How to fix a leaking laundry trap?

kikirock

I’ve got a bit of a laundry nightmare happening and I’m hoping I could get some wise wisdom from the Bunnings community.

It’s no surprise, I need to hire a plumber, but I just don’t have the money to do that right now and need a quick (can be temp - but not as bad a below) fix.

Basically, the laundry sink was “fixed” by the previous owner with a can of Fanta and some glue. This obviously led to some pretty bad leaking. 
I ran through things I found in the garage and made a way for the sink to at least go over the top of the pipe coming up from the floor. 
With the open top on floor pipe the laundry smells pretty bad in the mornings. I’m just wanting to know exactly what parts I would need to get the laundry sink connected to the floor pipe and sealed shut! I can only find videos/instructions for pipe coming from the wall. Can someone please help me??

Hello @kikirock 

Thanks for sharing your question about your laundry sink connection. The plumbing item installed under your sink is known as a sink trap, one end has a screw end that connects to your plug and waste the other end has a compression fitting. If you were to take this apart the item that is currently attached to the end of your plumbing trap is not suppose to be there. It is suppose to be attached to the waste pipe, but the issue is that the pipe is just ever so slightly short and wont link up with the trap.

In order to extend the waste pipe, I suggest installing a Holman 50mm PVC DWV Straight Coupling. You'll need to cut the pipe along the middle and apply Protek 125ml Type N Blue Cement Solvent and then place the coupling in the middle of the join. Do not press the joins very hard as your objective is to extend the pipe so that it reaches the bottom of the sink trap. Please note that the glue grabs instantly and will not give you a second to adjust it, so make sure to do a test fit before you commit.

With the extension in place, the waste pipe should now reach the bottom of the trap. You just need to unscrew the bottom connection slide the waste pipe in and re-attach the compression screw to hold the pipe in place. If you feel that it is too involved, I suggest engaging the services of a handyperson or a plumber to extend and re-connect your plumbing.

Just a friendly note that all plumbing works must be accomplished by a licensed plumber for safety and compliance.
