I can easily remember all but two on the OP list. I also remember this

A what!? 'Tis a chip butty. Never could see the sense of it but many loved 'em.

If this is indeed what has happened then it would be very difficult to recover a submersible pump. It rarely happens but when it does you can say good by to your 21,000 baht pump.

I am curious to know how far down is the top of your water in the bore hole? Mine is a 51 metre depth with water always 3 metres from the top.

why is t.d.s, in capitals, Deleted?

Sounds about right. I use a surface water well almost exclusively. My bore hole water is way too hard so only used for emergency. My filter arrangement is 2x four foot sediment filters followed by a resin filter. Then I have a 20" 5 micron and a 20" 1 micron poly something filter. Water is then good enough for general house use. Drinking water is from an RO unit which makes the water germ free. Sediment and resin filters are backwashed every 3-4 months (or when I remember) and resin is rejuvenated at the same time. I use a <deleted> (total dissolved solids) meter to check water condition. The <deleted> meter is not expensive and is readily available on line.

Borehole pump choices are: 1) Jet pump 2) Submersible pump. The jet pump is a lot less costly and works fine. I use a 370 Watt Mitsubishi jet pump which is more than adequate.

Do you know how deep your bore hole is? Sand and sediment don't normally come from a deep bore hole. Of course it could be that your bore hole is not lined. Normally the top (up to) twelve metres or so would have a 6" blue pipe liner inside to stop soil etc. from falling into the water from the top and side walls. If you don't have this then I'm sure an enterprising builder would help you install one. Pumps don't normally come equipped with their own filters but you can get some nice carbon filled filters which will remove sediment enough for clean household water. These are the "go to" people for water treatment etc. https://www.duan-daw.com/category/16/ถังกรองน้ำ-สารกรองน้ำ

I had to read that headline twice. In my mind was a very rude idea. Sympathies to the family of the worker who lost his life.

Plus free drinks for the village. I'll be round for mine later

Just like at a buffet.

Looking at the results of the lab. report I would say high levels of precision are not so important. Any contaminants which have been picked up from sources other than the bore hole are listed in with the bore hole water. It does not matter if they are from the hole or minimally from the surrounding environment, the water is safe but a bit hard.

Quite right. It calls into question the legitimacy of the doctor especially when he is reported to have said double vaccinated people are immune. They are not. The vaccine only lasts a limited length of time which varies depending which vaccine is administered.

I don't know if this is good enough but for the price, failure is cheap. https://shopee.co.th/TF▶-4ml-Universal-Epoxy-Resin-AB-Glue-Strong-Adhesive-Repair-for-Glass-Ceramics-Plastic-i.105085744.2121494275?sp_atk=cecc2ca7-47bc-430e-a9d8-f1cea09c474d&xptdk=cecc2ca7-47bc-430e-a9d8-f1cea09c474d

Did you Blow or did you suck?

As Above Thaiwatsadu

Agreed. Hilti is the best choice for fixings and allied tools. They produce a 2 part epoxy formulated for this sort of work loaded into a twin tube syringe which mixes as it is forced out into the hole. Trynotodo Thaiwattsadu sell a version of it. Used the Hilti stuff many times when concrete was found to be too weak to support expanding bolts. The hole needs to be a bit larger than the threaded rod to allow enough epoxy to surround the thread completely. eg 6mm bolt and 7mm hole.

Oops. Didn't mean to offend you. My thoughts were regarding motor cyclists respect for other road users.

In the bathroom probably. Have a look around the floor, there may be another drain somewhere to allow accidental water overflow to have an escape route. These are generally inadequate as regards water traps.

What!? To get a motor bike license? Give over.

Yes any government hospital will know what is required for about 100 Bhat. As has been mentioned, it's just a few basic pulse, BP and eyesight tests. I was also given a colour blindness test which involved looking at a few cards with coloured spots and identifying the hidden number. You will get a signed, prepared letter which the land department will want.

What's your water like? Mine is hard as nails. Calcium from gypsum rock 51 metres down. I use a surface water well almost exclusively. The time when I switched over to the bore hole was for only a few months but the calcium damage was not nice.

Well yes. Equipment does fail from time to time but I note yours failed "safe" which is normally the default. I expect, when this happens again, you will check your isolator/CB before having companies dig holes to look for faults. With the exception of a Safe T Cut, I have had a few MCB devices fail but always they have failed open circuit which, whilst a nuisance, is not dangerous.

I understand intimately how much love insects have for rural, well lit homesteads.
