Depending on the size of your studio and the requirements of your system this list will change but here are the basics going right from the bottom drain of the sink to the exit drain of the system.
Tools
Hack saw
Dremel Tool
PVC 1.5 inch
Elbows 3
Straight 2 ft
Bulk head unions 2
Threaded/female adaptors 2
One adjustable “p” trap
PVC primer and glue
Teflon tape
2 Plastic Bins
11/4 inch compression adaptor
First things first, measure and get an idea where your trap is going to go, the space you have and where your inlet and outlet need to be. Make some drawing and such before buying every plastic bin and picking the two that work.
Step two is to cut the holes needed in the sides of both bins and the tops of both containers. On the sides make the exits for the bulkhead union as close to the top as possible and the entrance through the lid on the opposite side of the bin. I cut my holes with a Zip bit for the dremel tool and a sanding drum to get them just big enough to slide the pipe in, this will cut down on smells coming from the bins.
Step three is to layout the system dry. Make sure everything fits and you have the parts you need. Cutting the pvc can be done with a hack saw but is easy with a mitre saw.
The fourth step is to prime and cement connect your non threaded pvc joints.
I used teflon tape to seal the threaded parts, the bulkhead union uses a rubber gasket to make the seal to the container. No need to glue or seal this joint.
The install of the trap is going to depend on where your outlet is going to be and how tight your cabinet is.
The Sink trap bins have been going now for a year and have done well. I have cleaned it once to check how much was collected and how much is getting past the trap. All looked pretty good the only stuff getting past is like Terra Sig. The capacity of the two bins looks like it could go two years before getting cleaned out with how I use my sink.
***update***
I have added a small bucket in my sink that has holes made 4 inches or so above the bottom I pour and wash everything into this bucket. it allows for a slower trickle of water through the system to prevent washing stuff out of the buns with big flush of water.
Doing this! Thanks!
Very effective way to build a \”sink trap\” avoiding clay clogging the drain.
This is great! Thank you for posting it! I’m putting this together this week. Do you add bleach in the bins for the smell or is it sealed enough with the lids?
Why do you need the second small bucket? Isn’t one enough for all the clay and glaze to settle into?
