Griffo63 Posted April 22, 2021 Share Posted April 22, 2021 I need some recommendations of firms that can help unblock a waste water drain at my property. There is a septic tank - which is OK and a waste water "hole" where water from showers, washing up and the washing machine flows. The problem is when the washing machine runs the waste water backs up to the bathroom shower area. It eventually clears but can take up to 2 hours. I'm guessing the waste water drain must be blocked. I've tried local people but they don't seem to know any firm but I hoping some-one on this forum can suggest a suitable/local firm to help. My property is between Wanon Niwat and Akat Amnuai in Sakon Nakhon Province (75 k from Sakon Nakhon). Udon Thani and Kalasin are further away but in striking distance as is Nong Khai. Any recommendations would be gratefully received, thanks Link to comment Share on other sites More sharing options...
lopburi3 Posted April 22, 2021 Share Posted April 22, 2021 This in town or rural (in town likely goes into gray water drains on road so should be easy but rural may have a drain field that will have to be redone). If have normal French type drain system to street general workers can clean it out or septic tank pump truck can be used (but they will likely try to overcharge if commercial and off book charge if government).

My first action would be to bung some caustic drain cleaner chemical down the washing machine drain .With a bit of water to move it to wherever the blockage is, if you use the powdered stuff. Can buy the stuff at Tesco/BigC et al. Even the "mini" stores. Edited April 22, 2021 by VocalNeal 6 Link to comment Share on other sites More sharing options...

rwill Posted April 23, 2021 Share Posted April 23, 2021 If possible you could try putting a hose in the drain and use a towel or something to close the gap around it and try and blow out the blockage with water pressure. 1 Link to comment Share on other sites More sharing options...
ehs818 Posted April 23, 2021 Share Posted April 23, 2021 In my neighborhood there are trucks driving around that can refill your empty water tank if city water does not flow to you. You can have of of these people flush out your line for about 400-600 baht. If the blockage is simply between your toilet and the main line, use the snake method.

Not many have that kind of water pressure - but have seen them use air compressor - you don't want to be at the exit point when it clears. Link to comment Share on other sites More sharing options...
perconrad Posted April 23, 2021 Share Posted April 23, 2021 If you don't have a grease trap on the drain pipe from the kitchen sink then build one in to minimize the fat deposit which can block the drain pipe. https://www.lazada.co.th/products/flusso-ppib-15-grease-trap-tank-kerry-i552728429-s1008168091.html?spm=a2o4m.searchlist.list.17.54d130ddBpoJns&search=1 1 Link to comment Share on other sites More sharing options...

Pour several kettles of boiling water down the drain, you have to do quite a few to get the temperature up. If you have an electric shower unit, you can extend the hose down into the drain. The blockage will be an accumulation of fatty and soapy waste that has reduced the pipe diameter and will move if warmed up. What I would suggest to the P first is to run the washing machine on the highest temperature a couple of times first. Failing that, then try the hot water down the shower drain, the nearer you can get to the blockage the more effective the water will be. Link to comment Share on other sites More sharing options...
unblocktheplanet Posted April 23, 2021 Share Posted April 23, 2021 My bet is tree roots blocking the outside drain pipe. Depending how bad the blockage is <sometimes> this can be cleared if the exact location of the root can be identified & dug out. If it is an interior drain plug, pour a pot of boiling water down each drain once a week to keep clear. Usual advice: hair, mucous, Tonka toys, t.p.

AgMech Cowboy Posted April 23, 2021 Share Posted April 23, 2021 I grew up outside the 'city', which meant we had our own septic tank and gray water treatment. If a drain line started backing up (water in the shower and tube) after flushing or the washing machine discharging, we had to dig up the lines to find the blockage. Thank goodness for RotoRooter and the 'snake'. In most cases you'll be able to clear the blockage with the drain cleaning snake. (If not, start digging... ????) 1 Link to comment Share on other sites More sharing options...

Drain cleaning snake That might work, if not, a drain clearing nozzle on a pressure washer...... but it depends how many and how sharp are the bends in the pipe. I had a drain blocked by years of lazy incompetent builders etc washing cement residues into it. Caustic soda did nothing. Eventually I poured two gallons of acid toilet cleaner (15%HCl) into the drain and let it stand. It stood for about a week then began to go down slowly. Once I had a detectable flow rate, the pressure washer made short work of it! Fortunately the pipes are blue plastic an were not damaged by the acid. 1 Link to comment Share on other sites More sharing options...
DUNROAMIN Posted April 23, 2021 Share Posted April 23, 2021 Had the same problem myself, used the caustic soda flakes first time, that worked to free up the pipes, however about 3 months later had the same problem, tried the caustic soda and a snake, however, would not unblock. Traced the source of the problem back to the entry point of the sullage tank, this is where all the fat and grease had collected. Had to dig up the pipe about 1/2 M from the outlet. The pipe size was a 80mm, instead of trying to cut a whole section from the pipe I cut a inspection slot in the top of the pipe big enough to fit a 1/2 inch garden house with a 360 degree spray head, I managed to push the hose about 2M up the pipe and clean it out, the pipe for about 400mm was nearly solid with fat and grease, then merely cut an old piece of pipe to form a cover the old section and sealed it with silicone. This way I can re-visit the same area and have access to the problem area. I am now going to regularly pour some cleaner I bought from Global House down all the exit points in the house to help. Sorry to say, but better to do it yourself than let Thai back yard boys make a mess of your pipes. and charge you 'farang' price. Link to comment Share on other sites More sharing options...

Paul DS Posted April 23, 2021 Share Posted April 23, 2021 Oh dear, quite possibly a "blocked sock" from the washing machne. Sure try Caustic Soda, but quite possibly you will need a "professional" firm to air blast the pipe etc. Good luck! Link to comment Share on other sites More sharing options...

Let it sit for hours (i.e. overnight). Do not dilute with water. It may help dissolve the grease. If not, then it may be something else blocking the pipe; for example tree roots. In that case, you would need a drain cleaning snake. Edited April 23, 2021 by Gumballl Link to comment Share on other sites More sharing options...
