Why shouldn’t I use a CLEARFLOW pump with scalding hot water?
A Clearflow may need to be used with very strong chemicals, such as neat hydrochloric acid, when being used for descaling. To enable this, all wetted parts are either plastic, or are sleeved in plastic, and this imposes a temperature limitation. At high temperatures the clear plastic flow and return hoses will become very flexible and may kink, so don’t put scalding water through them. High temperature resistant hoses can be fitted to a Clearflow pump – but this type of plastic is not transparent, and you’d loose the advantage of being able to monitor water cleanliness by viewing the water as it travels through the pipes. And last, but not least, working with scalding water poses risks to you!
