Johnra... PM "Creative1"... a member here... he's an expert concrete/cement worker... and waterproofer... he might be able to help...

On first thought - can I have that tank in your avitar? I could really solve the problem. LOL

Yes, I too have thought of drilling the 1/2 out because I think it is too small for a drain. All of my other plumbing is 3/4. The flange shounds like a good idea. Would real epoxy do the job and seal the leak?

My only problem with more cement is weight. I don't trust the strength of the irons in the bottom. Two 1/8" rods at a 45 degree to each other. Maybe ok if I just mix up cement with waterprofing and render the whole inside of the GB including the floor and cover the flange with a good coating.

An expert who is not Thai - wow, sounds good. I will pm him tonight. Thank you Ruperto

When i built my system I render the pond 3 times, render, pump water in, leak, pump water out and so on.
You are almost finish John.

Ruperto, I did PM Ceative. I have not yet received an answer. He may be busy. Johnra

I have raised the GBs/cement rings up to 3 bricks in heigth. Approximately 30 cms. Now I am sure to have enought heigth for the GBs to drain well. I have also decided to drill out the old drain/or just made another one since this one is easy to close off by screwing in a plastic plug. I will then up the size of the drain to one inch since I read in many places that the drain should be larger than the incomming water line. All time consuming and I still need to know how to seal PVC pipe going thru cement so that it does not leak.

At present I am getting my weeping beds and raised, dirt beds back in production. I had almost destroyed all of my gardens when we cut the big trees out. I planted nothing for the last six months - not good. I also did more landscaping and work on the large pond to be. To much work spread out too much for one old man and one part time helper. Anyway very soon AP will be worked on full time until running again.

You should be able to get everything you need in either Global House or Home Pro. Have a good look around and don't accept "Mai Mee" for an answer from the staff (most of them have no f$%^*cking clue about what they have). Only talk to the manager to not waste your time. Isaan is indeed a ........ challenge for a falang. There are many ways to seal PVC pipes in concrete. Just google around a bit and you will get more answers than you can digest. Chok Dee!
