We are Pat and Nick owners of California Tiny House located in Fresno CA. When building tiny houses the first thing you notice is you are working with very limited space. Plumbing, especially the waste, always consumes most of the under counter space you have available.
Since using HepvO Waterless P-Trap not only the space required is reduced but the labor to add a P-trap and vent is eliminated.
We are an RV Certified builder and this HepvO drain is approved by the ANSI building codes. In short, we can highly recommend this product and have not had any problems since using it.
