It ships with its drain plug and o-ring, so the housing goes back on the pump with a fresh seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich PB4-60 do you have?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis volute fits PB4-60 pumps manufactured from 2011 to current, serial number PB120111001 and later. The quickest check is the housing cover: on the new style the ridges extending from the center hole are curved, on the old style they are straight. Straight ridges mean you need the P5 volute rather than this part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it fixes\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA cracked or warped volute is one of the usual reasons a booster pump starts spraying water at the front. The housing comes off without disturbing the motor, and with the drain plug and o-ring already included there is nothing else to source for the housing itself.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhile you are in there\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIf the pump has been leaking for a while, consider replacing the backplate o-ring and the 13\/16 in. shaft seal at the same time. Both are separate parts.\u003c\/p\u003e","brand":"Zodiac","offers":[{"title":"Default Title","offer_id":48624877994196,"sku":"POL-101-5363","price":66.87,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_7c76ca57-fb3a-4602-a092-51b478b89803.jpg?v=1788648580","url":"https:\/\/www.activepoolsupply.com\/products\/front-housing-volute-with-o-ring-pb4-60-new-style","provider":"Active Pool Supply","version":"1.0","type":"link"}
