Inderpland Posted April 14, 2020 Share Posted April 14, 2020 (edited) The pressure in the water mains is too weak to supply my tank and will remain so in the foreseeable future and paying 300 Baht for muddy water every 5 days is an inconvenient and unappealing option. I wonder about using and air driven ejector to suck the water from the mains into my tank and would like to ask if anyone has tried this possible(?) solution?

bankruatsteve Posted April 14, 2020 Share Posted April 14, 2020 You don't want to do that. It is most likely illegal even in Thailand and nasty things could happen. If the pressure is too low to fill your tank there is probably not going to be anything to suck anyway. You shouldn't have to buy muddy water though. What do your neighbors do? Does your village head offer any solution? Link to comment Share on other sites More sharing options...
metempsychotic Posted April 14, 2020 Share Posted April 14, 2020 Install a tank and a pump. Every house I have lived in in thailand has had this set up. Have the tank filled once and have mains feed keep tank full with a ball valve. 2 Link to comment Share on other sites More sharing options...
lopburi3 Posted April 14, 2020 Share Posted April 14, 2020 It most surely is illegal to pump from mains (was often done 30 years ago - a lot of soapy water to drink as other homes had hose in wash tubs). He said mains will not fill his tank so only real alternative other than buying would be to have tank underground so filling at ground level. An alternative would be making a sump and using a small pump to get into tank. Link to comment Share on other sites More sharing options...

Plastic wash tub or waste bin at (or even below if the pressure is that awful) ground level, filling from the mains, small submersible with a float switch to fill the main tank. Tub fills slowly from mains, level gets high enough submersible starts and runs until the wash tub is empty. Repeat. Link to comment Share on other sites More sharing options...

An alternative would be making a sump and using a small pump to get into tank. I used to have two composite/plastic(?) tanks buried underground but they both cracked so had to get an overground one again. The underground tanks were a much better solution as water flowed a lot more easily and often. As the ejector ideas apparently is illegal I'll modify the gutter to utilize what little rain there is to replenish the tank. Link to comment Share on other sites More sharing options...

The dangers are numerous, one being contamination of (or more) everyone’s water supply. 1 Link to comment Share on other sites More sharing options...

Well it may well be what he needs to keep enough water on hand to satisfy demand. Harvesring rain water is a good option, but he also needs to check consumption, low flow toilets and showers etc. Ultimately if there isnt enough water coming in he will need to import. Sucking water straight out of the mains could lead to a world of hurt for both him and his neighbors. 1 Link to comment Share on other sites More sharing options...

How big is your tank? I had a similar problem, I had a 1.5k litre tank and I was getting black dirty water, bought another 1000k litre tank and fit it. Drained the big tank and pressure washed it, full of algae. Then started buying water from the water bowser trucks, 2000L at a time. The only downside is that 2,500L was only lasting me about 6 or 7 days, but at only about 150baht for a load so it wasn't killing the bank.
