Adding a hose extension might potentially help in preventing the overflow issue from the wall drain during the rinse cycle. By extending the hose, you allow the water to travel a longer distance, which could provide more time for the water to drain properly before the next rinse cycle starts. However, there are some important considerations to keep in mind:
Height and angle: If you plan to add a hose extension, ensure that it is properly elevated and secured. The extension should have a slight upward slope from the washing machine to the wall drain. This angle encourages water flow and helps prevent any potential water backflow.
Drain capacity: Check the capacity of the wall drain to ensure it can handle the increased water flow from the extended hose. If the wall drain has limited capacity, the extension may not completely solve the problem.
Hose diameter: If you use a hose extension, ensure that the extension has the same diameter as the original hose. Using a smaller diameter hose can lead to slower drainage and exacerbate the issue.
Clogs and blockages: Check for any clogs or blockages in the hose, drain pipe, or wall drain. If there are any obstructions, clearing them will likely improve drainage.
Plumbing regulations: Before making any modifications, make sure to check local plumbing regulations to ensure you are compliant.
If adding a hose extension does not resolve the issue, there might be an underlying problem with the plumbing or drainage system that requires professional inspection and repair. In such cases, it's best to contact a plumber or appliance repair technician to diagnose and fix the problem appropriately.
