Had an RO under-the-counter water filtration system installed and want to test the drinking water, and also the unfiltered tap water, which is "City" water.
The wife has made some attempts but couldn't get good information.
Where does one go in Udon to pay for some simple water testing--not well water.
Thanks in advance.

Talk to the local orbotor. Probably a free service.
Potamoi will know the finer details (and yes, that's his stage name, not potomai).

Costs about 6500 THB if my memory serves (my wife usually has to deliver and pay for the Health department witnessed samples once a year as part of the annual audit from our small water factory in Nong Khai).
The reports look like the attachments:
For home testing one can buy a TDS tester for a quick understanding if the filter is sort of doing its job. TDS is Total Dissolved Solids which is a broad indicator of filter wear (not so much water quality). Here are a couple of tools homeowners can buy for cheap:

NOTE: pH need about 15 min soak time for a more accurate test.

TDS testing of the city tap water before the under the sink RO unit then after it should give you an indication of the filtering capabilities. Flow reduction is another indicator over time. Measure the liters per min when the system is new then again monthly would be one more indicator.
The RO system should be backwashed at least monthly and filters changed +/- annually (depending on usage). There should b a little valve the installer should show you on how and when to backflush the membrane and filters.
RO systems are best designed with UV-C lamp after the filtration as well. These bulbs need to be changed +/- annually.
Then there is your main tank and lines which should shock treated with chlorine periodically.

There was a recent occurrence contaminated tap water in Udon near the Lotus's at Nong Khai intersection. If the water smells or is discolored consider other sources for shower and teeth brushing and certainly drinking.
