Sir, are these the chemicals needed to flush a borehole? Mine have wasted two submersible already by packing in sand. I've been told to do flushing but I've been foot dragging but with this info, I'm willing to give it a try myself. I'd appreciate your response sir. Thank you greatly

Yours need a thorough flushing and blowing...I don't know how many feet though but if its less than 300ft, then you need to do In-flushing,once the sand starts popping up from inside or outside the casing, then you gravel pack the hole( ½inch stone gravel)...Remember they must expose the hole...Wish u all the best...Chemical isn't necessary for yours for now..flushing first

I am facing this exact same issue right now, please let me know how you resolved it.

They drilled borehole for me last week but since that day till now each time I pump water, after few minutes the water will stop to flow. I have complained to the driller and he told me that the screen has not fully open. Has anybody witness such thing before. Should I ask him to come and change the screen?

The same thing happened to me, after some back and forth the driller told me that the borehole is not yielding enough. So I pump for 20 minutes and leave it for two hours before pumping for 20 minutes again. I had to sit down and observe before deducing that I have to pump for the 20 minutes yours might be different.
