A Guide to HVAC Units for the Amateur

When our family first moved into our home five years ago, the central heating and air unit were brand new. We never considered that there would be a time when it would not be operating as we wanted it to. When the time to buy a new unit came, we found that the available options were more diverse than we thought. It was all too confusing. After researching the different options, I decided to create this blog. My hope is that others who are faced with this decision can find easy-to-understand information that can aid in quickly making an informed decision.

4 Reasons You Don't Have Good Hot Water Pressure


When you lose water pressure in your home, there are many things that could contribute to it. However, if you are only losing hot water pressure, that list is considerably shorter. If you turn on the faucet and the pressure is fine when using cold water, but low when using hot, the following issues may be what is causing it.

Problems With the Cold Water Line

Believe it or not, one of the top reasons for low hot water pressure is actually due to an issue with the cold water line. While the pressure coming from the cold water line is what comes out of your hot water heater, a problem with this line can actually effect how good the hot water pressure is.

When there is an issue with the cold water line, the hot water doesn't fill up enough or quickly enough to provide a good amount of hot water when the faucet is turned on. This is often from a home water tank issue or even a city water system issue.

There is Sediment Buildup

Over time, your hot water heater can start building up sediment. As sediment builds up, the debris and rust can start leaking into the hot water line. As it does, it backs up the water line and causes the hot water pressure to be low.

If you believe this is the problem, have the hot water heater drained and flushed. After it has been flushed, repeat the process a few times a year to prevent it from happening in the future. A plumbing company like A Absolute Plumbing & Heating will be able to flush out your water heater and improve the pressure if this is the cause.

The Faucet Needs Repairs

Sometimes, the pressure of the hot water has nothing to do with the water line or water heater, but is more localized. The first thing you should do when checking water pressure is start at the faucet or showerhead that is giving you problems. If it only happens when you are in the shower or at one of your sinks, it is probably due to that faucet.

However, it is occurs throughout your home, the fixtures are probably not the cause of the low water pressure. You can try cleaning the faucets and shower head to remove debris that might be causing the low pressure, or replace them entirely.

The Shutoff Valves Are Defective

The last reason why your hot water pressure might be low is due to the shutoff valves, which shut the water off. You should have valves that completely shut the water supply to certain areas of the home. Over time, they might get clogged, get wear or tear, or break. If this happens, it can affect the water pressure. Shutoff valves are usually attached to the hot water lines, which is why it generally causes low pressure with your hot water only.
