Use it to replace a worn or damaged kit, or to connect an IWS FlexiTank or another reservoir to an IWS system. The \u003cstrong\u003eStandard\u003c\/strong\u003e kit carries a NEWA Maxi-Jet \u003cstrong\u003eMJ1000\u003c\/strong\u003e and suits 16mm IWS Standard and Standard Remote systems; the \u003cstrong\u003ePro\u003c\/strong\u003e kit carries a NEWA Jet \u003cstrong\u003eNJ3000\u003c\/strong\u003e with the blue IWS connector and suits 25mm Pro Remote and Trident systems. Both are made for current IWS tanks with a single drain connection, and IWS make a kit for each FlexiTank size, so choose the size of the tank it will sit in. A pump that fades or a split fill line shows up quickly as slow, uneven floods, so keeping a genuine kit to hand avoids lost feeds.\u003c\/p\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard 16mm kit\u003c\/strong\u003e: long-lead MJ1000 pump with fill pipe, anti-syphon tube and grommet; long fill pipe; long and short drain pipes; two threaded connectors; four washers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePro 25mm kit\u003c\/strong\u003e: long-lead NJ3000 pump with blue IWS connector; anti-syphon fill pipe; long fill pipe; long and short drain pipes; two threaded connectors; four washers\u003c\/li\u003e\n\u003cli\u003eFlexiTank not included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine IWS parts\u003c\/strong\u003e, matched to the IWS brain and FlexiTank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug-in power\u003c\/strong\u003e: the pump connects straight to the IWS brain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnti-syphon fill pipe\u003c\/strong\u003e stops the tank siphoning back between floods\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo pump sizes\u003c\/strong\u003e: 1,000 L\/h for Standard systems, up to 3,000 L\/h for Pro and Trident\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit per tank size\u003c\/strong\u003e from 100L to 750L\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFit the threaded connectors through the tank with a washer either side; hand-tighten, then nip up gently\u003c\/li\u003e\n\u003cli\u003eConnect the fill and drain pipes from the tank to the brain\u003c\/li\u003e\n\u003cli\u003eStand the pump on the tank floor and plug its lead into the brain\u003c\/li\u003e\n\u003cli\u003eFill the tank with water and run a test flood and drain before adding nutrients\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e IWS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersions:\u003c\/strong\u003e Standard 16mm (MJ1000 pump) or Pro 25mm (NJ3000 pump)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank sizes:\u003c\/strong\u003e 100L, 250L, 400L and 750L FlexiTank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard pump:\u003c\/strong\u003e NEWA Maxi-Jet MJ1000: 1,000 L\/h, 13W, max head 1.5m, IP68\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePro pump:\u003c\/strong\u003e NEWA Jet NJ3000: 1,200-3,000 L\/h, 55W, max head 2.9m, IP68\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector:\u003c\/strong\u003e Long lead with blue IWS (Bulgin) connector to plug into the IWS brain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank connection:\u003c\/strong\u003e Single drain, for current IWS FlexiTanks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible with:\u003c\/strong\u003e Standard: IWS Flood \u0026amp; Drain Standard and Standard Remote.
