I know that it is at a certain degree, the RO/DI will operate better. Meaning there are more water that can be process. since it is now winter, is there a way to increase the temperature of the incoming water without the risk of killing the membrance? like running hot water from the water heater ... Also, beside the garden faucet, is there another way to get a water source inside the gargage? dont want to make the lady mad by doing stuff in the house. And my laundy room is too small to leave the tubs in there.
