You pull it before removing the wet end for a mechanical seal or impeller job, and in frost-prone areas at the end of the season so trapped water cannot freeze and split the pump body. A cracked body from a hard frost is not a warranty claim — it is the single most avoidable pump failure we see.\u003c\/p\u003e\n\u003ch3\u003eWhen To Replace\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThe plug weeps or drips when the pump is running\u003c\/li\u003e\n\u003cli\u003eThe o-ring has gone hard, flat or cracked and no longer seals\u003c\/li\u003e\n\u003cli\u003eThe square drive or hex head has rounded off\u003c\/li\u003e\n\u003cli\u003eThe thread has been cross-threaded or stripped\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitting Notes\u003c\/h3\u003e\n\u003cp\u003eHand-tighten only. The plug seals on its o-ring, not on thread interference, so winding it down hard achieves nothing except splitting the boss. Lightly grease the o-ring with a silicone-based lubricant — never petroleum grease, which swells and destroys the elastomer. If the pump is drawing air and will not prime, a dry or perished drain plug o-ring is a prime suspect alongside the lid seal.\u003c\/p\u003e\n\u003ch3\u003eRelated Parts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e78103\u003c\/strong\u003e — drain plug and air bleed o-ring on its own (\u003ca href=\"\/products\/o-ring-drain-plug-air-bleed\"\u003ebuy here\u003c\/a\u003e)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSP40089\u003c\/strong\u003e — complete lid assembly (\u003ca href=\"\/products\/complete-lid-assembly-for-astralpool-hurlcon-pumps-ctx-cx-tx-e-viron-xt-also-aquatight\"\u003ebuy here\u003c\/a\u003e)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSP40031\u003c\/strong\u003e — volute \/ wet end, MkII (\u003ca href=\"\/products\/volute-3-viron-ctx-e-series\"\u003ebuy here\u003c\/a\u003e)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFits These Pumps\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAstralpool CTX — CTX 180, 280, 360, 400, 500 (including MkII)\u003c\/li\u003e\n\u003cli\u003eAstralpool E-Series — E 140, E 170, E 230\u003c\/li\u003e\n\u003cli\u003eAstralpool Viron XT — P320 XT, P520 XT\u003c\/li\u003e\n\u003cli\u003eAstralpool XP range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eCommon search terms: Astralpool SP1116792, 1116792 drain plug, CTX pump drain plug, Astral pump drain bung and o-ring, Viron XT drain plug.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eManufacturer Catalogues, Diagrams \u0026amp; Part Numbers\u003c\/h3\u003e\n\u003cp\u003eNeed exploded views, spare part numbers, product numbers or diagrams?
