Even The Doc Gets Nailed!

[PoolDoctor]

Several months ago, the multiport valve on my sand filter stuck, and wouldn't budge. I then tried to unbolt it off the filter and disassemble and clean. Loh and behold, one of the retaining bolts snapped due to rust / age, and I was left with a perfectly useless filter. As it was approaching cold season, I just let the pool go. To keep mosquitos down, I dumped in granular chlorine intermittently for 3 months or so.

Finally got around to changing the filter, and after draining the pool - bam. NO grout, and LOTS of lifting tiles. Here is a picture. dam_n. I myself went against everything that we preach here. Lol. I feel like that medical doctor who scolds his patients, but if you look closely, you can see his nicotine fingers!

Moral of the story - stay away from granular chlorine! Its not so painful for me to fix, as my guys are employees, but this could be a significant cost for any homeowner.

Guess you could have balanced ph with soda ash, but without pumps running you'd just have heaps of aggressive chems lying on the bottom...

Lesson learnt

Is the reason for that because ridiculous markup's are charged by Pool companies in Pattaya ?

Dear Doctor, I told you sand filters are nothing but trouble, throw it away and buy a simple cartridge filter, all plastic, no complicated valves, easy peasy lemon squeezy lasts 10 years easy.

Being a Doctor with a Phd in pools, perhaps you should have thought of using a temporary pump to keep the water moving. Go down to Global buy a 700 baht submersible pump and a 10m length of vacuum hose, chuck the pump in one end and attach the other end to the side of the pool. Aerate the water too.

I love the topic title, not to mention the one you have a warded yourself
