Water drains through, and radon stays out.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePouring a new basement floor is the best time to get the floor drain right. The FN2 comes as a full drain: the housing, an anchor flange that sets into the concrete, the seal assembly and a strainer plate. Set it in the pour and the drain never becomes a way in for radon and soil gas.\u003c\/p\u003e\n\u003cp\u003eIt's designed for homes with an active sub-slab depressurization (radon fan) system, or one that's planned. Dranjer, a Canadian company in Winnipeg, engineers and tests its drain seals in the lab and in the field.\u003c\/p\u003e\n\n\u003ch3\u003eHow it works\u003c\/h3\u003e\n\u003cp\u003eInside the drain, a sealing ring sits closed. When water comes in, the ring lifts and the water flows through. Once the water stops, the ring reseats and blocks radon, soil gas and odours from coming up the drain.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eUse PVC solvent cement to join the housing to the anchor flange and to the drain plumbing.\u003c\/li\u003e\n\u003cli\u003ePour the concrete around the drain, level with the top of the anchor flange. The flange's reverse bevel keeps it from lifting out.\u003c\/li\u003e\n\u003cli\u003ePush the seal assembly into the anchor flange. A light coat of petroleum jelly on the flange seal helps it seal.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart number\u003c\/td\u003e\n\u003ctd\u003eDranjer FN2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFits\u003c\/td\u003e\n\u003ctd\u003eStandard 2 in (5.08 cm) pipe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTop diameter\u003c\/td\u003e\n\u003ctd\u003e3.9 in (9.9 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExterior dimension\u003c\/td\u003e\n\u003ctd\u003e2.75 in (6.99 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHousing\u003c\/td\u003e\n\u003ctd\u003e4 in (10.16 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeal assembly depth\u003c\/td\u003e\n\u003ctd\u003e3.75 in (9.53 cm) below the floor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncludes\u003c\/td\u003e\n\u003ctd\u003eHousing, anchor flange, seal assembly, strainer plate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNot included\u003c\/td\u003e\n\u003ctd\u003e2 in street fitting or pipe below (customer supplied)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSold\u003c\/td\u003e\n\u003ctd\u003eIndividually\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eDranjer Corporation, Winnipeg, Canada\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCommon questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it need any maintenance?\u003c\/strong\u003e\u003cbr\u003eIf the drain gets used regularly, lift the strainer plate now and then and rinse the seal assembly with clean water.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the FN2 go into a floor that's already poured?\u003c\/strong\u003e\u003cbr\u003eYes.
