This is the overall look of the pool. - - - Updated - - - This was shot when the leak detection company was finding the leaking spots. The largest crack is at the place of the diver.

Thanks for the questions. The condition of decking, coping and waterline tile looks good. no cracks on the floor. Only three cracks on the bottom half of the side wall. cracks are not aligned. I think there was only one crack last year, the two smaller ones started to show up this year. The...

Thanks Gwegan. What can be the causes of gunite crack leaking? Should I have a structure engineer take a look? I did contact a gunite contractor, and he offered to reinforce the 3 cracks and then replaster the whole pool. The 3 cracks will have 5 years limited warranty, while other areas of the...

Thanks Joyfulnoise, Called a plaster company just now, and he is coming to take a look. I am wondering if replastering the pool is a good way to fix crack leak?

Thanks! I am living in the north CA. Besides fiberglass, any other options to permanently fixing a crack leaking gunite pool? The companies I talked told me neither replastering the whole pool nor fill the cracks with some materials won't last. - - - Updated - - - They said fiberglass is more...

I am not 100% sure, as I purchased the house last year. The house was built in 70s, and the pool guy told me the pool was built in 70s as well. - - - Updated - - - The pool is in the SF bay area, and there were some earth quakes since last year, which I guess might be the causes. How to...

Thanks Borjis, The leak detection company I used told me that fixing cracks only would be a temp fix, and had no warranty, and could last as short as one year. The longest crack is about 6 to 8 ft. The other two are about 4 to 6 ft. Thanks

Hi Everyone, My in ground gunite pool has 3 cracks on the side wall, and is leaking 1 inch water per day. A pool company suggested me to use fiberglass to resurface the whole pool to fix the leak, and they provide a warranty of 5 years. I am wondering if this is a common approach to fix a...

Yes, I did test it. The overnight chlorine lost was less than 1ppm. If they are still alive, should I raise FC to 10 again (given the cya is 2), or just keep FC at 3 and they will die eventually?

Previously, my pool had quite some yellow algae. The water was very cloudy. I shocked it twice, and have been maintaining chemicals at the correct level. (FC 2~3, CYA 20, PH 7.5). Now the water is crystal. The algae are dead (no CC at all). However, there are still some black dead algae at the...

Thanks you all. Had someone clean it. It's indeed a DE filter. I am going to keep it as it for now. And see how painful is it to maintain it without a valve.

Yes, seems it was not installed properly in the first place :( Is it worth the efforts to add a valve to it? or just keep it like this and do a thorough cleaning once a year? I am not sure how many more years it can last. By looking at the manual, I think it was installed in 2004. Probably I can...

The manual left by the previous owner is for "Pro-Grid Vertical Grid D.E. Filter Series". There is a tag on the top of the filter, which is attached. I can see "DE2420MRZ1" at the bottom of the tag. I googled "Hayward DE2420", it seems to be a DE filter :(

Thanks, they are really helpful. - - - Updated - - - That's a good idea.
