It should be positioned where the hose run can be secured properly and where the air valve remains accessible for pressure checks. Flexible braided hose helps reduce transmitted vibration and should be rated for the pressure expected in the system.\u003c\/p\u003e\u003cp\u003eBefore adjusting the pre-charge, switch off power to the pump and open a faucet to relieve system pressure. Tank pressure can then be checked with a standard tire gauge and adjusted with a tire pump at the air valve. After installation, run water through the pump and final discharge point to clear air from the system.\u003c\/p\u003e\u003ch6\u003eCompatibility and use on board\u003c\/h6\u003e\u003cp\u003eThis range is a practical match for boats with pressure-switch freshwater pumps serving sinks, showers, or water heaters. The 1 liter model suits installations with a little more room and a need for a larger pressure buffer, while the 0.65 liter model fits smaller spaces where a compact accumulator is easier to place near the pump.\u003c\/p\u003e\u003cp\u003eThe 0.65 liter model may also be used with air-driven pump systems. For any installation, a relief valve set no higher than 125 psi (8.6 bar) on the pump discharge side helps protect the water system if a pressure switch fails.\u003c\/p\u003e","brand":"Jabsco","offers":[{"title":"1 Liter","offer_id":52581966348469,"sku":"QBP254636-V1","price":123.99,"currency_code":"USD","in_stock":true},{"title":"0.65 Liter","offer_id":52581966381237,"sku":"QBP254636-V2","price":107.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1334449_qbp254636.png?v=1780201864"}],"url":"https:\/\/www.qualityboatparts.com\/collections\/accumulator-tanks.oembed","provider":"Quality Boat Parts","version":"1.0","type":"link"}
