"All Fuel saved the day! I took my stovepipe apart to clean it and did not realize that the top flange slips down the pipe. I thought that I had pushed the pipe up through the ceiling support box! Had a roofer out who assessed from topside and told me it looked good up there. I called around to other businesses and they “required” a tier 2 inspection for a cost of $359 and additional charge to come back out. All Fuel had me send photos and advised me that the pipe was fine and that I just needed to pull the end of the pipe upward to reconnect! Free of charge! They are reputable and honest and empathetic. I will use them for ANY AND ALL NEEDS! You can trust them. Thank you All Fuel!! Customer service 10 Star"

Dishwasher Installation questions, answered by experts

Yes, a dishwasher needs an air gap to prevent backflow. Additionally, in many locations, air gaps or another measure to prevent backflow are required for building code compliance. There are alternatives to an air gap, like a Studor vent or a loop and trap design, but an air gap is the simplest and most popular solution.  

To clean an old dishwasher without a filter, start by removing the bottom rack to access the drain area. Use a damp cloth or sponge to wipe down the interior, paying special attention to the corners and crevices where food particles and debris can build up. Pour a cup of white vinegar into a dishwasher-safe bowl and place it on the top rack, then run a hot water cycle to help break down grease and grime. After the cycle, sprinkle a cup of baking soda across the bottom of the dishwasher and run a short hot water cycle to deodorize and further clean the interior. 

Yes, you can use vinegar to unclog a dishwasher. To do so, combine 4 tablespoons of white vinegar with 4 tablespoons of baking soda and pour the mixture down your dishwasher’s drain. Let it sit for 15 minutes, then pour a cup of hot water down the drain to flush everything out. Finally, run a rinse cycle on your dishwasher to see if the clog is gone.

The only way to repair a dishwasher door hinge is to replace the broken or damaged hinge. To do this, you'll want to remove the old hinge, install a new one that fits your specific dishwasher model, and reattach the panel.

Your dishwasher drains through a hose that attaches to the plumbing below your sink or snakes out the back of your machine. In most cases, you can access one side of the hose from below your sink, as it usually ties into the same drainline that your sink uses. Otherwise, you may need to pull the dishwasher out of the counter to access it.
