Looking at plumbing options on an Elos tank. The tank has their quiet drain system, one in each corner. Elos supplies the fittings to go into bottom of the tank and are barbed for soft pipes. Supplied is soft tubing for drain and return. Drain is 1.5 ID ribbed tubing and return is 1" ID smooth silicone. There is not enough tubing to make the long run so will need to combine with rigid PVC. Elos recommends the flex tubing for noise control. I want to add ball valves in case I need to shut off flow. Do I ditch the Elos recommendation and hard plum or use a combination of soft and hard piping? Any advise or thoughts from more experienced would be appreciated.
