    Trying to plant the full alphabet: Avocado, bananas, durian, kaffir lime, lemons, lychees, mangoes, rambutan, mangosteen, thai cherries, star apples, nectarines plus several other native Thai fruit trees. Then there's 160+ teak trees, 15 mahogany and another 15 Tropical hardwood trees. Plus Yuri...

    Water Pump and Watering System

    Taen the village boiler maker / heavy machinery mechanic came over this morning and methodically went through a fault finding & rectification process. Changed a coupling. Cleaned both threaded sections. Wound on copious turns of thread tape. Screwed it in to the pump housing: still too...

    Agree, the union thread is loose. Both threads were very clean. Permatex Thread Sealant looks a better option given how loose the thread is.

    Water Pump and Watering System

    This sums it up pretty well. The unions (nipples???) I've tried are, as you say Ferret, as loose as a bar girl's fanny. That's why I was so keen to use an O ring. At least it would seal the shoulder of the union against the pump housing.

    Water Pump and Watering System

    I must admit that crossed my mind earlier when @Rice recommended Permatex Pipe Sealing Compound. Rice was okay with it - see Page 2.

    Water Pump and Watering System

    Nothing wrong with the pump. It pumps like a thousand bastards when it's not sucking air. It's getting the union to seal into the female pump housing.

    Water Pump and Watering System

    Rice, unfortunately the Permatex joint compound you recommended hasn't done the job. It arrived yesterday morning after being ordered on-line (nil stock in Surin) and used to assemble the pipe union and pump inlet. I must admit I was dubious straight away due to the low viscosity of the...

    Water Pump and Watering System

    Rice, appreciate the info on Permatex - thanks. Will get some and give it a try as it's still sucking air although I'm not sure it's the union into the pump. May well be where I joined the inlet / suction lines between the pump and the dam. Or the coupling. Is Permatex okay to use on a cast...

    Will find out if my fix of thread tape and silastic works shortly - off to prime the pump and give it a test right now.

    Water Pump and Watering System

    Appreciate the follow up Ferret - thanks mate. Wasn't able to find an O ring in Surin with the right CS so I trimmed 3mm off the union (nipple???) then wound on plenty of thread tape before finishing with silastic around the joint. Now all I have to do is reinstall it without disturbing the...

    Caraboa beer

    Hi Cent, If she likes Tawandang, she may also like Thai Sato, which is made locally. It's only 4% and not too sweet. Available from Subtle Hub a great little craft beer bar located at 6 19 Rungkit Rd, Surin. Subtle Hub also have a great selection of their own craft beer along with other Thai...

    That's the problem Ferret. Plenty available with a smaller CS. So far haven't found any 5 mm CS. But will definitely do a cut and shut if I find one.

    Found a pkt of 5 X 65 mm OD 5 mm CS on Lazada out of China. Hoping I can get some locally instead of having to wait. O Ring

    O Ring Any thoughts of a quick fix to the pump inlet sucking air were tossed out the window when trying to find the right size O Ring in Surin and Chom Phra. Tried Thai Watsadu, Do Home and several pump repair shops in Surin but no one carries this size. Have yet to try Global House and Home...

    Water Pump and Watering System

    Mystery solved by the local heavy machinery / farm boilermaker whose workshop is across the road. He spotted the problem straight away. Where the nipple screws into the pump housing I should have fitted an O ring to seat the nipple properly against the pump housing and the shoulder of the...

    Water Pump and Watering System

    It is a simple impeller pump Rice. My diagram skills are pretty poor so a couple more photos may help: showing the suction and discharge pipes plus the primer. The foot valve is located approximately 28 metres from the pump, sitting 4 metres below the pump centre line. It normally works very...
