CULTURAL QA 06-2023-24A Q1 How do plumbers find water leaks inwalls?
A1 Ed Sirett, Heating Engineer, Rental property manager, EV☺2y I'll give you anexample: Tenant is saying that one of the bedrooms has a damp wall,it's the sort of thing that ends up in my ‘in tray’. So I take a look,yes it’s the wall that backs against the bathroom. The bathroom has the shower,shower mixer, basin and WC all on the other side. It's all tiled in the bathroom. The wall is a brickinternal wall about 120 years old. I look carefully at the bedroom wall theemulsion paint is blistering, there is a general sense of damp. I mark thelimits of where the damp has reached. I also see that the damp only goes up to about 1.3m abovethe floor. Now I reckon themiddle of the damp pretty much coincides with the shower. Damp in my experiencewill not travel very far upwards so the top of the damp won't be much above thesource, and that confirmsthe height corresponds to the mixer valve, a concealed type behind a smallcover plate. Plate comes offand the hole in the brick work is wet. I thought Ibetter investigate further and after some disconnection andexamination, the leaking fitting is found. Root of the problem was a low costcrew (the go to choice for that particular landlord), who had failed to makethe recess in the wall deep enough for the pipe work. As a consequence the connection leaked.It was a particular design of a push-fit fitting which requires the pipe tomove a couple of mm backward from the fitting to form a reliable seal. Themovement was not available and the leak was a drop every second or two. Tookabout 2 months to dry out in summer. Essentially findthe epi-centre of the evidence of leakage, find the highest point of leakage. Xmarks the spot. Q2 How do plumbing professionals findleaks? A2 Clif Beam, Master Plumber at MultipleCompanies (2010–present)2y Plumber here. Water leaks are found inseveral ways. The first and most obvious is to look for a puddle ofstanding water, then visually looking around above it to find the leak. The 2nd isto turn off all the fixture valves so no water is flowing,then watch the water meter for activity. The 3rd is to shutthe water off at the meter, install a pressure guage so that whether on the system, fill the systemup with water/air and see if the pressure drops. If the pressuredrops (indicating a leak), the entire system gets a visual check to look foranything obvious. If novisual leak is found and the water line runs under a concrete foundation,special sound sensitive equipment can be used to locate leaks under the slab. For gasleaks, we use compressed air and a pressure guage. The systemgets removed from the gas source (usually a gas meter) and an air guage isinstalled. All the gas valves for various appliances (stove, clothes dryer,water heater, etc are closed, then the system is pressurized with compressedair. If the pressure drops on the guage, there is a leak. Soapy water and a sponge are then sprayed on each joint in the system tocreate bubbles where the leak is. Q3 Why do you need a pop-up drain stopperin your sink? A3 Pooja Goswami, Project Manager(2018–present)Jun 19 A pop-up drain stopper is necessary in a sink for a fewimportant reasons: Water Control: The primary purpose of a pop-updrain stopper is to regulate the flow of water down the drain. By raising or lowering thestopper, you can either allow water to freely drain or prevent it from goingdown the drain, effectively stopping the sink from emptying. Hygiene and Odor Control: When the drainstopper is closed, it creates a seal that helps prevent unpleasant odors,gases, and insects from coming up through the drain.This is particularly important in bathrooms where unwanted smells can originatefrom the sewer system. WaterConservation: With a pop-up drain stopper, you have the ability to fill the sink basin with waterfor various tasks such as washing your face, shaving, or washing small items.This helps conserve water by allowing you to use only the necessary amount forthe task at hand, rather than continuously letting it flow down the drain. Sink Maintenance:The stopper also facilitates sink maintenance. When raised, it provides easyaccess to the drain, allowing you to clean it and remove any accumulateddebris. Overall, a pop-updrain stopper offers convenience, control over water flow, and hygienebenefits. It is a useful feature commonly found in sinks in both residentialand commercial settings.

My note- by providing the metal filter removing thepopup drain filter, in a very simple manner the drain outlet is 50%completed. Then why thedrain filter? Workers find it more simple. Still the pop updrain stopper is not discarded just because the filter is provided. When leaving home on vacation etc. in most homes pop up drain filter isprovided in it’s place. Q4 Does a scooter battery charge itself? A4 Mcleodproducts, Business Consultant |Digital Marketing Services | IT Guru9h Electric scootersare becoming increasingly popular as a means of transportation. They areaffordable, eco-friendly, and easy to use. One question that many people have about electricscooters is whether ornot the battery charges itself. In this article, we will explore thetopic in depth and provide you with everything you need to know about scooterbatteries. Firstly, it isimportant to understand that electric scooters are powered by a rechargeable battery.This battery stores electrical energy that is used to power the motor and allowthe scooter to move. When the battery is depleted, it needs to berecharged before the scooter can be used again. So, does the battery charge itself? Theanswer is no. Thebattery in an electric scooter does not have the ability to recharge itself.It requires an external source of power to recharge. This is typically done byplugging the scooter into an electrical outlet using a charger that is providedwith the scooter. The battery in an electric scooter is typically alithium-ion (Li-ion) battery. These batteries are known for their high energydensity, long cycle life, and low self-discharge rate.This means that they can hold a charge for a long time and can be rechargedmany times before they need to be replaced. When the battery in an electric scooter is charging, thecharger sends an electrical current through the battery.This current causes a chemical reaction inside the battery that stores energyin the form of chemical bonds. When the battery is fully charged, the chemicalreaction stops and the battery is ready to be used. It is important to note that the charging time for anelectric scooter battery can vary depending on the size of the battery and thecharger being used. Typically,it takes anywhere from 4-8 hours to fully charge an electric scooter battery. Some scootershave fast chargers that can charge the battery in as little as 2 hours. In addition tocharging time, it is also important to consider the range of the scooter. The range refers to the distance that the scooter can travel on asingle charge. The range of an electric scooter is determined by the size ofthe battery and the efficiency of the motor. A larger battery willtypically provide a longer range, while a more efficient motor will requireless energy and provide a longer range. To maximize therange of your electric scooter, it is important to follow some simpleguidelines. First, make sure that the battery is fully charged beforeusing the scooter. Second,avoid riding the scooter at full speed for extended periods of time, as thiswill drain the battery faster. Third, try toavoid steep hills and rough terrain, as this will also drain the batteryfaster. In conclusion, the battery in an electric scooter does not charge itself. It requiresan external source of power to recharge. When the battery is charging, achemical reaction stores energy in the form of chemical bonds. The chargingtime for an electric scooter battery can vary, but typically takes anywherefrom 4-8 hours. To maximize the range of your electric scooter, it is importantto follow some simple guidelines. Q5 Why are roads on mountains curvedinstead of being straight? A5 InfoSage, Professional Maven2h Roads on mountainsare curved instead of being straight for several reasons: 1. Safety: Curved roads on mountains enhance safety for vehiclestraveling at high speeds. When a vehicle is movingalong a curved road, it is performing circular motion since the road itself isan arc of a circle. In the absence of a centripetal force,the vehicle would move along tangents, making circular motion impossible.Curved roads provide the necessary centripetal force for vehicles to safelynavigate through turns without skidding. 2. Friction and Centripetal Force: The friction between the vehicle's tyres and the roadsurface generates the required centripetal force while driving on ahorizontally curved road on a mountain. The inwardinclination of mountain roads at sharp corners allows the horizontal componentof the normal reaction to provide the necessary centripetal force for thevehicle's circular motion. This inward inclination ensures that the vehicleremains on the road and does not slide outward. 3. Managing Speed: Curved roads on mountains also help manage speedeffectively. By incorporating curved sections, roaddesigners can control the speed at which vehicles traverse the mountainousterrain. The curvature forces drivers to slow down, ensuring safer navigationand reducing the risk of accidents. 4. Slope Stability: Another important factor in designing curved roads onmountains is slope stability. Straight roadswould require significant excavation and modification of the natural slope,which can lead to instability and increased risk of landslides. By followingthe natural curvature of the mountain, the road construction can work inharmony with the existing terrain, minimizing the need for extensive earthworkand reducing the impact on the mountain's stability. 5. Drainage: Curved roads also aid in effective drainage on mountainousterrain.By incorporating curves, road designers can create a slope gradient that allowsrainwater and runoff to flow naturally along the roadside, reducing the risk ofwater accumulation and erosion. My note- I have travelledin the road with 115hairpin bends to Kollimalai near Namakkal. I have also travelled through the toughest hairpin bend road from Adivaram to Kalpetta, havingonly 8/9 hair pin bends. If myinformation is correct the road from Batalagund to Kodaikkanal isthe only road with single hairpin bend at Pannaikkad. All the above QA are from Quora website on 24-06- 2023.
