Hot Water Re circulation System: is a plumbed system that moves hot water to fixtures quickly without waiting for the water to get hot. Instead of common low pressure water lines, this system recirculates water moving from a water heater directly to the fixtures. There are two system types: Dedicated loop and Integrated loop.
This essay is about the inspection of an electric hot water heater. All labels with performance ratings are clear and legible. There is a mixing valve installed between the cold water inlet and the hot water outlet piping. The TPR Valve is mounted on the top of the tank. However, the drain pipe on the TPR Valve runs through the wall and with the end of the pipe concealed and not clearly visible.
This essay is about purpose of the expansion tank installed on the cold side of the a hot water system. The tanks’ purpose is to absorb the expansion and contraction of water as it heats and cools through the use of an internal bladder and air pad system. The system should be installed as to maintain a constant pressure throughout water tank and thus the distribution channels.
This is an electric hot water heater located on the screened in back porch of a 1920s home. It appears to be in good condition. There is a small amount of corrosion on the bottom edge, probably due to the location of the tank being in high humidity (Florida). Its TPR valve has a proper discharge pipe leading to the outside of the finished space. Also the plastic water leak pan is properly plumbed to the outside. The shut off breaker is only a few feet away and all wiring is in conduit. There are no leaks.
I read an article on galvanic corrosion. Galvanic corrosion occurs when dissimilar metals come in contact with each other in the presence of an electrolyte such as salt or rain water. The metal ions move from the active metal to the less active metal causing corrosion. To prevent this either prevent the contact of dissimilar metals, or protect the connection from contact with an electrolyte.
Underneath our house I noticed in the crawlspace there was loose wiring. I check to see if the line was hot and it was. So I called an expert to come in and fix it the right way that way it does not cause any harm.
Just read an article on how to avoid lawsuits while being a home inspector. To have proper signage and equipment for the inspection. Let the home owner what you are doing and where you are before you enter a certain area.
I have taken a picture of the labelling on my TPR Valve. It clearly indicates 150 PSI and 210 degrees fahrenheit. This particular hot water tank is for my in floor heating system and has an expansion tank attached. The TPR valve discharge is connected to a tube that carries it to the drain in the utility room.
I have studied the article, Water Heater Expansion Tanks by Ben Gromicko and Kenton Shepard. I was not aware that such a system existed prior to taking a number of modules on plumbing and hot water systems. I have seen numerous hot water tank installs over my life but never have been privy to witness a boiler system.
The tank is designed to accommodate fluctuations in the volume of a buildings hot water supply system. Essentially for the heating and cooling of the water.
The water heater inspected appeared to be near brand new by it’s condition, which was further verified by the label, which shows the manufacture date and ratings for the appliance, as was as fuel type and capacity. in this case a natural gas fired unit, there is a TPR valve, however, no drop was attached to it.
It is important to be aware of different installation areas of water heaters and the code rules that differ between areas such as basements, confined spaces and garages. Depending on the fuel type, certain installations may or may not be allowed.
This photo depicts the natural gas supply connection to a 50 gallon gas fired water heater. The most obvious defect is the absence of a drip leg. This installation could allow debris and moisture from inside the gas line to possibly clog the gas valve or burners. The second defect is the use of a galvanized reducer. Galvanized pipe and or fittings should not be used.
This is a water heater that is in an unfinished basement. The TPR valve is located on the side of the tank and has the proper discharge piping running down about 6 inches above the floor, it discharges into a proper drain.
I read the article on water stoves. Also known as outdoor wood furnaces, the main goal of a water stove is to burn wood to create heat which heats the water in the pipes that circulate around the house. As the heated water is circulated around these pipe the heat is distributed around the house.
This is a picture of a 40 gallon electric water heater. Installed in a utility room with a home made pan. The pan is routed through the outside wall with a visible termination. The tpr valve is also routed to the outside with an appropriate size and type of discharge pipe.
Essay on 15 Tools for Homeowners
This article lists a very good starter set of basic tools for the homeowner. I would also include a good pair of gloves. One tool that I would also include is a painters 5-in-1 tool. It is handy for an amazing range of uses, few of which have anything to do with painting.
I read the articles about attic pull down ladder. Reading the proper way that is should be installed. What should and should not be cut to install a ladder for attic access. With hands on training I notice a lot of improper attic ladders.
Looked at an water heater. Custom blanket was covering label. No expansion tank. TPR Valve out went threw floor to crawlspace below. Items stored on and near the water heater. Water Heater was located in the Utility room with washer and dryer.
The subject of my essay is formaldehyde as used in home building and furnishings. Formaldehyde when mixed with other chemicals is used as a glue or bonding agent. This bonding agent is found in many sheet products such as paneling and particle board. When subjected to higher temperatures or high humidity levels it will gas off. The fumes can cause many physical ailments, and is suspected to cause cancer.
The importance of TPR Valve inspection on a hot water heater can not be understated, as an inoperable valve can cause extreme pressure build up within the tank, potentially creating a projectile should the tank rupture. Any leaking and or corrosion should be reported.
