 Plunging a sewer trap
Author: felcunje

Hi,

Does anyone know what tool is best for plunging the sewer trap to a old
house. This is a house that has a pipe coming up in the front lawn. I
once had to call a plumber to plunge it and he used a tool that came in
3 foot sections and had a disc attachement on end. Does nayone know
what this tool is called, how much it costs and where it can be found?
I have asked at Home Depot/Home hardware etc and noone seems to know
what it is called or where I can get one.

I am in Toronto if this helps.

I have never heard of anything like that, but since it would probably be fairly expensive, and would be a waste of time an money, call a plumber do the job right, not plunge the drain.

I got a qutoe from a plumber and they said 1000.00 to remove the trap. I only have to plunge tjhe thing like twice a year and probably won't be here for more than 3, so I was hoping I could just get this 3 piece plunger.

YOu will probably have better luck with an expanding "bag" that hooks to the end of a hose and then slides down the pipe. It blows up when the water is turned on and seals to the pipe so the water has to go down the pipe, assuming you have it inserted all the way past any side openings.

I've got a couple of them. I made one for my wife to use at a property that used to be troublesome (have since replaced the house trap). I don't know what they're called and didn't find anything by googling it. But you could make one fairly easily. Cut a 4" disk out of an old car tire, figure a secure way to attach it to any convenient length of 1/2" galvanized pipe (and I do mean secure), and plunge away. Works like a champ. It will usually clear a house trap with one pop.

This may start a conversation about house traps, but they are required in dense urban areas, and they're there, and they stop up sometimes. When they begin to stop up on a regular basis it's time to start digging.

The only good housetrap is one that has been dug up, ripped out of the ground and thrown into the scrap metal bin! when allowed by the local code.

If you can't get rid of it the best way to clean it is to push a 3" round blade through the trap and back repeatedly with a power snake while running out a load of hot water out of a washing machine then take a wet/dry vac and suck all the water and remaining debris out of the bottom of the trap. The debris build up is quite hard and will stay where it is unless the blade scapes it loose.Plunging will only cure the clogging briefly before it happens again.

If you use a blow bag make sure it gets down into the trap past the inlet otherwise it will be pushing water into your house and overflowing the lowest fixture. COULD GET REAL UGLY!

Thanks for all of the replies guys. So when plunging the trap the plunger does not have to bend? As per steve_g's instructions I could just use a long plunger with a 4" disc on the end?

If thats what you want to frequently do go for it! If not remove the trap or get it properly cleaned for a much longer solution.

I Have heard of this tool as a plumber used it on my brothers house in New Jersey. It worked like a charm.I have never used one. There are no house traps here. I think you can make one. You described it pretty well.

And if the disc comes loose in the sewer, then prepare yourself to pay the $1,000 to dig it up because there may be no way to retrieve it without excavating.

That's why I said 'secure' twice. But the house traps around here are all 5" or 6"; only the vent is 4", so the disk - if it came off - would probably flow into the main.

If the riser is 4" and the trap is 5" or 6", then you are not plunging the trap, you are surging the water. To plunge something you need a good seal, and a 4" disc is not going to seal a 5 or 6 inch trap.

A better solution may be to modify a Closet Auger by either bending the tube straight or disassmbling the cable and handle cutting the bent end of the tube off and using a piece of 1/2" EMT Conduit and a steel EMT coupling to fasten it onto the end. Then use this to auger the trap. Its not the right way to do it but at least it will loosen some of the debris and make a larger opening than plunging. I myself would clean it properly, But since this thread seems to be so persistant on doing it a different way here's a better way.

A trap plunger uses the water in the 4" vent to push the blockage out of the trap. I've used it for regular customers as well as on my own properties and have found it to be a reliable solution - it clears the trap very easily and works 99% of the time. If the trap and/or building drain stop up repeatedly I replace it.

But if it were a stoppage in the trap itself wouldn't the 'pressure' being created from plunging the fresh air vent go towards the house instead of being fully directed to the house trap?

Unless of course ALL of the piping was holding water, which is usually the case when a house trap clogs up.

I think you're looking for a 4" Disc Curb Plunger. You can purchase the disc and it threads onto a 3/4 steel pipe. You can purchase the pipe at any hardware store I would assume and maybe get about an 8 foot length.

Here is a site that sells the disc:

Hope this helps
