Teflon Seal Does every joint of a p-trap need to have a compression seal?
I installed a new sink that's not draining properly - waiter backs up into the sink instead of flowing through the p-trap and into the waste pipe in the wall. There's no blockage in the trap. I had to use an adapter to connect the p-trap to the wall - i'm wondering if every connection from the sink to the wall needs to be sealed with a compression nut, teflon tape, or caulk, perhaps to keep the pressure in the pipes such that water flows out. Is this the case?
What type adapter did you use? Is this the only difference in how the old piping was arranged? What size pipe, and what type material is the pipe protruding from the wall? I suspect that this is where your problem lies! Water drains by gravity, but it needs a vent, in order to drain properly. You might have stuck the drain pipe too far into the wall, just as the previous person said. If that is the case, disconnect and shorten the pipe that attaches to the wall pipe. Good luck!

It's not often the word revolutionary can be associated with duct tape, that old, sticky standby used in plumbing repairs, hockey stick augmentation, and homeland security protection. By getting the gray out--and avoiding the "sore thumb" look of typical duct tape repairs--3M's Scotch Transparent Duct Tape can indeed lay claim to a revolution of the toolbox...
Teflon (poly-trafluoroethylene or PTFE) earned it's stripes as a highly effective and reliable thread sealant when it was used during the Manhattan Project to seal pipes carrying radioactive material. More recently, it's been incorporated into the manufacturing process of the waterproof fabric Gore-Tex(TM)...

Hydrogen Sulfide H2S is a main source of sulfur. In high concentrations it can be lethal. It occurs in natural gas, oil, volcanic emissions, and some mineral springs. In oil rfining processes its presence is undesirable, and it must be removed. The Clause process is one of the methods used to remove the hydrogene sulphide, and while doing so, recover elementar sulfur.
Canada Blower Co. now offers gas-tight and zero leakage steam-jacketed blowers for Sulfur Recovery in Cemical Industry.
In pactice this sulfur removal process requires a gas-tight, zero leakage, high temperature and high pressure blower for intermittent duty that must handle toxic gases and must be capable of being brought on line immediately upon demand. To do this the following features on the blower must be provided:
- Double welded casing construction; - Steam flows between the housing walls to maintain a constant 285 F gas temperature inside the fan (because below 285 F sulfur will change from a gaseous to a solid state and will "freeze" to the blower surfaces causing damage or destruction); - A mechanical shaft seal with heat tracing and purge by air or nitrogen; - To assure tight tolerances between the shaft and shaft seal, the housing should be supported at the centerline, and grows concentric to the fan shaft when exposed to heat.: since this support isolates housing from the drive and mounting bases, housing thermal growth doesn't cause forces to be applied to these bases. - To prevent the shaft from taking a permanent set when the blower is idle but still exposed to the high temperature, a turning gear is provided to keep the blower rotating at a very slow speed of 25 - 40 RPM; alternatively a VFD speed control can be used
Steam jacketed construction can also be used in other thermally critical chemical processes. As to air-tifgt and zero-emission construction, it is used in the following industries:
* Pollution Control * Pulp and Paper Industry * Printing and Converting * Chemical Plants * Power Generation * Research and Development * Petroleum * Food Processing * Paint and Ink Industries
for containment of hazardous organic and inorganic compounds in industrial process plants and other critical applications. Special construction and shaft sealing devices are available for blower service requiring zero or minimal gas leakage into and out of casing.
Canada Blower has a lot of experince with gas-tight and zero-leakage construction on fans and blowers, including: multistage lip shaft seals; Buna-N, Viton and Teflon seals; mechanical shaft seals; special fan housing gasketings; single and double carbon ring seals; hermetically sealed blowers; magnetofluidic and ferrofluidic seals; and packed stuffing boxes with barrier liquids and purgeable seals.
Specific code welding processes and special fan design features are used too - to ensure complete gas tight integrity.
Some special materials and alloys frequently used in gas tight fans, especially for service in hazardous, abrasive, corrosive and high temperature environments, include:
Corten, ASTM A36 Carbon Steel, Hastelloy, Inconel, Stainless Steels of different kinds, Titanium, Monel, Aluminum, Teflon, Rubber LIning. These materials are typical for industrial applications requiring high strength alloys and super alloys too.
Canada Blower is a world wide distributor of industrial process ans OEM fans and blowers, as well as fan components; including high pressure blowers, high temperature fans, spark resistant and explosion proof ventilators, tubeaxial and vaneaxial high pressure ventilators. Canada Blower also does existing fans and blowers repairs, re-build, as well as dynamical wheels balancing.
