Taps & shut-off valves

Distinguish between three installation situations

Record threads correctly

Record the following separately at the inlet and outlet: female or male thread, full thread designation, existing sealing surface and available space. A measured external diameter does not directly correspond to the nominal size of an inch thread. For connections to a hose or quick-release coupling, add the hose tail size or system profile.

Plan for operation and safety

• The handle must remain accessible in every position and must not hit a wall or tank.
• The weight of the connected hose must not place an excessive load on the outlet; support the line separately if necessary.
• For outdoor fittings, provide frost protection and drainage appropriate to the design.
• For drinking water connections, have the required backflow protection assessed professionally.
• Take medium, temperature and pressure limits only from the specific product and system approvals.

The DVGW explains protection for outdoor water outlets: even a standard outdoor outlet needs a suitable protective device; more demanding applications require a separate assessment by a specialist company. “Fits the thread” is therefore not enough to establish suitability for a drinking water installation.
