Where to buy PVC piping for DIY (drainage/WC system)

[craftsman]

ok... Some updates on the overflow DIY... That means its successful on tests....

I cut the PVC pipes to length and joined them together to form a "Double U" overflow pipe. Here it is assembled. Credit card for scale.

The pipes are 15mm and 32mm respectively.


I rigged up a 2 pail test environment.


The bottom pail has a Resun pump with an advertised flow rate of 660 l/h. It pumps the water up to the pail on the chair, and the overflow pipe siphons out the water back to the pail below. I ran the pump and overflow for 10 minutes before stopping the pump. Restarted the pump again after awhile, and the overflow pipe maintained the siphon.

I realised the overflow (38mm pipe) was placed a little too high, and have brought it down further to a more comfortable level.


Overall, I'm pretty happy with this. I'm done with the overflow system, and will now move on to the drip system from the storage tank. Hmmm... how am I gonna do that?

Glued joints are permanent. If you need to modify the piping system, cut and join with a short length of fitting rubber hose for passive pressure (as in drain outlet) or union connector, if pressurized.
