Simple Ideas To Help You Understand Plumbing
The difference between taking care of your own plumbing issues and hiring outside help is incredible when it comes to your cash flow. Why not see if you can do some of the jobs yourself? Or at least become a little more knowledgeable on the subject. Here are some useful facts and tips.
Don't shrug off that trickle coming from your toilet as a small problem. Even the tiniest leak can be quite expensive in the long run as you end up wasting potentially hundreds of gallons of water. See if you can find the root of the leak, or seek out professional advice, and keep your toilet running efficiently.
To winterize a house that will sit unused during the winter months, you must completely drain all of the pipes. After turning off the main water supply, let all of the water drain from the faucets, toilets, and water heater (turn off the gas). Add a quart of antifreeze to sinks and the tub to prevent water from freezing in the drain trap.
Make sure everyone in your home knows where the main water shut off valve is and that they know how to work it. That way, if there is a water problem, anyone in your household can turn off the water, thereby reducing the chances that your home will incur major water damage.
Use a hairdryer to thaw frozen pipes, after you shut off the water to the house. A hairdryer will gently heat the pipe and thaw the ice without causing significant damage to the pipe. Shutting off the water first means that if the pipe is broken, there will be no rush of water into the house.
Clean the aerator to fix low water pressure issues that are caused by the buildup of sediment. Take the aerator off, disassemble it, and brush it clean with a little vinegar. Thoroughly rinse off the aerator, put it back together and place it back on the faucet. Clean the aerator, it might increase your water pressure.
Treating your drains every month is a great way to avoid future clogs and other problems, and it's a very simple procedure. Just run one to two gallons of hot tap water down each drain in your house.
Make sure you get a good recommendation or check the references before you hire a plumber. With good recommendations, it will assure that you are hiring an experienced plumber. If the experienced plumber is professional, he will have a fully stocked truck and be able to complete most small jobs in one visit.
During the winter, preventing frozen pipes when you here live in a small dwelling can be something good to know. Frozen pipes will not only stop your flow of water but can crack and damage pipes. By running a little water out of every faucet during the coldest parts of the day, you can avoid this.
Now you should be much more prepared when it comes to plumbing. If you thought that you were ready before, well you should now be an expert! The tips that were given should have provided you some advice that can help you get started with maintaining and fixing your own plumbing.
Can the AC filter in your home, office or local mall protect you from Covid-19?
When New York Governor Andrew Cuomo announced last week that malls in New York could not reopen until they installed high-efficiency particulate air filters capable of trapping the virus that causes Covid-19, Harvard environmental health researcher Joseph Gardner Allen was thrilled.
"I've been writing consistently since early February about how healthy buildings should be the first line of defense against the novel coronavirus," said Allen, who directs the Healthy Buildings program at the Harvard T.H. Chan School of Public Health.
"I'm really grateful that we have a leader in the country -- somewhere -- who was finally talking about healthy buildings, ventilation and filtration," Allen said. "That hasn't happened before. It just hasn't happened."
A push to action
Allen was one of 239 scientists who wrote an open letter to the World Health Organization, the US Centers for Disease Control and Prevention and other health agencies, asking for a change in their guidance to the public on how the novel coronavirus, or SARS-CoV-2, can spread.
Current guidance only focuses on "hand washing, maintaining social distancing, and droplet precautions," according to the letter, published Monday in the journal Clinical Infectious Diseases.
The health agencies are ignoring the tiny droplets of virus that sputter and spray from our mouths, become aerosolized and then float away into the air, the scientists said, as a likely means of transmission.
"They don't want to talk about airborne transmission because that is going to make people afraid," co-author Donald Milton, a professor of environmental health at the University of Maryland, told CNN in a prior interview.
"The best vaccine against fear is knowledge and empowering people to take care of themselves," Milton said. "Why wearing a mask is important is because it blocks the aerosols at their source, when it is easy to block them."
MERV ratings
In his edict to New York mall owners, Cuomo was talking about HEPA filters, which have the highest MERV ratings, between 17 and 20.
What's MERV? It stands for "minimum efficiency reporting value," and it's how filters are rated in their ability to trap tiny particles. The MERV ratings go from one to 20: Filters with higher MERV ratings are more effective than filters with lower ratings.
At the highest end, HEPA filters are used by hospitals to create sterile rooms for surgeries and to control infectious diseases, and are able to remove 99.97% of dust, pollen, mold, bacteria and other airborne particles with a size as small as 0.3 microns. For comparison, Covid-19 is thought to be between 0.06 to 1.4 microns.
"Filters are rated at their worst performance, so 99.97% is the worst it will do," Allen said. "And that's rated for a particle size of 0.3 microns, but smaller and larger it actually does better. So the point is that it's capturing nearly all particles."
Unfortunately, most businesses and home owners may find it difficult to retrofit their existing system to accommodate a HEPA filter, or any filter higher than the rating recommended by the system's manufacturer.
Doing so can actually impair the system's performance: Smaller pores in HEPA air filters make it more difficult for it to push air. Using denser filters can affect the efficiency of the unit and strain the fan, while decreasing indoor air quality -- the opposite of what you desire.
"HEPA filtration is not always going to be feasible or practical," Allen said. "But there are other filters that can do the job. What is recommended now by the standard setting body for HVAC is a MERV 13 filter."
High-efficiency filters in the 13-to-16 MERV range are often used in hospitals, nursing homes, research labs and other places where filtration is important.
