We keep is as basic, simple, and chemical free as we possibly can. We use a marine grade adhesive sealant designed for underwater application. This allows for constant water submerison without the chance of shrinkage and chemicals leaching into the water. After all we are plunging for health related reasons. The more chemicals, epoxys, solvents, phthalates, and isocyanates you put into the Plunge you are also running the risk of exposure to your skin, body, and organs.
We completely seal the unit so there is no need to change seals, or chance the risk of unwanted leaks due to component failure. All accesores, pumps, filters, tubing are draped over the edge of the plunge above the waterline to assure no chance of dripping or siphoning, or unwanted leaking.
