In rare cases, hypokalemia is caused by too little potassium intake. Many things can cause potassium loss. The most common cause is the use of diuretics, or pills that cause urine production. Diarrhea, vomiting, and excessive use of laxatives can also cause symptoms.
How to Use a Trencher. When it comes to digging, a trencher can dig a trench that's 4 feet wide and up to 36 inches deep. Use these step-by-step instructions to easily dig a hole in no time with the right equipment.
Check yourself as you go. For instance, if the trench for the French drain is to be 100 feet long and the grade 1%, then by the time your trench is 50 feet long, it should be 6 inches deeper than where you began excavating. You will be digging a horizontal trench across the length of the slope.
