The lower sleeve slots over the body of the Inta Zero anti-freeze valve and is sealed into the insulation jacket using Primary Pro Bond \u0026amp; Seal, integrating it cleanly into the insulated assembly and preventing water from tracking down into the insulation or valve body. The covered vent cap is then push-fitted over the top of the lower sleeve using a secure O-ring seal, enclosing and protecting the valve's anti-vacuum vent from external contamination.\u003c\/p\u003e\n\u003cp style=\"font-size: 14px;\"\u003eThe anti-vacuum vent on the Inta Zero valve must remain unobstructed at all times to allow the valve to function correctly — if the vent is blocked by debris or water, the valve may not discharge properly when the water temperature reaches 3°C. The ZEROGUARD's covered vent design keeps debris, insects, and water spray away from the vent opening, while the push-fit O-ring cap can be removed quickly by hand for annual inspection and cleaning without any tools.\u003c\/p\u003e\n\u003cdiv style=\"background: #f0faf9; border-left: 4px solid #008377CF; padding: 12px 16px; margin: 20px 0; font-size: 14px; border-radius: 0 4px 4px 0;\"\u003e\n\u003cstrong style=\"color: #008377cf;\"\u003eIntatec Installation Guidance:\u003c\/strong\u003e Where Inta Zero valves are insulated, Intatec recommend using the ZEROGUARD anti-vacuum cover to protect the valve's anti-vacuum vent.

font-size: 14px;\"\u003eThe Inta Zero valve's anti-vacuum vent allows the valve to discharge water correctly when the circuit water temperature drops to 3°C. If the vent becomes blocked by debris, insect nesting, or water ingress, the valve may be prevented from opening or may not discharge at the correct rate — potentially allowing the heat pump circuit to freeze. The ZEROGUARD protects the vent from blockage while maintaining the airflow the vent requires to function.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 16px; border-left: 3px solid #008377CF; padding-left: 14px;\"\u003e\n\u003cp style=\"font-weight: bold; color: #008377cf; margin-bottom: 4px;\"\u003eIs the ZEROGUARD mandatory or just recommended?\u003c\/p\u003e\n\u003cp style=\"margin: 0; font-size: 14px;\"\u003eIntatec recommend the ZEROGUARD for all insulated Zero valve installations and include it as standard in their Professional Installer Pack range. While it is described as a recommendation rather than a hard requirement, fitting it is considered best practice and aligns with Intatec's guidance. Given that the anti-vacuum vent must be kept clear at all times, the ZEROGUARD is the most practical way to ensure this on an external installation subject to weathering, debris, and wildlife.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 16px; border-left: 3px solid #008377CF; padding-left: 14px;\"\u003e\n\u003cp style=\"font-weight: bold; color: #008377cf; margin-bottom: 4px;\"\u003eCan the ZEROGUARD be removed for servicing without disturbing the insulation?\u003c\/p\u003e\n\u003cp style=\"margin: 0; font-size: 14px;\"\u003eYes. The covered vent cap is a push-fit O-ring seal and can be removed by hand without tools, giving access to the anti-vacuum vent for inspection and cleaning at the annual service. The lower sleeve remains sealed into the insulation and does not need to be removed for routine inspection. Only the vent cap needs to come off, and it refits by pushing it back onto the lower sleeve.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 16px; border-left: 3px solid #008377CF; padding-left: 14px;\"\u003e\n\u003cp style=\"font-weight: bold; color: #008377cf; margin-bottom: 4px;\"\u003eHow many ZEROGUARDs do I need for a standard heat pump installation?\u003c\/p\u003e\n\u003cp style=\"margin: 0; font-size: 14px;\"\u003eA standard external ASHP installation has two anti-freeze valves — one on the flow pipe and one on the return pipe. You therefore need two ZEROGUARDs. The Barco Zero Heat Pump Installer Packs (28mm and 1-1\/4\" swivel) both include two ZEROGUARDs as part of the pack. If you are purchasing Zero valves individually, order one ZEROGUARD per valve.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 16px; border-left: 3px solid #008377CF; padding-left: 14px;\"\u003e\n\u003cp style=\"font-weight: bold; color: #008377cf; margin-bottom: 4px;\"\u003eDoes the ZEROGUARD need to be sealed with Bond \u0026amp; Seal?\u003c\/p\u003e\n\u003cp style=\"margin: 0; font-size: 14px;\"\u003eThe lower sleeve of the ZEROGUARD is sealed into the insulation jacket using Primary Pro Bond \u0026amp; Seal (AS001) when the valve insulation is fitted, to create a weatherproof seal around the base of the protector. The vent cap itself does not require sealant — it relies on the push-fit O-ring for its seal. Bond \u0026amp; Seal 290ml (AS001) is included in both Barco Zero Installer Packs and is also available separately.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background: #008377CF; color: #fff; padding: 16px 20px; border-radius: 4px; margin-top: 32px; font-size: 14px; line-height: 1.9;\"\u003e\n\u003cstrong\u003eRelated Products:\u003c\/strong\u003e\u003cbr\u003eIntatec 28mm Zero Heat Pump Installer Pack (ZERO28 + AS32 + ZEROGUARD + AS001) | Intatec 1-1\/4\" Zero Heat Pump Installer Pack (ZERO14SW + AS32 + ZEROGUARD + AS001) | Primary Pro AS32 Insulation Shell (28mm \/ 1\" valve) | Primary Pro AS52 Insulation Shell (35mm \/ 1-1\/4\" valve) | Primary Pro Bond \u0026amp; Seal 290ml (AS001)\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Inta","offers":[{"title":"Default Title","offer_id":63832577409373,"sku":"ZEROGUARD","price":13.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/2051\/3629\/files\/IntatecZEROGUARDAnti-FreezeValveProtectorforIntaZeroHeatPumpValves.png?v=1773399625","url":"https:\/\/qualityheating.co.uk\/products\/intatec-zeroguard-anti-freeze-valve-protector-for-inta-zero-heat-pump-valves","provider":"AIZO Quality Heating","version":"1.0","type":"link"}
