A Sink Sink may have a leak at several sources due to stresses caused by tight gripping or overstretching of the hose etc. At a low cost of $15 (for the purchase of a new spray and hose unit), you can fix the problem yourself. Although you can carry out the repair work without interrupting the water supply, be careful not to switch on the tap at the wrong time. Here’s how to do the job.
Step 1 – Find the leak
First switch on the water tap and press the trigger of the syringe. Now carefully check the spray head for signs of leakage. Then check the plastic coupling connecting the host and spray head for signs of leakage. The third place to look for leaks is under the sink where the tap is connected to the hose.
Step 2 – Leakage at the plastic coupling
If the leakage is on the plastic coupling, tighten the connection. To do this, grasp the sprayer firmly and turn the coupling clockwise as far as possible.
Step 3 – Check for leaks
Now turn on the tap and press the trigger again to check if the problem has been fixed. If not, proceed to the next step.
Step 4 – Check the plastic sleeve
Turn the plastic coupling counterclockwise to remove the spray head. Now switch on the water tap again and check the plastic sleeve of the hose for leaks.
Step 5 – Replace the hose and head
If the leak is still present, replace the spray head and hose.
Step 6 – Check the Washers
Press the washers in the clutch and if you can feel any movement, they may have dislocated. If not, continue.
Step 7 – Check for leaks
Replace the coupling, hose and spray head. Repeat the first step to check for leaks. If the problem persists, disconnect the plastic coupling and spray head as before.
Step 8 – Replace the discs
Use a screwdriver to lever out the washers located on the coupling. Push in the new washers firmly instead of the old ones.
Step 9 – Check for leaks
Replace the coupling, hose and spray head. Repeat the first step to check for leaks.
Step 10 – Tighten the tap connection
If the leak was under the sink, use a wrench to tighten the tap connection. If the leak is still present, loosen the hose and tap with the wrench. In this case, disconnect the water supply before disconnecting the hose.
Step 11 – Dry the threads
Dry the external and internal threads of the faucet and hose and unwind the external threads with a Teflon tape.
Step 12 – Final Inspection
Connect the hose and tap by first screwing them together and then using a wrench. If the leak persists, replace the entire hose and syringe.
Field Service for the heating, ventilation, air conditioning and sanitary industry
One of the most important concerns for the building services industry (HVAC) is customer satisfaction. There are a large number of competitors, so that customers whose needs and requirements are not met quickly migrate to the competition. This means that building services companies must primarily focus on providing the best possible customer experience.
With HVAC Escondido, you stand out from the competition. Our Field Service Management solution enables automated and intelligent scheduling, dispatching and tracking of your technicians – with real-time updates of status and arrival times for customers and back office.
With easy integration of ERP and CRM systems, you can make service offers to customers, invoice immediately, check performance against customer feedback and repair times, keep pace with and proactively renew SLAs, and generate reports.
Preventive maintenance of heating and cooling systems is becoming increasingly important. This leads to an increased need for service personnel to meet customer service needs.
Challenges for the Building and Air Conditioning Industry
(1) Balancing costs and revenues
The strong competition in the HLKS industry makes it difficult to increase sales through pricing. So building services companies need to find other ways to adjust their spending.
(2) Selling results
Customers have less interest in buying a device. Rather, they want to see results. They want to buy comfort, but not air conditioning or heating. Therefore the next necessary step is the integration of IoT and Artificial Intelligence. The more devices are integrated, the more important predictive maintenance becomes in order to avoid unscheduled downtimes.
(3) Safety and guidelines
Depending on the application areas of the respective devices, the building services industry must comply with very specific guidelines. For example, the food industry demands very strict standards for cooling and refrigeration systems. These security processes require careful monitoring.
(4) Inventory costs
The equipment of home and air conditioning technicians includes a variety of spare parts, some of which need to be repaired or replaced more often than others. Service companies need an intelligent and comprehensive spare parts demand analysis system to avoid unnecessarily high storage costs.
