After our recent cold spell and subsequent two days of freeze protection running,my spa spillover rate is greatly reduced. Noticed pressure side Pentair valve is about 1/3 closed. Any thoughts on what’s happening here?

Freeze guard came on for first time this season and noticed as it cycle to spa/falls. The falls do not run. Spa runs and falls light on but nothing running from falls. This has never happened in 16 years. Do not use falls feature much but has always run when switched on. What do the pros think...

I’m having a continuous problem with my spa draining to pool level overnight. I’d posted previously on this and have replaced the check valve, replaced all o rings in both suction and return valves and I still have same problem. Any thoughts on where this leak might be? Thanks for your time.

Attached spa water level has been dropping to pool level overnight. Replaced check valve thinking it was the culprit but level still dropped as before. What’s next?

First complete readings this spring as follows: Ph 7.8 FC 8 CC 0 CH 600 TA 110 CYA 45 Temp 77 (water) Salt 2850 CSI 0.44 Added 32 oz 31.45 acid. Did not make other adjustments till I consulted with the pros on the forum. Obviously my CSI is too high. CH went higher in a mostly dry Spring...

My StaRite cartridge filter unit has been leaking from several places for a while now. The assembly is original and little over 15 years old. O ring has been replaced and clamps absolutely tight. I'm guessing it's just past it's prime. They are not cheap, but unless someone has a better idea, i...

Readings 9:30 am: Ph 7.5 FC 5 CC 0 CH 475 TA 90 CYA 70 Salt 3450 Temp 87 I had this problem much worse back in May and SLAMMED for 4 days and cleared it up nicely. Even though my FC/CYA ratio is good, seems like this dust creeps back in , mostly in hot tub and a corner or two, when FC gets...

What is considered a “safe” upper limit for FC to get into the pool?

Have reoccurring dusting of algae on pool walls and hot tub. Just tested and don’t see anything way out of range. See below: Ph 7.8 Fc 5 Cc 0 Ch 400 Ta 90 Cya 80 Temp 80 Salt 2950 doesn’t make any sense to me but what do I know. Any thoughts from the pros?

After the Texas blizzard, trying to get back running. When main pump is turned on, I have flow in both skimmers, Polaris up and running, falls flowing, but nothing from any of the 4 returns in pool. Cleaned filters before attempting restart and pressure is about 5 lbs higher than normal. Thoughts?

Never had algae a outbreak in over 14 years, but last week or so I keep seeing a dusting of green algae. I’ve brushed several times and checked FC/CC and FC hasn’t been below 4 and 0 CC. Dumped 121 oz bleach in yesterday and brought FC to 11 and still no CC. each time I brush, I stir up more...

While Harvey has created much pain and angst down here, we have been fortunate so far...have been successful in keeping pool drained enough so no big problems with overflowing. I have kept FC ok by adding bleach, but SWG is running very low and I have dumped all salt I have in during last few...

This pressure side cleaner has been a real workhorse for about 5 years or so I did tune up on it last spring, replaced b/u valve and check valve and all was well. Just noticed it not moving this morning. Booster pump is running fine but when I disconnected from wall, noticed very weak water...

My attached spa is once again leaking down to pool level. This happened last summer and after replacing the check valve for the second time in ten years, it stayed at the right level with the pump off. I've noticed one of the 3 way valves is not making it's complete 180. The other 3 way was...

Turned to spa mode last night and found the spa drained. Put into service mode this morning and turned pool on to fill spa then put in spa mode to check on Jandy valve rotation and sure enough the spa side turned correctly, but other 3 way "chattered" but would not turn. Is Jandy shot or is...

FC is staying high with SWG set at 5%. See #'s below. PH 7.5 FC 9 CC .5 CH 375 TA 80 CYA 90 Temp 58-60 Running pump 8 hrs/day Why does FC stay this high at 5%? Thoughts? Thanks!

Having joined TFP this past spring, I have had a sparkly clean and trouble free pool all summer and have thoroughly enjoyed the process of regular testing and listening to all the ooos and aahhs of a clean, good looking pool. PH 7.2 FC 6 CC 0 CH 425 (fill 75) TA 60 (fill 275) CYA 80 Temp...

I recently replaced the Jandy check valve to stop the spa from leaking down overnight with pump off and it did not fix it. Would one of the Pentair valves be the culprit or do I need to look elsewhere? I have attached a pic of my equipment pad. Thanks Bob [/URL]

Here are my numbers from 4/13 right after I joined TFP and got my TS100 test kit: FC 15 CC 0 PH 8+ CA 425 TA 110 Salt 3850 Here are my current numbers: FC 5.5 PH 7.5 CH 375 TA 90 CYA 70 Right after I got my first readings, I gave the SWG a good acid bath and removed all the scale and turned...

Given the rain we've had lately, I am a loss as to why the SWG is still indicating all is fine with 3600 reading and no errors. I just did the Taylor test this a.m. and it showed 3000. I'm certainly more than inclined to take the Taylor test as authentic and add a sack of salt, but does anyone...

Here are my current readings: FC 6 CC 0 PH 7.2 TA 80 CH 350 CYA 90 Pool calculator says 37lbs of boric acid and was about to add when I noticed my CSI says -0.61 and mousing over says corrosion of plaster likely. What about these numbers throws this CSI into the mix and do I need some further...

My attached spa has begun leaking down to pool level overnight when the pump is off. This happened some years ago my PB replaced what I think was a check valve. Is this what I'm needing? Thanks in advance!

Does anyone know if this valve at the pool wall is supposed to release 1) some constantly 2) only if it is defective? My cleaner is very slow and will not climb or run strong as when new. It is only 3 years old and I've replaced a defective backup valve already and will replace the two feed line...

Ok, I just got my TS100 and here we go: FC 15 CC 0 (duh?) PH 8+ CA 425 TA 110 Salt 3850 And I'm thinking this water cannot be this far outta balance yet these are the numbers. My SWG has been at 40% and usually this is fine till the summer when I kick it up to 60% and that usually keeps...

After a lot of reading on this site, I've proclaimed that after having this pool for almost 9 years I am tired of being hosed by the pool stores and ready to handle ALL the testing and maintenance. From what I've read, there are many knowledgeable people on this forum with a lot of patience...
