This brutally hot summer with basically zero rain has shifted either my concrete pool deck (most likely) or my pool--see attached pics. The pool and deck is 25 years old, and I had it replastered with new coping a year and a half ago. I haven't had any issues with this at all until just this...

So I am having a lot of debris getting past my DE filter and clogging up my salt water generator. I've opened up the filter and all the screens look good and there don't seem to be any cracks or holes in the screens or the piping. I also changed out the spider gasket on the multiport valve...

I have an Autopilot Pool Pilot Digital 220 which stopped working after a major freeze and power outage x 4 days (Texas winter storm damage from last year). Whenever I try to run it, the unit gives a warning "Purifier Off -- Check Flow". If I disconnect the manifold using the unions then...

Hey, I have a Autopilot Dig-220, and am getting the Warning Low Amps--Cell? error. I have a RC-42 that is 5 1/2 yrs old, the readings are: Salt 3000ppm Temp 85 deg F 32V 3.0A (was 2.8A then I cleaned the cell) Power level 2 The cord connections are tight and not loose. I'm guessing it's a...

Ok, a bit of an unusual situation, for at least for me: There is a wasp nest behind the cover of the wall unit portion of my Autopilot Dig 220 SWG. I know this because not only do wasps constantly come in and out from behind the cover, but I used one of those in wall fiberoptic cameras to see...

Anyone know of any inexpensive (including shipping) sources of calcium chloride that I can buy online? There are no local stores here that carry it (Houston never has it let alone in the summer...). I've been looking online for a while and haven't found something that is not too expensive...

I have an Autopilot Digital and LOVE the temperature compensation feature. Is there any other SWG with this feature? My impression is no. Also, I have the Autopilot on a pool, and am contemplating an SWG on a spa (separate body of water) as adding bleach is getting really old. The spa is...

Ok, so I've got this Stenner pump which is pumping bleach into a spa. The tank has a lip on the top (see picture) surface underneath the pump which accumulates water when it rains, so I sealed the drainage hole from the pump into the tank with caulk. But when I did that, the tank could not...

Hi everyone, I have a 2-speed pump powering a waterfall that just burnt out. Don't ask me why the original owners had a two-speed motor wired only for one-speed for a waterfall... The motor makes a hum, but does not run. The impeller turns freely, and I tried changing the capacitor (the...

Ok, another chemical storage thread. I understand that you shouldn't store muriatic acid and bleach close together, but what about pool salt, calcium chloride, and dichlor? Can I store those with the bleach? I assume the dichlor should be safe with the bleach, but what about the others? Can...

Wanted to ask a question: what is a reasonable price to hook up just the electrical to a pump? I replaced the motor to my pump (changed from a one-speed to a two speed motor), and the electrical wiring is different. What do you think is a reasonable amount of money to pay (parts and labor) for...

Hi everyone, Just got my burnt out motor on my Hayward Tristar pump replaced by Warehouse pool supplies. However, the original was a one speed 2.0 HP with service factor 1.35 for a 2.70 total HP pump. The one they installed is a two-speed pump with a 2.0 HP and service factor 1.10 for a 2.20...

Ok, I backwashed a spa yesterday, but I forgot to release the air in the filter while I was doing it. Backwashed for 4 mins, rinse for 1, turned to filter, added DE, ran the filter for 2 hours fine. Never released air in the filter. Today, during the scheduled filter time, I noticed the pump...

If you use a Stenner pump to add acid everyday, are you supposed to dilute the acid in the tank? And what ratio of dilution should you do? I seem to recall reading the instructions of the Rolachem saying you have to dilute acid. Thanks!

Ok, so I got this Glacier Pool Cooler thing to help cool my pool water. I had a pool guy install it as I have zero plumbing/electrical experience. He attached the intake to the pool cooler to the former intake of a Polaris booster pump. Apparently the water flows from the pump, through the...

My borax level is low, and my TA is high. A thought occurred to me: can I lower TA faster by lowering pH with muriatic acid, wait for a few hours, then add borax to increase pH, then repeat? Aeration seems to take a long time to raise pH.

Was thinking of getting a Glacier Pool Cooler to cool my pool as Houston summers make the water so warm. Tried the fountain route but didn't work well enough. The company says that the piping has should be 2" from pool to equipment or there may be "balancing problems". I only have 1.5" from...

Hey everyone, I wanted to install a Stenner pump to my ~2500K spa to automate chlorine addition. The spa with a solar cover currently consumes ~10 oz bleach per day in the peak summer (100 deg now!). I'm assuming it consumes around 2-3x that without the solar cover. I run my pump only half an...

So I going to get one of those glacial pool cooler things to cool my water down as the pool gets pretty warm in the hot texas summers. My question is in terms of installation; I'm assuming it goes on the return line. Should I put it after or before my salt water chlorine generator? I have a...

Was thinking of automating my spa by installing separate pumps for bleach and muriatic acid. Both of these would be added to the return line after the heater I'm assuming. Now, does it matter which order they are put in, and do they have to be a certain distance apart?

Have a separate spa and pool (both outdoor and inground), and we probably won't use the spa for ~half a year (while it's hot). I've still been maintaining both, but was wondering if there was a way to close the spa during the hot months as we really don't use it. The spa is freeform (close to...

I have 5 returns in my pool, and in order for me to use the PoolSkim, do I need to block 4 of them and install the PoolSkim in the 5th? And will that affect pump efficiency? My last question is does the PoolSkim work well with the pump on low flows?

Is it bad to bring FC levels to just under shock levels each time you add chlorine in order to reduce the frequency of chlorine additions? For instance, I have my spa at a CYA of 60. By bringing it up to FC of 20 ppm (shock is 24ppm), I can get 6-7 days before it creeps down to the minimum of...

So, got an Intelliflo VF recently, and had a question about adding chemicals. Do I need to increase flows when adding chemicals? I have the flows at 15gpm, sometimes less. Can I just add chemicals over a low flowing return without changing speeds?

I'm trying to pick a good spot for my spa in terms of balancing the rise in pH with a too negative CSI. Numbers (TA was 170 so I was adding acid to bring it down): pH 7.1 TA 40 (was over aggressive...) CH 340 CYA 75 Borates 50 Temp 84 deg F With these numbers, I get a CSI of -0.94 from the...

So the Autopilot manual says the manifold requires 20gpm minimum flow, and the trouble shooting section says the check flow light will turn on (and the purifier off) at below 15gpm. 1) So which is it? 15 or 20? 2) If the flow rates are below 15gpm yet the Autopilot light doesn't turn on and...

I have a question about the Intelliflo VF. I set the pool size to 15000 gallons, the number of turnovers to 1, and the pump run time to 24 hours. I also set feature 3 to run at 40 gpm for 2 hours for skimming (just made up that flow rate... is it adequate?). By my calculations, the skimming...

Just wanted to talk about how great the Autopilot PoolPilot Digital temperature compensation is. 1-2 weeks ago, the Autopilot had been running at an output of 25% for a water temp of 83 degrees F. FC level remained at 6ppm during this time. The past 3-4 days, the water temp rose to 90 deg F...

Ok, a relative built a 40K pool in Mexico (note: hot, sunny). There is no filtration system; it is drained and refilled once every two months or so. He vacuums it occasionally (once every several weeks) using a siphon action that draws some water out as he vacuums. The only thing he tests is...

For example, if pump run time was too short, would any organics that happened be in the pool be left there rather than filtered causing free chlorine to decline quicker?
