I am new to the forum, I've been post similar questions in other threads, but haven't really got the answer I asked for(I did get help tho). And It was my fault as I didn't ask the questions in clear way, either put the questions under the right thread. I guess I was just desperate to get the answer before i can digest all the information.
I think I should be right this time after reading non-stop, hopefully...............
I am coming to the stage where I have to replace pump, sand filter, and SWG at the same time if I could which is really a pain..... They all got issues going(mainly too old to work properly), and I prefer to buy the new one, rather than fixing them. I have read quiet few threads here about the size of pump & filter depending on the type, feature & volume of your pool.
Below are the considerations of choosing equipment
- Climate: Perth, Australia. Hot, Dry, and windy in Summer
- Backyard surrounding: Lots trees and Bamboo, Dry ground in Summer
- Pool feature: Non. We have 3 water jets, and 1 return through skimmer box.
- Usage: 0.5hr/day, 2~3days/week/summer, 0/winter
- electricity unit: US$0.21/kwh, and they are going to increase again soon
- equipment running time: 6hr/summer, 2~3hr/winter
According to the pool size(~60,000L), here is what i think it suits, and please do correct me if i am wrong:
1. Pump: 3/4hp or 1hp variable-speed. what do you think? is that suitable? Will that save the power bill? Or 1/2hp single speed would do the job? Will it be enough to do vacuuming?(inlet pipe is 50mm/2", from pool to pump; outlet pipe is 40mm/1.5" from pump through filter back to pool)
2. Filter: 28"~31", as we are getting a lots leafs and sand blowing into the pool. I really don't want to back wash very often as that's what we've been doing.
3. Media for fiter: Sand. Would anyone recommend Zeobrite? I read the thread dated back in 2011 and most of senior members wouldn't recommend it. Since it's 2014, any improvement? Or keep away from it?
4. SWG: Chlorine 50grm/hr. Will that be to much? Or under the conditions I have here, 50grm/hr is reasonalbe?
Since I don't have much choice regard to the equipment selection here in Australia, plus on a tight budget, can anyone recommend the brand here is reliable and the price is reasonable if you know any, much appreciated.
Thank you for providing such great place, I've learn a lot from the information that gathering from everyone to this website. And definitely knowing more than the pool shop I used to go. Thanks again for the effort that everybody puts in.
ps: whoever did the pipe configuration, created too many bends!! am i right?
