AC Drain Hoses

The actual hose inside diameter must match the appliance drain outlet and connector. 5/8″ may be referred to commercially as approximately 16 mm; confirm the actual dimensions against the outlet and product declaration.

Insufficient slope, crushing, dirt, insects or a closed outlet can cause water to back up. Check the route and outlet regularly.

Confirm that the PVC product is suitable for the sunlight and temperature conditions. For an outside wall installation, evaluate the current UV and temperature declaration together with the fixing method.

Choose the diameter according to the appliance outlet, connector, condensate volume and installation route. Do not order on an assumed 16 or 20 mm size without checking the outlet.

5/8″ converts mathematically to 15.875 mm and may be called approximately 16 mm commercially. Check actual inside and outside diameters and connector compatibility for the product series. The conversion alone does not guarantee a fit.

Measure the installation route, horizontal and vertical distances, bends, service allowance and number of joints. Consider continuous lengths, storage and service planning rather than unnecessary extra rolls. These lengths are requirement examples; confirm the selected series’ roll length and stock separately.

Plan a continuous route with the slope required for safe drainage from the appliance. Elevation changes and bends can make the actual length greater than the straight-line distance; measure on site.

Use a connector of the same or a compatible actual size, and keep the joint accessible and leak-tight. Do not crush the hose or create reverse falls or water pockets.

Match the connector to the actual hose diameter, flow direction and installation space. Each extra joint can introduce leakage or blockage points, so keep the route as simple as practical.

Check for water pockets, reverse falls, dirt, outlet backflow or an incorrect connection to a shared drain. Cleaning and connection methods must follow the appliance service instructions.

Check the outlet connection, slope, crushing, joints, appliance drain tray and whether the drain end is open. If the problem persists, obtain an assessment from the authorised service provider or installer.

Diameter, roll length, product series, outdoor or UV requirements, fittings, order quantity and shipping affect the quotation. Confirm the current price on the product page or in a written quotation.

Plan support points without crushing the hose; avoid sharp clamps and overtightening. Consider UV, heat and mechanical impact conditions separately for outside walls.

Provide the required actual size or confirmed 5/8″ product record, total metres or rolls, indoor or outdoor use, appliance type, fittings, delivery city and target date. Do not assume that other sizes are stocked from the category name alone.

Choose a method compatible with the hose material and installation. Check restricted flow, dirt and trapped water first; do not use chemicals or high pressure without the relevant product declaration.

5/8″ equals 15.875 mm mathematically and may be grouped with nominal 16 mm products. Check the appliance outlet, actual hose dimensions and connector tolerance separately.

Measure the actual route, bends and appliance connection length separately for each installation. Add the installation lengths and show the purchasing allowance separately. Dividing total metres by roll length alone may not account for continuous-length requirements.

Maintain a compatible drain connection, sealing and the slope in the manufacturer’s instructions. Avoid reverse falls and water pockets. An extension does not by itself solve blockage or the need for pumped drainage.
