They have a bunch of overpriced Hanna meters of questionable accuracy. Along with regular OTO drop tests that are hard to read and become inaccurate with elevated Chlorine levels. They don't have anything to test CYA and Alkalinity in salt water.

Vinyl planks are known for outgassing phthalates. Different brands outgass different amounts - impossible to say how much without expensive lab testing.

Does that sign represent "quality" of water? ????

No proper test kits are available for sale in Thailand.

Never mind. Greenhouse cover plastic is thick enough to use in place of builders plastic - not as thick but should suffice.

Can you (or anyone else) please post a link to this product? I was searching around Lazada and HomePro but coudn't locate anything similar. All my searches have returned thin wrapping plastic, masking films or greenhouse covers. The greenhouse/shed cover is being the closest match.

Thank you for the info. Will ask my builder to follow your advice.

A layer of striped-blue plastic sheets? Instead of sand?

Yeah, the price difference is not significant between those two if you need a 3HP pump. btw, are you sure you need a 3HP one? If your pool is not huge then you might be overpaying for an oversized pump. A bigger than necessary pump would also be consuming more energy over the smaller one at the same running rpms. If you want to save on electricity by keeping the pump running 24/7 at the lowest possible speed then don't forget to make sure to determine the pump's lowest running rpm threshold where your SWG shuts itself down.

Emaux is a Chinese brand that is not marketed in western countries. It might be sold in Australia as a discounted brand. I think that being the reason for no reviews. Pentair IntelliFlo3 is obviously a much higher quality product compared to Emaux SPV or newer Emaux EPV. But it comes at a huge price premium. btw, what's the price difference? Is it 2 or 3 times more expensive? For basically the same efficiency.

Will speak to the builder tomorrow regarding my discovery ("missing" rod). Any suggestions on what to ask? It's a fairly large builder working on multiple houses at any given time. They've been pretty responsive to my concerns during the build. My house's been permitted and built according to regulations. I'm kind of confused now after reading @bluejets comments on the reasonable length of the rod. Yes, If rectifying on my own I would just follow his advice. But in this case it's still fully a responsibility of the builder - the house hasn't been fully finished yet. Now that I've discovered the problem on my own, should I make a "demand" for the Earth/Ground system to be installed according to Thai regulations (240cm) and not a cm less? How about the exothermic weld? Should I "demand" that the install is done 100% according to regulations? Asking since the rod omission is a bad case of negligence on their part.

A question for everyone... Are they really marked?

Thanks, I've mistyped. I've checked HomePro. The rode selection on their site is 30cm, 100cm, 180cm, 240cm and 300.

OK, I'll ask the builder to get a 180cm rod.

Thank you for the detailed write-up. I'll ask my builder to install a 180cm (8ft) copper-clad ground rod combined with a clamp.

And might turn out as the wrong direction in the end. Lots of long term unknowns. Continuous surface moisture effects on the paint layer under the hot Sun. Effects of multiple thermal expansion/contraction cycles on the wall's structural layer (if not sprayed continuously). Potential foundation over-saturation and related damage. Just to name a few...

Speaking of the electrical contractor... There was another electrical problem that has surfaced during the A/C install. I've hired a local electrician to verify the A/C guy's claim - the problem been confirmed and relayed to the builder. But apparently he didn't bother to check the Earth/Ground resistance. To be fair I've only asked him to look into the known problem that's been reported by the A/C installer.

Here's the reason for my question (in the picture). The contractor has "forgotten" to install an Earth/Ground rod. He's covered the wire with dirt and called it a day. I have found about it by accident while digging around the area, looking for other stuff. I'm not sure if I'm still on the builder's meter. Assuming PEA comes in for an inspection and does a half-decent check. Would they even be capable of finding such a problem, if not for the accidental discovery of my own? I guess they could do that by checking the Earth/Ground resistance.

Is there such a thing in Thailand? Is it required by law to get done for every new construction prior to sign off? At least for the permitted builds. And if there is, is it applicable everywhere or maybe just urban?

Take it back. "the paint can keep surfaces 19 degrees Fahrenheit cooler than their ambient surroundings at night." https://www.purdue.edu/newsroom/releases/2021/Q2/the-whitest-paint-is-here-and-its-the-coolest.-literally..html

Surely 3C above ambient?

Thanks for the link. Never heard of that battery tech before. It does sound like a very good value. Please keep us posted.

No one has commented on any special ventilation measure. Is it safe to assume then that batteries and other on the ground components are robust enough to reliably function at 40-50C ambient?

Yeah, but not really an option in this project due to the roof runoff management situation.
