This is the genuine Bosta replacement drain plug (spare part No. 10) for the Counter Current System Type STP. It seals the drain port on the pump housing, preventing leaks during normal operation and allowing controlled drainage during servicing or winterisation. Keeping this plug in good condition is essential for maintaining a watertight, properly functioning counter-current system.<\/p>\n
Designed specifically as a factory spare part for the Bosta Counter Current System Type STP series. Always verify your system model and the part number (No. 10) in your STP exploded-view diagram or spare parts list before ordering, as drain plug dimensions vary between counter-current system models.<\/p>\n
As an original Bosta spare part, this drain plug is manufactured to the exact tolerances of the STP pump housing. A genuine replacement ensures a reliable, leak-free seal \u2014 avoiding the risks of ill-fitting aftermarket parts that can cause water ingress, premature wear, or voiding of your equipment warranty.<\/p>\n
Fitting the drain plug is a straightforward task: remove the old or damaged plug from the drain port, inspect the seating for debris or damage, and hand-tighten the new plug securely into place. For systems under pressure or installed below the waterline, it is advisable to have a qualified pool technician carry out the replacement to avoid uncontrolled water release.<\/p>","protected":false},"excerpt":{"rendered":"
