autofill device is a big saver also for a few reasons. They add water only when needed then they shut off. This way you dont forget to turn your hose off. It also keeps your water level at the correct height so your pump isnt suckig air wich can be a sloww death to your system. Mechanical timer is agood way to reduce elec. use in half wich adds upto alot of savings. A basic inline clorinator mixes the clorine after filter tomaximize clorine efficency. I build custom pools in USA and we are really making them much more efficent than what I seen in DR. Filtration has alot todo with operational cost also,I use D E filters. Do they use them in DR
It is rare to see a DE filter in the DR. The reason i was told, is that because they are delicate, the people that normally maintain pools here would constantly be damaging them. Sand filters are the norm.
While it is true that you can destroy your pump if the pool is not filled properly and the pump runs dry, that has never been a problem for me in 10 years of filling the pool with a hose when needed. I have learned over time how much chlorine to add and don't have problems with that either.
Adding water only when needed is not really a huge deal here if you are referring to the cost of water. At least where I live, the water is not metered.
I can see how what you are suggesting could add a level of convenience and maybe even save money.
DonP does have a nice infinity pool will mine is simply finite.
