When should the Inta BO91077.1 be replaced?

Taps that leak or have a problem with temperature regulation will usually require a replacement Inta BO91077.1. Sometimes loud or rattling noises can be another indicator of a broken tap thermostatic cartridge.

• Good condition O-rings seal passing water in the cartridge. Worn-out O-rings give rise to leaks.
• The Inta tap should be able to smoothly manipulate water temperature with the turn of the handle. If the opposite happens, the BO91077.1 may have (or is about to) stopped functioning.
• If you hear noises every time the tap is in use, it might be a sign of an airlock (in gravity or pumped systems) or there is something wrong with the Inta BO91077.1 thermostatic cartridge.

In these three scenarios, replacing the BO91077.1 Inta thermostatic cartridge can fix the tap and get it running like new, like normal.
