a high resolution photo of plumbers at a trade show standing inside a giant, sanitary, stainless steel drain pipe. There is a round drain grate above them. The walls and floor of the drainpipe are smooth with no openings. The plumbers are dressed in casual clothing. A "WATTS" booth representative with a blue shirt is pointing out features of the drain, like rounded corners, and seamless fittings so bacteria has nowhere to collect. There is a few small screens on the inside wall of the drain showing features and benefits. The plumbers are engaged and fascinated by the immersive experience.
