I have done both the thermocouple sensor and the themal fuse-the former cost (parts) $18, the latter $16 at a plumbing supply house. Each took about 30 minutes to replace and I did it myself.

Using the squatty potty for elimination will reduce straining and decreases the pressure in the veins. The reduction of straining will help to heal and prevent hemorrhoids. It will also reduce the risk of bowel herniation and other damage to the lower digestive tract. The Squatty Potty is attractive and will discretely tuck under your toilet bowl when not in use.
Symptoms of hemorrhoids include: Bright red blood on the toilet paper after having a bowel movement, especially if the stool was very hard or very large. Blood also may streak the surface of the stool, or color the water in the toilet bowl. For a prolapsed hemorrhoid, a soft, grape-like mass protruding from the anus that may discharge mucous.
