  1. Is this a public or private pool? I would not see any different for a surge tank for 1 filter and not the other. If it is a public pool there are federal laws now regarding protect against entrapment by a drain or drains in the pool floor. here is a link to new laws http://www.cpsc.gov/businfo/vgb/vgpsa.pdf I know some pools are build were the suction side it attached to a basin or tank then the pump pulls water from that.
  2. Hi, I'm going to have to replace an installed catridge filter system for a pool that has a cubic capacity of just over 40,000 gallons. We're going to put in a sand filter and a guy who came by to check the pool out said that we are supposed to have a surge tank inline with pools like mine. So tell me, just what does a surge tank do for me, and is it necessary bt Florida code to have one installled with a sand filter system? I say sand filter because that is what appears to be the best efficiency for the least maintenance cost and what we have decided to put in. Please feel free to be as descriptive in all areas when answering this question. Thanks
  3. First off you better check into any requirement to were the pool is about a public pool. Most times the filter is downrated for public pools because they want a high turn over rate of water. Look at this chart from Hayward http://www.haywardnet.com/inground/product...fm?ProductID=92 looking at the first model in the chart it can turn over 15,360 gallons in 8 hours for a public pool and 40,320 for a residential pool. That is a rating they give just because of the presumed higher bather load in a public pool even if it is the same filter. I know were I live a public pool must be turned over every 8 hours. I take care of a 15,000 gallon public pool and it has a sand filter rated at 47,000 gallon in 8 hours. I know the owner will not want spend any more money but a bigger filter is probably needed and change to a sand filter. All the public pools here use sand. Here is link to what I would install http://www.haywardnet.com/inground/product...fm?ProductID=28. the s360sx model. I appreciate that extra info. The 8 hour turnover rate for this cartridge system is 12,000 gals in 8 hours. That seems a bit inefficient to me for a 45,000 gal. capacity pool. That filter system model I promised to add info about is available to me now. It's a Clean and Clear Model #160317. There's nothing in the manual I have with it that refers to limitations based on liquid capacity. That seems unusual to me. The only thing I see that relates to what the filter can handle is which cartridge element handles in "square footage of filtered area" it only has listings of elements for 50 sq ft. to 200 sq. ft. I don't know if there's some different formula that calculates "square footage of filtered area" but that makes no sense at all to me. Being pretty much ignorant on this subject, I would just figure that if you have any piece of equipment like this, it would tell you what the filter will efficiently handle in cubic capacity, not square footage. As far as gallons per hour passing through the filter, it seems logical that you've got to be able to filter X gallons per hour over a particular time period. I mean the filter should be able to clean the water with this maximum amount flowing through. You obviously have to filter the entire volume in a time frame that will keep any crap from multiplying in your pool at a rate faster than the pool can filter it out. Anyway, you see my problem perhaps a bit more. I have also told the owner that I would recommend that he just get rid of the cartridge filter and go to a sand filter or even, back to a DE filter. After all, before they put in a cartridge system, they had a DE system and didn't have nearly the problems we have now. Those problems didn't begin until after the cartridge system was put in. I'm just trying to make what I have work, since the owner doesn't seem to be ready to come off the bucks to change out the filtration system again. Any other comments/assistance would be greatly appreciated. I'll also look into that sand filter but I'm sure cost is certainly a factor.
  4. Hi there, I'm new here so please bear with me. I work for an apartment complex that has an inground pool that measures 24 ft. x 44 ft. It has a sloped floor from 3 ft. to 8 ft. Now my calculations (if correct) tell me that I'm looking at a square footage of just over 1000 ft. and using an average depth (height) of 5.5 ft. to calculate cubic capacity it comes to 5808 cubic ft, meaning I should have a pool that holds just under 45000 gallons of water. With me so far? With that in mind the owner of this complex purchased a cartridge filter system for it less than a year ago. Everything I've seen that I can find doesn't make any reference to an effective filter area in square footage of 200 ft. tops. I've also seen talk that cartridge filter systems are not very good to have for pools over 30,000 gallons. This info says also that if you do you should buy a system that is the next step up from what is recommended because cartridges aren't very efficient. Other info leads me to believe that catridge systems are best used for above ground pools or spas and such. After all this, the pool store that the owner bought the system at tells him that the filter is adequete for this pool. Based on the info about the pool can someone make any recommendations on a make of a catridge filter system that would be right for the above specs. I know it would be helpful to have the make and model of the current system, but I can't find my paper that I wrote it down on right this second. I'll get it up here tomorrow if someone could tells me anything about that particular unit as well. I can say that the cartridge in the unit is about 3 ft tall and I'm having to pull and spray it about every two weeks and when I do it a;ways full of green algae even tough the pressure gauge only gets to about 1.5 when I pull it. Right now I just can'r seem to keep pace with the cleaning to keep the pool open for any significant amount of time. Since I'm in Jacksonville, my pool will probably not close for the "winter" until late November or early December so I gotta do something about this. Any useful info would be greatly appreciated.
