20+ years old system, uses R22, compressor had failed and furnace is leaking carbon monoxide. Based on our findings today, it might be time to think about getting a brand new system for main floor/basement.

Today I completed a plumbing evaluation due to concerns about a high water bill. During my inspection, I found that the home water pressure is currently higher than the recommended range, which can cause fixtures to drip, operate, improperly, or fail prematurely. I also inspected the home pressure reducing valve and found that the PRV is actively dripping. A continuously dripping PRV can’t contribute to increase water usage and may be a factor in the higher water bill. I explained these findings to the tenant on site. He attempted to contact the landlord for approval, but she was not available to answer the phone at this time. I advise that correcting the high water pressure and addressing the leaking PRV is important in order to prevent further fixture issues and avoid continued water loss. I will be providing repair options along with this invoice for the Landlord to review.

Today at Mr and Mrs Slades home, I arrived to find they are having issues with the hammer arrestors at the washing machine. After further inspection, we determined the removable hammer arresters need replacing. I determined there were no other outstanding issues. As a part of water quality awareness, we performed a complimentary water test to see the quality of the water in the home. They had high chlorine and neutral pH. We decided to “fix” the water with an H2Zero Ultimate filtration system Installed H2 zero ultimate filtration system in basement utility room, and installed secondary settlement filter at same location. Removed and replaced hammer arresters at washing machine box. Also drained and flushed water heater as it is only three years old at no extra cost to the customer How’s pressure is set at 72 psi with the new PRV All air has been removed from system and everything is working with clean filtered high alkaline water
