The product title also lists it for FNS Plus filters, so it turns up under both families; check the model plate on your tank before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe bulkhead is the fitting at the base of the filter tank where the tank passes through to its plumbing. It carries the full pressure of the system and is sealed against the tank, which makes it one of the first places to look when a DE filter starts weeping low down.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReplacing it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe bulkhead is a serviceable part in its own right, so a base leak does not automatically mean a new tank. If the tank body itself is cracked or distorted, the complete tank bottom assembly is the larger repair, but a failed bulkhead is fixed with this part alone.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48626601230548,"sku":"PAC-051-1852","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_7a289aac-c22c-49b6-b9f5-bc529a8dd7be.jpg?v=1788712925","url":"https:\/\/www.activepoolsupply.com\/products\/pentair-178575z-bottom-bulkhead-for-quad-d-e-filter","provider":"Active Pool Supply","version":"1.0","type":"link"}
