Inquiry (采购产品): Sewage Pump I have a three storey house in Pakistan that includes a Basement. The Basement has two bath/wash rooms and a kitchen. The sewage and waste water from the bath/wash rooms and the kitchen flows into a septic tank from where it is pumped out into a gutter with the help of an ordinary centrifugal pump. The pump functions with the help of a check valve. It runs on electricity and is switched on and off automatically by a level switch. With the passage of time, the check valve gets clogged because of the sewage and sludge as well as greasy material flowing from the kitchen. These kinds of materials stick onto the outer and inner portions of the valve making it non-functional. To my mind, sewage pump that works without a check valve may serve the purpose without any hassle. What type of pump would you suggest for use in this situation please? **** Hidden Message ***** M Younus Khokhar House 216, Street 58, G-11/2, Islamabad44000 PAK Company: Domestic Use Phone: 00 90 300 950 4372 E-mail: mykhokhar2001@gmail.com **** Hidden Message ***** mykhokhar2001@gmail.com
