Show I FIRST AID to the AILING HOUSE 1 j by Roger C. Whitman QUESTION: Our drains are stopped up very often in spite of the fact that we have had the pipes cleared by a tree-rooter machine. ma-chine. I am of the opinion that it is a clogged vent and not tree roots in the pipes. Can you give me any advice? ANSWER: It is possible that the pitch of the horizontal soil pipe is insufficient, so that grease and other sediment matter congeals and closes up the line and retards the flow of waste matter to the sewer. Re-laying of the pipe is one solution, if that is the case. I doubt if a clogged vent would cause the condition. The other solution to such a problem is to install in-stall a grease trap in the line from the kitchen sink and clean it out periodically. |
