Reinforced PVC Drinking Water Hose – Food-Grade (Ø12–50 mm)

This reinforced PVC drinking water hose is specifically designed for freshwater supply on boats, yachts, RVs, and other systems requiring clean potable water. The materials used are approved for food and drinking water contact, meaning the hose will not leach harmful chemicals into your water or affect its taste. This is crucial for situations where water may sit in the hose for extended periods – such as the potable water stored in a yacht’s tank.

Construction and Advantages:

• Non-Toxic, Certified PVC: The hose complies with Directive 90/128/EEC and other relevant standards for safety. This ensures the hose’s inner lining is water-neutral – free from phthalates, and it won’t impart any plastic taste or odor. Your drinking water remains fresh and pure, even after standing in the hose during hot weather.
• Textile Reinforcement: Embedded within the hose wall is a braid of strong synthetic fibers that gives it additional strength. Thanks to this reinforcement, the hose can withstand significant working pressure (typically up to ~8-10 bar, depending on diameter) – more than enough for any onboard water pump. The braid also prevents kinks and collapse, keeping water flow consistent even around bends. The hose stays flexible yet resists pinching shut, which is critical in tight installation spaces.
• Flexible and Resilient: The PVC material is translucent with a light bluish or clear tint, allowing you to visually monitor water quality (you can spot any sediment or growth inside). It retains flexibility over a broad temperature range – roughly from -5°C up to +60°C (+23°F to +140°F). For example, if you pump warm water from a heater (~50-60°C), the hose will handle it without softening or leaking. In cooler weather, the material remains supple and is not prone to cracking, which is useful during early spring or late autumn boating.
• Sizes for Every Need: Diameters Ø12, 16, 19 mm are popular for connections from pumps to faucets, showers, and water heaters (1/2" and 5/8" are standard sizes for most plumbing fittings). Ø25 and 32 mm can serve for main distribution lines or linking a tank to a primary pump on larger vessels. The largest sizes Ø38, 45, 50 mm are perfect for tank filling lines (from a deck fill fitting down to the tank) or as trunk lines where high volume is required – for example, supplying a manifold that feeds multiple outlets.
• Uses and Recommendations:
  • Internal Connections: To connect a water tank to a pump, typically a Ø19 or 25 mm hose is used (depending on the pump’s inlet) because these lines need to carry a large volume with minimal restriction. From the pump to individual faucets/showers, a Ø12 or 16 mm hose is often employed, which eases routing through tight spaces and maintains adequate pressure to end fixtures.
  • Tank Filling: From the deck filler down to the water tank, we recommend a larger diameter like Ø32–38 mm for faster filling and less risk of back-splash. This hose is robust enough to handle pressure from a dock water hose when refilling at the marina.
  • Other Applications: This reinforced hose isn’t just for drinking water – it can serve as a general-purpose flexible hose for any clean fluid onboard. For instance, it can be used in shower drain systems or air conditioning circulation lines where a strong, safe hose is needed. Because of its food-safe nature, it’s also suitable for aquarium systems or food/beverage processing on land.
• Maintenance: It’s advisable to periodically flush the hose, especially when used for potable water. The transparency helps with inspection – if you notice bio-film or scale build-up, you can easily clean or replace the affected section. The hose material is compatible with common cleaning agents for water systems (e.g., mild vinegar solutions or baking soda flushes for sanitization).
