, have at it. Just be prudent about it: the lower the RPMs required, for the least amount of time required, is best. Conversely, you don't want to go overboard with that notion, because you need the priming to be 100% reliable. You don't want the priming to fail when you're not around, as that could cost you a pump.

The amount of "gulping" is just a matter of how long the suction-side pipes are. Which is just a matter of how far from the pool your equipment pad is located. It really isn't a problem.

If it makes you feel better, when my solar heater kicks on each morning, you should see my pool. It looks like a jacuzzi there are so many bubbles. It's all the air in my suction-side pipes, plus all the air in my solar panels, plus all the air in the very long pipes that run from my pump to the roof. It's never bothered me. I can hear it from my bedroom each morning, and let's me know the sun is up, the birds are chirping, flowers are blooming and the heater just kicked on, getting my pool ready for a comfy swim later in the day! 🐦🌞🌷 It's just a matter of how you perceive it: bubbles in the pool means your stuff is working!! Life is good!!

Thanks for all your input you guys. There is so much information out there on the interwebs it can be overwhelming. I love being able to jump on here and pick your collective brains! Nothing better than hearing firsthand what other, more experienced pool owners are doing with their systems. Much appreciated!!
