This may sound off topic, but thought leave it here anyway. My business involves selling Android TV boxes, and lately there are quite a new Chinese sellers on Ebay and Lazada etc who offer the latest boxes at dump prices. Coincidental, they also are all registered as auto part stores

My leak got fixed, it was the first pipe elbow about 50cm from the skimmer that had cracked. Pretty strange since it is class 13.5 Upvc. Probably a manufacturer fault in the part. I now also discovered that the pipe from skimmer to pump doesn't go under concrete. They laid it at the other side...

Yes I know them, as I have dealt with them previously. The company is run by a foreigner, who charges prices similar to what you would pay in the west. Take note, in Thailand the foreigner is not allowed to work, and a Thai technician earns about 50 US$ a day. They are located 600 km from where...

After watching your video I now better understand why you insist on the pressure test. The only issue here is to find the equipment for that, and then I think particularly on the listening device.

I have a borehole to provide water to the house, irrigation system and pool, because I have no city water. :) Since the borehole pump hangs at 35 meter depth, and runs dry after 10 minutes, indicates to me that there is no water under the pool which is 1.5 meter in the ground.. I'm well aware...

Not sure if I'm misunderstanding this. The borehole is on a timer, because after 10 minutes it runs dry, which indicates the groundwater level is very low, which I thought is a positive in my case. The timer then stops the pump for 30 minutes, after which there is enough water to pump 10...

Since I can't find the leak location, I consider emptying my pool indefinitely. I have a 6 x 11 meter inground pool, and it is more a burden than it is an enjoyment. The house with pool was built 15 years ago, but I very rarely use the pool, and I'm single. At the same time it has to be...

But if the leak was not at the suction side I definitely would see water in the pump house, not? From where the skimmer line enters the pump house through the tiled floor, to the pump is about 2 meters of pipe in total, and everything is powder dry

All equipment is above water level

As explained in the OP, when I close the skimmer ball valve in the pump house, there is no water loss with the pump not operative. So what is the difference with the check valve?

There are no air bubbles visible under the pump cover. My Hayward filter doesn't have an air purge valve, but my chlorinator cell housing is clear plastic, so if there is air in the filter, the cell housing will have an air pocket as soon as I switch off the pump. This is not the case. This is...

There definitely is a leak. 2" of water disappearing over 24 hours isn't evaporation. My current question is why there is no water loss when the pump is running.

Which segment you have in mind? I certainly don't have the equipment to pressure test the piping, which is also almost completely covered by concrete. Definitely there is no leak in the pump house, I can eyeball that easily. Can you explain to me what my latest test mean? With pump on, no water...

I topped up the pool, then let the pump run for 4 hours, drawing water from the skimmer only. There was no visible water loss. Is this good news or bad?

Thanks for your reply, but not sure if I understand your question correctly. Maybe I need more morning coffee. :) Is return side the side of the skimmer or the side of the pump/valve? The valve is inside a tiled pump house, in the middle of a 1-meter vertical pipe. The top of the pipe is a...
