Miah came for the diagnosis and was very thorough with his check. After taking videos to show me what the issues were, we decided to change the entire water heater. Miah then came again with Arun the next day to install a new heater. I appreciate how they took extra care to not dirty my apartment and did their best to restore it to its original state. Happy with the quick and professional service

Gas Leak Testing

Gas Leak Testing – After Gas Water Heater Replacement

  • One commonly used gas leak testing machine is a gas leak detector.

  • This handheld device is equipped with sensors that can detect the presence of certain gases, such as natural gas or propane. The detector is moved around the area or equipment being tested, and if it detects a gas leak, it will typically emit an audible or visual alarm to alert the user.

Gas Pressure Gauge Test – After Gas Water Heater Replacement

  • Before and after replacing a gas appliance or conducting maintenance on a gas system, it is common practice to measure the gas pressure using a gas pressure gauge. The purpose of this test is to ensure that the gas pressure is within the appropriate range for safe and efficient operation.

  • Before the replacement or maintenance, the gas pressure gauge is connected to the gas line, typically at a convenient access point such as a gas valve or a test port. The gauge measures the pressure of the gas flowing through the line, and the reading is recorded.

  • After the installation or maintenance is complete, the gas pressure gauge is again connected to the gas line, and a second reading is taken. By comparing the initial reading to the final reading, it can be determined if there are any significant changes in the gas pressure.

  • This test is important because incorrect gas pressure can lead to various issues such as inefficient combustion, appliance malfunctions, or even safety hazards. By monitoring the gas pressure before and after any work, it helps ensure that the gas system is functioning properly and that the appropriate gas pressure is being delivered to the appliances.

Final pressure test on completion of a gas water heater installation using an U-Gauge Manometer

  • This gauge consist of a glass or transparent plastic tube containing water.

  • It can measure pressure of up to 30mbar gauge.

Paloma Gas Heater Replacement in Singapore (Jan 2026)

My Paloma gas heater wasn’t working, and I approached many plumbers in search of assistance. Unfortunately, as gas heaters required a PUB-licensed plumber, I was told by 4-5 companies that they weren’t able to assist. Another 1-2 rejected my case as it was a Paloma heater and they were no longer operating in SG. I finally managed to find HomeOne after 3-4 months, and Harpreet was so professional and knowledgeable he was able to determine the problem quickly.

Tamal and Faisal were also able to help with the replacement of the Paloma heater quickly after, wand from consultation to replacement, everything was resolved within a week. Very glad to have found this company - great service thus far!

Rinnai Gas Heater Replacement in Singapore (Jan 2026)

Decided to change my gas water heater that I had been using for 13 years. During these 13 years, I had repeated inconsistent hot water supply issue. Maintenance once at about 5 years. In my search for a replacement. I chose Rinnai and HomeOne for the removal and installation. The experience is really great with HomeOne. Starting from the WhatsApp engagement with Mr Eng who replied me fast on the same day and provide good recommendation and advisement.

Appointment was booked two days later. The technicians, Rubel and Aminul who came were friendly. They were detailed and done the job professionally. Gas pressure and leak test was done. Wall remote controller installed with paint touch up done nicely. If anyone needs their gas hot water heater replacement, go engage HomeOne and their technicians. You will not be disappointed.
