1. Vacuuming large debris through skimmer without using a leaf trap.
A leaf trap has a bag inside for catching debris and is placed between the end of your pool vacuum hose and the skimmer. It keeps leaves from clogging your skimmer line when you vacuum.
It's OK to not to use a leaf trap as long as you are vacuuming small things that can't clog the skimmer line, but never go without it when sucking out acorns, sticks, large quantities of leaves, etc. This can lead to a service call to unclog the skimmer line.
C;ick here to get details about the Pentair R211084 186A Clear Leaf Trap
that our service techs have been using for years. It's the best on the market!
2. Vacuuming algae or large amounts of dirt with multi-port valve set in "Filter" position.
The "Filter" position is the correct
multi-port valve setting
for vacuuming a relatively clean pool. That is the setting we use on
our normal weekly cleaning vacuum jobs. However, when vacuuming a pool
that has just had it's mesh safety cover removed and is covered with a
layer of fine dust, the multi-port valve setting should be "Waste".
This also applies to a pool covered with algae or lots of dirt. If you use the "Filter" setting in these cases while vacuuming, you will notice the dust (or algae) blowing right back into the pool through the returns in the wall of the pool. When we are called in to help solve pool problems, and we see a bright fluorescent green colored pool water, we know this mistake has been made.
If you have a 2 position valve (slide valve) or a cartridge filter with no valve, you need to have a Jandy 3 way valve plumbed into the line between the pump and the filter if possible in order to bypass the filter and do a vacuum to waste. Call us if you want us to do the plumbing for you. Another way is to hire us to bring a portable pump and do the vacuum job for you.

See mistake #2 above. The results are the same. Fluorescent green pool water because the fine dustlike particles have blown back into the pool. Automatic cleaners like Kreepy Krawly, Baracuda, or Polaris are great for keeping a clean pool clean, but not for cleaning up a pool that needs to be "vacuumed to waste" the old fashioned way.... with a hose, a vac. head, and a pole.
4. Accidentally draining the pool through the backwash line.
Pools are often accidentally drained when the filter valve gasket fails on a multi-port valve after the backwash of a sand filter.
This mistake is easy to avoid if you have a flat backwash hose that rolls out on the ground where you can simply look to see if water is continuing to come out after backwashing, when the filter valve is set back into the "Filter" position. If it is, simply shut off the pump and get the leaky valve fixed.
When your backwash line is hard PVC that disappears under ground, this leak can be difficult to detect. Often times, that hard pipe leads to an opening at the street curb where you can go to see if leaking water is coming out the end of the pipe after backwashing. However, sometimes there is a trickle of water coming out at the curb that lasts for 5 or 10 min. and then stops. Is that trickle going to stop or not?
We like to plumb a PVC union into a horizontal section of the PVC backwash line near the valve, so that the line can be separated to easily check for leaks. If there is no trickle of water at this union, your filter valve is not leaking. Watch the following video.
5. Not brushing the pool.
I know we sound like your dentist....."Don't forget to brush!", but this is extremely important. In fact, if you had to choose between a vacuum head and a brush to keep your pool clean, choose the brush! Better yet, use both.
Brush the pool once each week during the pool season. Brush the sides and the bottom of your pool, pushing everything toward the main drain. The vacuum head can't dig in deep to discourage algae like the brush can. Use a PVC bristle brush for routine brushing, not a stainless steel brush which is too abrasive for weekly cleanings. Make sure the one you buy has an aluminum handle like the one pictured above.
6. Buying a leaf skimmer instead of a leaf rake.
Look in the back of a pool service tech's work truck and you won't find a leaf skimmer. Instead you will find a leaf rake. Why? A leaf rake will do everything that a leaf skimmer will do and a lot more.
Try dipping a couple of leaves off the bottom of your pool with a leaf skimmer on your pole. Very difficult!
Our advice...get a leaf rake instead of a leaf skimmer. The leaf rake is the one with the red frame and the black net in the photo. Don't buy the cheap one! You get the quality you pay for.

8. Allowing your skimmer basket to "float up".
When skimmer baskets are brand new, they come with some sort of weight that sinks the empty basket under water into its proper position in the skimmer. When that weight is lost, many people continue to use the basket. Sometimes the basket floats up when the pump is turned off and continues to float when the pump is turned back on, which allows debris to be sucked underneath (rather than through) the basket and then directly down the skimmer line which often causes clogged lines. Watch the video below for some useful skimmer dumping tips.
Put a large rock into the basket to weight it down if you have
lost the weight. MAKE SURE the rock is LARGER than the hole in the
bottom of the skimmer so if the basket cracks the rock can't be sucked
down the PVC line! Don't use any metal object that can rust as a
9. Vacuuming pool with filter valve in "backwash" position.
When a pool is vacuumed with the sand filter valve in the "filter" position, the dirt and debris that passes through the pump ends up inside the filter on top of the bed of sand which is where you want it.
When a pool is vacuumed with the valve in the "backwash" position, the dirt ends up underneath the bed of sand. The pool will clean up nicely like this......until the valve is turned back to the normal "filter" position. That's when all of the dirt and debris (that was just vacuumed out of the pool) blows back into the pool through the returns. UGLY!
10. Ignoring the leaves and dirt in an open winter pool.
During the winter, a pool that is left uncovered needs to have leaves removed on a regular basis. Weekly while the leaves are falling heavily, then at least once a month afterwards. The pool will also need to be vacuumed to waste a couple of times to remove the accumulating dust.
When the leaves and dirt are ignored, staining can be the result,
or at least a difficult spring clean-up. If you need help with these
chores, give us a call!
11. Failing to use a wire brush on black algae.
Black algae is the most difficult algae to get rid of, but it is not that big of a deal if you act quickly. We are going to assume that your water is balanced (see point #1 under Pool Maintenance Mistakes ).
Yes, your water can be balanced and still get algae unfortunately. Black algae is round and black and won't brush off with your nylon pool brush no matter how hard you try. We have learned to hate the stuff!
Get a stainless steel pool brush like the one sold on Amazon in the phot above....(no,not your rusty grill brush or paint removing brush from your tool closet because those aren't stainless steel and will definitely stain your pool)....and thoroughly brush the black algae.
This only applies to gunite (cement) pools because a s.s. brush will harm all other pools. Notice, the algae still won't brush off but you have scratched into the protective outer layer of the black algae so the chemicals can kill it.
Now, treat your pool with an algaecide made specifically for black algae like Robarb Black Robacide which comes in a 32 oz. bottle. Follow the dosage printed on the bottle.
If you catch it in it's early growth, one treatment will solve your problem. In some cases it will take multiple treatments. In extreme cases, pools are sometimes drained and treated with acid and power washing to get rid of black algae.
12. Hooking up a vacuum hose full of air.
Your vacuum hose must be "primed" each time it is hooked up to a vacuum head and before it is attached to the skimmer suction. If this is not done, the pump will suck air from the vac hose which can cause the pump to loose prime and stop pumping. The hose must be submerged in such a way that it fills with water completely before vacuuming.
Start with the vacuum hose attached to the vac head on the end of your pool pole. Place the vac head into the water on the deep end of the pool.
Begin shoving the vac hose underwater starting at the part closest to the vac head and working your way back towards the open end of the hose. When this is done properly, water will be pouring out the open end of the hose by the time you get to it.
Now your hose is ready to attach to the skimmer!
12. Turning off pump before dumping a full skimmer basket.
Unless your skimmer has a weir in it, you should dump the skimmer basket before turning off the pump. A weir is a plastic flap in the opening to the skimmer that springs closed when the pump is turned off to keep debris inside the skimmer. If you turn off the pump without a weir, the leaves and debris will escape into the pool.
13. Not making sure the pump is priming properly after emptying the pump basket.
After emptying the pump basket, tightening the pump lid, and turning the pump back on, your pump should begin visibly moving water after 15 seconds or so. Look through the clear lid of the pump pot to see if water is coming in through the PVC pipe that comes up from the ground and attaches to the front of the pump pot. If the pump pot does not begin to fill with water after a few seconds, get a bucket of water and pour into the pump pot, then quickly tighten the lid and turn the pump back on. This is called priming the pump. This should do the trick, but once again, make sure water is moving through the pump.
If your pump is left running "hot and dry", your equipment can become damaged due to the excessive heat that will soon build up since no water is cooling things down.
