South Fork baseball falls to Credo in title game

first_imgWith their backs against the wall for the majority of Saturday’s North Coast Section Division-VI championship game, the Cubs continued to fight.But after four innings the No. 1 seeded South Fork High baseball team ran out of steam, relenting a slough of runs in the final few innings to No. 2 Credo — Rohnert Park before falling 8-3 in the section title game Saturday afternoon at South Fork High.“We finished second in league — came very close to splitting it — and second in the NCS, so overall …last_img read more

The Case of the Mystery Gas Leak

first_imgTest the gas linesDavid Meiland suggests going directly to a gas-line test rather than spending any more time doing spot checks around gas-burning appliances with a gas sniffer.His two-pronged plan of attack starts with disconnecting all of the appliances from the piping and installing caps in place of connectors. Disconnect the meter, install a test cap with a pressure gauge, he says, and pressurize the piping to see how the gauge behaves.“It should be possible for the piping to hold pressure with no drop for a long period,” Meiland says.The second step would be to reconnect the system and fill the lines with gas. Attach a manometer to one of the appliance shutoff valves, he says, and watch for a pressure drop. He recommends a qualified gas plumber perform both tests.“I don’t see the point of sniffing any more,” Meiland writs. “A possible gas leak needs to be ruled out using pressure. A sniffer (I have one…) is a useful tool for finding leaks, but it isn’t the same thing as pressurizing and making sure that pressure is held. Without doing that you are not going to be sure.” Our expert’s opinionHere’s how GBA technical director Peter Yost viewed this issue:It seems as though others, particularly our own GBAdvisor master builder and plumber, Michael Chandler, have given great guidance on the mysterious gas odor and leak.On the air tightness of a new home, I just wanted to add these two perspectives, one on the qualitative side of blower-door test results, and one on the quantitative side.Qualitative blower door testing: I have seen blower door tests done where there is a rush to get the CFM50 number and be done, missing the opportunity to dial back to -25 Pa, and go around and look for the big leaks with a smoke stick and/or an infrared camera. The how and where of the leaks is just as important as — if not more important than — the actual -50 Pa result.Quantitative blower door testing: On the other hand, I have seen the rush to the CFM50 single-point result miss the information you can get with the multi-point regression curve. That little exponent can have quite a bit of information packed into it.Quoted from the US Army Corps of Engineers Air Leakage Test Protocol For Measuring Air Leakage In Buildings, page 13: “In general, an n value closer to 0.5 indicates large holes that are much shorter in length than they are wide, where an n value above 0.65 indicates the hole characteristics that are smaller cracks or holes that are much longer than they are wide. Most ‘tight’ residential homes exhibit an n value of 0.60 to 0.65, where larger buildings will likely have an n value slightly less.” This puzzle is the topic of this week’s Q&A Spotlight. What began as an attempt to track down the source of air leaks in his one-year-old home has [no-glossary]led[/no-glossary] Kevin Hilton to a deeper mystery — a natural gas odor that is apparent only when energy auditors are running a blower-door test.As Hilton explains in a Q&A post at GreenBuildingAdvisor, the source of the gas leak has been impossible to track down so far.“During the blower door test run at 50 Pa, I began smelling natural gas,” Hilton writes. “The test was immediately stopped and the smell dissipated. The natural gas hand-held detectors were unsuccessful in detecting a leak with the blower door turned off. The operators then turned the blower door back to 25 Pa, and behind one of the walls the detectors isolated the area of the leak.“The problem, however, is that there are no gas lines located behind this particular wall where the leak was detected.”The plumber who installed the gas lines said he couldn’t detect any leaks with his equipment.“What do I do now?” Hilton asks. “It seems like the natural gas leak is only detectable with the blower door in place and operating. I am concerned since based on the results of the audit I believe I am going to spray foam the attic and turn it into a conditioned space. I don’t want to create a closed envelope with combustion hazard.” RELATED MULTIMEDIA Attic Air-Sealing: Products and Materials Overview RELATED ARTICLES Pinpointing Leaks With a Fog Machine New Air Sealing Requirements in the International Residential CodeQuestions and Answers about Air Barriers Maybe it’s not the lines at allSenior editor Martin Holladay suggests that Hilton may be smelling something other than natural gas. “Many things can smell like natural gas,” he notes, “including a decomposing dead animal.”J Chesnut agrees with Holladay that the “natural gas leak” may be something else entirely. “My bet is while you are depressurizing the house sewer gas is entering the house through the basement floor drain,” Chesnut writes. “Check to make sure all your plumbing drains have appropriate traps and make sure they are filled with water.”Michael Chandler agrees, and outlines this strategy: “Drive to the grocery store with an empty coffee can in your car,” Chandler says. “Buy four little bottles of peppermint extract from the bakery section. Place them un-opened in the coffee can and rest it between the truck motor and the hood so they get nice and warm as you drive home.“Without entering the house climb up on the roof and pour all that peppermint down the sewer vent. You will now smell like a Christmas cookie so have someone else sniff around inside the house for peppermint smell; run blower door or range hood as required. Replace wax gasket at base of toilet that smells like Christmas.“Been there, done this,” he says, “it’s why my hair is this impressive shade of gray and so thin on top where I pull on it.”Meiland has seen a similar situation with a client whose house started to smell after the septic tank was pumped. Turns out, removing the solid layer on top of the tank allowed sewer gases to enter the house through an uncapped pipe left in the wall.To find the source, Meiland used a bath fan to push smoke down through a vent on the roof and traced it from there. Let’s not forget the original problemAs Hilton scrambles to discover a potential safety hazard in his house, it’s easy to overlook the fact that it all began with an effort to find and remedy air leaks. The solution to the gas leak may turn out to be relatively simple, but correcting “massive” air leaks in a new house won’t be so easy.The builder tells Hilton that he met all code requirements and was given the green light by the local inspector.“The cost for me to remove the blown-in insulation and spray foam the underneath side of the roof deck is estimated to cost me anywhere from $25K to $40K depending on the company, the type of foam (open-cell or closed-cell), the amount of drywall that needs to be removed to access certain areas of the attic, etc.” Hilton writes. “The builder has informed me that if I choose to go this route, I’m responsible for all the costs associated with this intervention.”As GBA senior editor Martin Holladay points out, the 2009 IRC toughened air-sealing requirements. Whether Hilton’s builder actually met code requirements would have depended on what was in effect at the time locally.last_img read more

10 Sikkim Democratic Front MLAs join BJP

first_imgTen MLAs of the Sikkim Democratic Front (SDF) joined the BJP on Tuesday, making the latter the main Opposition party in the Sikkim, where it failed to win a single seat in the recent Assembly polls. The MLAs joined the BJP in the presence of its national general secretary Ram Madhav, who is in-charge of the party’s affairs in the northeast, and later met party working president J.P. Nadda.Mr. Madhav told reporters that the SDF had a strength of 13 MLAs and its legislature party had decided to merge with the BJP.The BJP is running governments as the main party or in alliance with regional parties in all the northeastern States except Sikkim. With this development, the BJP will become the principal Opposition party in Sikkim.The party won 15 seats while its rival, the Sikkim Krantikari Morcha (SKM), won 17 in the 32-member Assembly. Since two of the SDF MLAs had won from two seats, they resigned from one seat each, reducing the party’s strength to 13 in the House. The SDF was an NDA ally, but now the SKM has replaced it as a member of the BJP-headed North East Democratic Alliance.The MLAs who joined the BJP include Dorjee Tshering Lepcha, who has served as a Minister thrice in the Chamling government and is a five-term MLA, and three-term MLA Ugen Gyatso.Lone rangerThe SDF tried to put up a brave front saying that people of Sikkim were not used to national parties and one had to wait and watch to see how far this “new experiment” went.The SDF is now left with only one MLA —Mr. Chamling himself. “We are certainly facing the most challenging times,” SDF spokesperson P.D. Rai told The Hindu.(With inputs from Shiv Sahay Singh)last_img read more
