A cracked or degraded drum loses its sealing and structural integrity, reducing system performance and potentially allowing untreated water to bypass the filter. This replacement drum restores the full settling chamber volume. Compatible With Pondmaster P-4000, PUV-4000 Function Settling chamber and pre-filtration housing Component Large drum body (chamber replacement) Installation Drain and disconnect the existing drum from the pump and plumbing before removal. Transfer seals, fittings, and any media from the old drum to the new one, clean all reused components before reinstalling. Reconnect inlet and outlet plumbing, ensuring all fittings are hand-tight before adding a quarter-turn with a strap wrench. Refill the system and check for leaks before restoring full pump flow. Fits the Pondmaster P-4000 pump system and PUV-4000 UV clarifier only. Confirm system model before ordering.","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/pondmaster-replacement-parts-default-title-pondmaster-large-drum-for-p-4000-puv-4000-43287417192767.webp?v=1790197018","href":"/product/pondmaster-large-drum-for-p-4000-puv-4000.html","buy_url":"https://xyjpsn-3p.myshopify.com/products/pondmaster-large-drum-for-p-4000-puv-4000","buy_url_source":"shops.shop_domain + product.handle","seller_name":"xyjpsn-3p.myshopify.com","seller_url":"https://xyjpsn-3p.myshopify.com/","return_policy_url":"https://xyjpsn-3p.myshopify.com/policies/refund-policy","media":[{"url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/pondmaster-replacement-parts-default-title-pondmaster-large-drum-for-p-4000-puv-4000-43287417192767.webp?v=1790197018","alt":null,"position":0}],"related":[{"handle":"aquascape-smart-control-receiver-1","title":"AQUASCAPE SMART CONTROL RECEIVER","category":"Replacement Parts","price":"$138.31","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/aquascape_smart_controller_reciever_45038.jpg?v=1790199478","sku":"AQP-45038**DISC**","href":"/product/aquascape-smart-control-receiver-1.html"},{"handle":"oase-1-2-hp-floating-fountain-replacement-pump","title":"Oase 1/2 HP Floating Fountain - Replacement Pump","category":"Replacement Parts","price":"$285.59","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/oase_replacement_pump_with_75_ft_cord_for_.5_hp_floating_fountain_with_lights.jpg?v=1790198499","sku":"OASP-49522","href":"/product/oase-1-2-hp-floating-fountain-replacement-pump.html"},{"handle":"oase-24w-uvc-replacement-bulb-for-filtoclear-4000-g2-filtoclear-3400-g3-and-bitron-c-24","title":"OASE 24W UVC Replacement Bulb for Filtoclear 4000 (G2), Filtoclear 3400 (G3), and Bitron C 24","category":"Replacement Parts","price":"$60.89","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/bitron_36w_uv_bulb_1_1.jpg?v=1790199589","sku":"OASP-41011","href":"/product/oase-24w-uvc-replacement-bulb-for-filtoclear-4000-g2-filtoclear-3400-g3-and-bitron-c-24.html"},{"handle":"oase-18w-uvc-replacement-bulb-for-vitronic-18-and-filtoclear-3000","title":"OASE 18W UVC Replacement Bulb for Vitronic 18 and FiltoClear 3000","category":"Replacement Parts","price":"$55.99","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/bitron_36w_uv_bulb_1.jpg?v=1790199593","sku":"OASP-40965","href":"/product/oase-18w-uvc-replacement-bulb-for-vitronic-18-and-filtoclear-3000.html"}]}}
