I have a dental clinic at first floor in delhi under construction.
Due to few reasons we are installing a water tank (300-500 lt) inside the clinic at 11 feet height. While, the chairs would be 14 feet and 30 feet (floor measurement) away from water tank.
I'm afraid, that due to small diameter of dental chair water tubing, the pressure at watercup filler and spitoon in dental chair would be too less.
I've gone through your answers regarding this problem related questions like hydro pneumatic system, or increasing the diameter of outlet pipe, or increasing the level of overflow pipe,but can this be applied considering the narrow diameter of dental chair tubing (2-3mm)
