4. Installationsvejledning
Follow these steps to install the PROFLO PF74VBKIT Vacuum Breaker Repair Kit:
- Sluk for vandforsyningen: Locate the main water shut-off valve for the spigot or faucet and turn it off completely. Open the spigot to drain any remaining water.
- Remove Old Vacuum Breaker: Carefully unscrew and remove the existing vacuum breaker cap and any internal components from the spigot. Note the order of the parts as you remove them.
- Rengør området: Thoroughly clean the threads and the opening of the spigot where the vacuum breaker sits. Remove any debris, mineral deposits, or old sealant.
- Saml nye komponenter:
- Place the small black rubber washer onto the white plastic vacuum breaker stem.
- Insert the brass retaining screw into the top of the white plastic stem.
- Install New Vacuum Breaker: Insert the assembled stem and screw into the main beige vacuum breaker cap.
- Attach to Spigot: Carefully thread the lower threaded cap onto the spigot's outlet. Ensure it is hand-tightened first, then use channel locks for a snug fit, being careful not to overtighten. For an enhanced seal, a small amount of plumber's putty can be applied to the threads before tightening.

- Tjek for lækager: Inspect the newly installed vacuum breaker for any signs of leaks. If leaks are present, turn off the water, re-check all connections, and ensure components are properly seated.
5. Operating the Vacuum Breaker
Once installed, the vacuum breaker operates automatically to prevent backflow in your PROFLO PF73 or PF74 series spigot or faucet. It is a passive device that activates when pressure conditions could lead to contaminated water being siphoned back into the potable water supply. No manual operation is required for the vacuum breaker itself. Ensure the spigot functions normally with no leaks and that water flows freely when opened.
6. Vedligeholdelse
The PROFLO PF74VBKIT is designed for durability, but periodic inspection can prolong its life and ensure continued performance:
- Visuel inspektion: Periodically check the vacuum breaker for any visible signs of wear, cracks, or damage.
- Lækagetjek: Regularly inspect the connection points for any drips or leaks, especially after periods of non-use or extreme temperature changes.
- Rensning: If mineral deposits or debris accumulate around the exterior, gently clean with a soft cloth and mild soap. Avoid harsh chemicals that could damage the plastic components.
- Vinterisering (hvis relevant): In freezing climates, ensure outdoor spigots are properly drained and protected from frost to prevent damage to the vacuum breaker and the spigot itself.
7. Fejlfinding
Hvis du støder på problemer efter installation af reparationssættet, skal du overveje følgende:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Leakage after installation | Improper tightening, damaged washer, incorrect component seating, or incompatible threads. | Turn off water, re-tighten connections (do not overtighten), ensure the rubber washer is correctly seated, and consider using plumber's tape or putty on threads. Verify thread compatibility with your spigot model. |
| Kit does not fit spigot | Incompatible spigot model or thread size. | This kit is designed for PROFLO PF73 and PF74 Series. Verify your spigot's model number and thread specifications. Some spigots may have slightly different thread diameters (e.g., 0.795" vs 0.845" outside diameter threads). |
| Vandgennemstrømningen er begrænset | Debris in the line, or internal components not seated correctly. | Turn off water, remove the vacuum breaker, check for any obstructions in the spigot or the vacuum breaker components. Reassemble carefully. |
