前兩周一個房子的地下室管子漏水，plumber過去發現是下水管堵了。今天收到賬單是這樣的，共$1300：
1. Snake and flush main sewer line. Snaked main line from the house trap to the street appreoximately 30 feet clearing the line flushed and test ed the line is clear.
2. House Trap, auger house trap clearing blockage caused by wipes and hair flushed and tested the line is clear.
3. Replaced 4" cracked and leaky 4" horizontal lines.
第2項說堵的原因是wipes and hair，是不是隻是堵在house trap，第1項裏的sewer line並沒有堵？
房子裏有兩戶，都住了3－4年了，第一次出這種問題。Lease裏是這麽寫的：
DRAIN STOPPAGES: As of the date of this Agreement, Management warrants that the Premises' sewage drains are in good working order and that they will accept the normal household waste for which they were designed. They will not accept things such as diapers, sanitary napkins, tampons, condoms, children’s toys, wads of toilet paper, balls of hair, grease, oil, table scraps, clothing, rags, kitty litter, sand, dirt, rocks or newspapers. Residents agree to pay for clearing the drains of any and all stoppages except those which the plumber who is called to clear the stoppage will attest in writing were caused by defective plumbing, tree roots, or acts of nature.
裏麵沒有列出wipes, hair，是否需要添加進去？大家遇到這種情況會要房客分擔部份賬單嗎？或者是這次我付了，再有下次就要房客付。
