What you need is a recirculation pipe and diverter valve. Just closing the discharge valve will just drive the pressure up on the pump side. Half the flow needs to go back to the tank. Closing the suction side is much worse as it will cause cavitation and ruin the pump.
All of your options are energy inefficient. It would be better in the long run to buy a properly sized pump.
I made a model for our current build and the district engineer charged us about 10k to convert it to Auto-CAD construction drawings. It is going pretty well.
While I an generally unimpressed with her claim, I am less impressed with the safety layouts for road repairs. It is a real hazard for the workers. No cones, lights or warning signs in use. It is time someone addressed the issue.
The problem with reviews like this is that many are petty and vindictive by over entitled falangs. That was certainly the case in the famous Koh Chang incident a few years ago.
I have never had an issue with bad reviews, mostly because I usually try to make them constructive. Recognize underlying issues and efforts made. Usually service and hotels in Thailand are above their price point.
In these cases, how do they collect overseas? No Aussie court is going to enforce this.
Statins are largely interchangeable but they are not all the same dosage. If you are living here, go to the local government hospital and get on whatever the local choice is. It will be easier and much cheaper.
Easy for those of us that live here to criticize the falang tourists but it makes sense to me. We have the support to go everywhere either on our own or with Thai family. The outer trips are for later visits but it is expensive to visit frequently. I would happily take a holiday in Samui, even though the food is pretty lame,
Are the Russians in Phuket more annoying than the Indians in Pattaya or the Nigerians in Bangkok? The Thai touts and Tuk-Tuk scammers are a bigger problem everywhere.
What you are talking about is called visa fraud. It is illegal. Conspiracy to commit visa fraud is also illegal and this page should not be supporting it.
But you know the meaning of CD, DVD. SIM Card, SD-card, computer, streaming, Zoom, Skype and a host of other words that did not exist at the time. Selective ignorance cannot be used to justify bigotry.
