  1. the pump motor nominal power in label is 300w. pressure switch spec for wp-305 is 2.4 start and 3.0 stop, and this is how my neighbor new pump actually works. as said, few years ago I actually tested how much pressure the pump can do, and as result set the cut off to about 3.5. I recall he pump itself can make close to 4 however not obviously with any meaniful flow. With small flow like house tap or shower, it keeps at 3+ But it is obvious that the power motor takes within the switch start-stop range is way more than the 'nominal' - I guess the motor nominal power is defined in state when pump just moves water from inlet to outlet without having any (or at least much) pressure. Maybe can test some day out of curiosity
  2. Took off the cowling and fan to check - it is good, no damage and solid in place. Also, pump/motor rotates easily, only minor friction from seal, no bearing sound/feeling, no issues there. Measured the current of my pump and also measured my neighbor's pump current (same model but newer). I guess I am getting to the tails of the issue. When water flow is low, just below pressure switch cutting off, my pump runs around 2.8-2.9 amps. Same test for my neighbor shows about 2.4-2.5 amps, i.e both about double the 'nominal' level. It appears the nominal value indeed is just nominal, basically pump running without much load, just pumping water out with low pressure and no load for motor to pump against pressure. What is different between my pump as my neighbor's pump though is that I have tuned the pressure switch a bit, basically adjusted the cut-off closer to the max level that the pump can make (to get higher pressure to 3rd floor). I think the std cut-off is 3bar, mine is around 3.5 according to the gauge I have. When tuning it, I recall the pump was able to make close to 4bar, however obviously needed to work hard to get there, so set a bit down from max level. Now, when using my long 1/2 inch garden hose, with or without the sprayer, the pressure remains in 3+ bar range, keeping the pump running at 2+ times current vs the nominal level. I believe this is the explanation for the heating - the motor is simply not designed to run extended times at this load level, and the thermal protection just cuts it off if used like that. The pump does it job OK to deliver water at 3+ bar load level for normal household use though, no cutoffs from that use as usage times are normally fairly short. So I guess nothing can do, it is what it is. Would be interesting to hear if someone is actually using this pump model with long run times at low pressure level without the thermal tripping - or alternatively having the same behavior as I have with higher pressure and extended runtime
  3. Underground tank. The pump actually is cool even when the thermal will trip and stop the motor, only motor is hot. Pump has only weak thermal connection to the motor and thus dont cool the motor much.
  4. Good point, need to check that. That could explain.
  5. Usually using the rotation-adjustable sprayer. Pressure probably remains close to the 3bar cut limit as flow is relatively small. But I recall the heating also happened without the sprayer, just using 1/2 inch garden house with open end
  6. Pump is being supplied from tank, without any direct connection to city water. Tank is filled from city water. No air in system. Connection is properly done, that is not the issue.
  7. I have about 10yrs old Mitsu WP-305 water pump that has been working good feeding water to my house with fairly limited on-time as pump only runs when water used in te house. Due to reduced city water pressure, I have lately I used water supplied by the pump also for watering plants, and noticed that after a while (5-10min or so) of continuous running, the pump stops. It appears that this is due to motor heat protection stopping it. After waiting a while it just starts on its own, and faster if cool it by spraying water on it. The motor actually gets fairly hot, though not sure what exactly the temp is but feels pretty hot by fingers, thus I would guess the temp sensor that cuts the power works at about right temp In my neighbors garden have similar type of pump, though smaller size, used for watering the garden, sometimes running for hours without cutting. And that has the plastic cover on top, limiting airflow Pump does not have the plastic over on rather is in a ventilated cabinet with decent space for air. The fan at the end of the motor is ok, though the airflow produced by it is fairly weak. Turning it from the fan it rotates without any big force, though has some friction (guess due to sealing) and does not run freely like a standalone motor would. Anyone else experienced the same with similar pump? Any idea why like that and especially anything that could be done to keep it running?

    Home water pump

    For the usual house water pump (like my Mitsubishi WP-305), water for sure flows thru if the water in tank is higher than the outlet of the pump (or if supply pressure is higher than the outlet pressure). If the motor is not running, the pump simply acts as check valve (one directional valve). Water will not flow in reverse direction even if pressure in outlets side is higher than supply side (i.e water fill not flow from 3rd floor of your house to underground tank even if pump is off). The actual valve element and load spring is under the cap on suction side. Actually, if city water pressure is high enough, the pump will not even turn on when you use water in the house (as long as the pressure does not drop below the pressure switch threshold). Where I live, used to be like that at times until couple of years ago (pressure sometimes 4-5bars), though seems the pressure level in the system has been reduced to around 2bars so that pump always kicks in if use water nowadays Then it is a separate question where and why the water flows, esp if it should not flow. If all taps closed on pressure side and water still flowing, there is a leak somewhere. But pump works as it should
  9. If you live in developed world and use pirated content esp torrents, use VPN to hide your ip and avoid lawyers going after you
  10. Which countries you have found to work best for this purpose?
  11. ... Okay... So for a single farang without any other local income than interest on local bank account, the filing limit is?
  12. Have a walk around the Arab bars in the area behind marine Plaza hotel. After just walking around all farang focused bars in Pattaya are quiet! And I doubt they serve Guinness, possibly under the counter.
  13. As some posters have said on the thread, no need to file tax return if no income even if you tax resident. Some say the threshold is 120k, some say 60k, not sure what is correct. And the announced new regulation does not say anything about changing the threshold for tax return filing as far as I understand. Then the other issue is whether having or not having a tax ID makes any difference for likelyhood of possible audit if no filing. I never filed so far as no taxable income but got my tax ID last year, not for filing tax return, but was required by US bank. But yes, I will also join the 179 day camp if taxes become real and meanhingful, however the current announcement does not look like that necessarily being the case.
  14. That's obviously good for you if you can use that to make taxes paid to UK to credit against the income you would send to Thailand and assessed to be taxable income here. Likely your taxes paid to UK are more than what the tax here is anyway. Fortunately or unfortunately - depending on the point of view - that is not the case for some of us who do not need to file tax return anywhere (until possibly to Thailand in 2026) and would need to use transaction statements to explain where the income is coming from.
  15. Okay... This clarifies one issue. Profits realised by end of 2023 are not taxable, even if realised in 2023 and sent to thailand in 2024 - which is a good thing. However if you own anything that has appreciated since purchase (eg bitcoin, stock, fund etc) and you don't sell it by 31dec23 rather after, the whole appreciation is taxable if you send it to thailand.
  16. I recall another poster telling he had found similar studios on walking street, with similar moves. Several of them actually, though no windows, had to go inside the curtain doors to observe the moves. He gone there after hearing lobsters available in seafood restaurants, but also found out them overpriced - just like the meat moving around the poles. But beer was presumably cheap so at the end he was not too disappointed.
  17. Where did you read such definition? In your understanding, a bitcoin I held since 5 years ago, and convert to thb at hefty profit in thb terms in 2024 (but with a thb value less than in Dec 31 2023) is not taxable for the thb profit as it is just 2023 money that I convert to some other currency? Currency trade profits are not taxable income?
  18. Not targeted for westerners for sure. Who with sane mind would trust thai govt promised insurance with very low coverage so that they would decide not to take their own insurance? Oh maybe some Indians and Chinese
  19. Lately smugglers have been into pork smuggling. Alcohol, cigarettes, drugs, fuels and even luxury cars in the past. Human legs maybe the new growth area for smugglers.
  20. Looks like two rubbers for extra safety! If you send enough this year to cover for expenses for next year, no need to limit stay next year as it is not about global tax liability, only to what is sent here. Nothing sent, no issue
  21. To me depends on bank. If I send to Bangkok bank, it is usually next day at 2pm when funds land my account. If I send to krungsri, it is 1-3 minutes from click the send. I guess this is due to bkk bank being their local partner for the actual forex trade (visible as overseas source in bank book) whereas krungsri is just a local transfer.
  22. that's where the answers to my scenarios become relevant for some people, though probably majority of new condo buying farangs are not tax residents (yet), so the issue not relevant for them but for some people (like me) who have investments for couple of decades without tax on earnings, you could interprete the announcement also so that all earnings on top of the original seed investment 20-some years ago could be considered taxable income. thus the guidelines for definitions and rules is kind of important for some people, though maybe not majority
  23. well, depends on how and where your funds in your bank account have come. If they are non-taxable during current tax policies, they will not be taxed based on this change. but yes if the funds are taxable income sent to thailand during the year they were earned, they are taxable income in the tax year they are sent here. If you have not reported that income as taxable in the past even if you should have, you have violated tax law. but that is kind of outside of the scope of this thread which is about the announced change for 2024
  24. ...fortunately or unfortunately, most of the expats stayed here, it was the tourists that were missing - even if all expats would be gone, you would not notice it if tourist numbers back up as the tourists are not impacted at all by any income tax laws...
