cheeryble Posted May 5, 2018 Share Posted May 5, 2018 hi I have a near neighbour down the river near Ban Tawai called me today. His toilet soil pipe has been getting more and more blocked. He says he has put NaOH down it several times. I said have you used a plunger with a full bowl and very vigorously.? He said he got a local chung in who did that. I said the only thing I could think was a spring type root rooter type thing. But I havent seen one of these for 4 inch soil pipe, only the title skinny ones for small diameters/ Anyone seen or have brainwave? A factor is this chap is very broke at the moment, even the 300 baht for the unsuccessful chung hurt. Link to comment Share on other sites More sharing options...
BEVUP Posted May 5, 2018 Share Posted May 5, 2018 4 " , sure about that A mth or so ago, the women across the rd had some extensions done The ensuite was designed to walk in with basin first then toilet then shower But I told her can't happen, " you have a 4 " pipe at the end near the wall & a 2" pipe before that ( meaning you would walk through the shower ) Her reply " oh no the 2" for toilet & 4" for shower 1 Link to comment Share on other sites More sharing options...

Bill97 Posted May 5, 2018 Share Posted May 5, 2018 4" is standard for toilets. The small diameter spring will work, it will open enough to start things moving. A hose sometimes provides enough pressure. Put it in the toilet as far as possible. Wrap a towel around the hose where the hose where it enters the toilet drain and hold the towel firmly down to seal the drain hole when you turn the water on. Put no paper down the toilet. Is it backing up from the septic tank or can the septic tank accept more input? Sent from my iPod touch using Thaivisa Connect 1 Link to comment Share on other sites More sharing options...
VocalNeal Posted May 5, 2018 Share Posted May 5, 2018 Maybe his septic system is full? Needs to call local government to come with a truck and suck it clean? Maybe a 9ft python is sleeping there. 1 Link to comment Share on other sites More sharing options...

Sent from my iPod touch using Thaivisa Connect Thanks I must ask more detail......i think he said water could be seen flowing into the tank but in that case it wouldn't be blocked.....maybe it was just a bitMust aso ask if he's got a round mop to wrap a carrier bag round and pump the WC outlet. I seem to remember in the distant past "fisting" the WC with a thick bin liner up my arm. Would i do it to someone else's? Hmmm Edited May 5, 2018 by cheeryble Link to comment Share on other sites More sharing options...
thaibeachlovers Posted May 5, 2018 Share Posted May 5, 2018 If using a plunger, has to be done very vigorously. Useless just putting it in and pushing the handle a bit. Usually caused by putting too much paper down. If not paper, probably a full tank. I'd try the hose pipe if the plunger doesn't work. I think a plunger can be bought for about 50 baht from a local hardware store. 1 Link to comment Share on other sites More sharing options...

cmsally Posted May 5, 2018 Share Posted May 5, 2018 The other one to check is the air ventilation pipe. If the air ventilation pipe is not clear, it will not flush. 1 Link to comment Share on other sites More sharing options...
worgeordie Posted May 6, 2018 Share Posted May 6, 2018 If this has just occured recently,It could be all the rain we have been having,the soil gets waterlogged,so the septic tank cannot drain the water. One thing I do is stand on a chair and pour a bucket of water in the bowl from a height,that might shift any blockage. regards worgeodie Link to comment Share on other sites More sharing options...
cheeryble Posted May 6, 2018 Author Share Posted May 6, 2018 I took a visit yesterday but it could only be a couple of minutes.I said did u pump the WC vigorously?Yes they Chung did he was a big guy.He took the lid off the cement ring septic tank.It was not high. I said looks like it’s draining ok.He said oh the guy pumped it out.......there's a leak in a supply pipe outside.The leak was slow but he said the tank was full before.So Worgeordie's water problem maybe.With the lid off the pipe from WC was exposed I said how does it dflow. He said it doesn’t....or barely...".so deffo this needs clearing.I noted that the cap on the lid was jammed on. This means air only getting outround the lid Rim Sally. But he said it’s been working fine for 8years.However very narrow air gap could mean he had a slow flush of the WC for those years which slowly caused a clog to build up. I will warn him about this. Just called and he had someone else arriving to have a go at it. Worgeordie could u send a photo of u on a chair pumping the WC?

eyecatcher Posted May 6, 2018 Share Posted May 6, 2018 (edited) a common problem are the old concrete ring soakway types. Very often the invert level of the incoming poo pipe is too low and soon the chambers fill causing a vacuum that makes you think the wc is blocked. first job is to check that. Also look at other small drains feeding into the same pipe like shower or basin, they could be clogged again creati g a vacuum. NaOh...big no no for me. A tiny amount is ok in a basin or shower but the danger her is the heat generated by NaOh is enough to melt the pipes or at least any solvent weld which heat up and become loose again. For a wc, a snake is still very difficult to use, the ones you buy at generally only 3m or 5m long and ramming what you think is a blockage maybe a pipe bend..be carefull. Lots of water and a plunger can move easier blockages but any thing serious you need the drain pros out and thats 2k a time. They also carry a proper 100mm snake, heavy duty powered by a genny but they wouldnt use that in a wc...more likely a vacuum plunger, pumped to pressure and released. Scare me to death to be honest becausd i dont trust joints bei g sealed properly. You can buy chemical cleaners at makro. The solution is heavier than water so it slowly sits behind the blockage eating it away. Very effective and safer Thats my two penneth anyway Edited May 6, 2018 by eyecatcher 2 Link to comment Share on other sites More sharing options...

poanoi Posted May 6, 2018 Share Posted May 6, 2018 caustic soda (soda fai) with large quantities of boiling hot water flushed down at high tempo is the best bet IMO, and, like a relative of mine used to say, a poo knife is good to have. for some reason, plumbing is often not done right in this country Link to comment Share on other sites More sharing options...

A large amount of NaOh and boiling water is going to create a volcano and give of a lot of poisonous gas. On the other hand if you dont have a lot of boiling water then all that Naoh will not dissolve and just sit at the bottom Creating another blockage Well upto you, when it doesnt work come back and I will advise on how to fit a new toilet and soilpipe Edited May 6, 2018 by eyecatcher Link to comment Share on other sites More sharing options...
cmsally Posted May 6, 2018 Share Posted May 6, 2018 I guess it really must be pretty blocked. Maybe just try getting a big bucket of water and pouring in all at once, that clears the majority of blockages. Link to comment Share on other sites More sharing options...

tifino Posted May 6, 2018 Share Posted May 6, 2018 Geez... not been done for 8 years! Septic flushes should be no more than 3 years apart... Do the workers have the luxury of a snake that incorporates a video link unit? There's probably some tree roots by now And a camera unit is good insurance in case of unknown bends.

kickstart Posted May 6, 2018 Share Posted May 6, 2018 If you can take the lid off the septic tank, can you push a hose pipe up the pipe and back flush it , if your water pressure is good it should work. Or if you have good access to the pipe from the septic tank get your local guy who empties tanks to use his pipe to suck the blockage out, the vacuum he has that should work, his pipe should be 3inch would fit your 4 inch pipe ,then he could empty the septic tank ,our local guy charges 300 baht. Re, NaOH I always mix it in a bucket first, then you do not any lumps. Link to comment Share on other sites More sharing options...
