Q:My friend and I covered (brushed) his rolled roofing (1 layer) with Black Jack fibered roof coating (black). His roof is flat with a 15 degree slope top to bottom. His roof had leaks and it rained 2 days before we covered the roof. The roof felt dry when we started. The temperature range has been 45-85 with some dew in the morning. It has been a couple of days and the covering is blisteringsmall blisters that just seem to contain air. Is it possible moisture from below the roof surface trying to escape? It had been dry for a month before the day of rain that preceded our project, and dry since. Is it the morning dew causing a problem? Most important, is it ruined, or can we roll out the blisters with a rubber roller or something? I'm wondering how long the coating takes to cure as well, as it seems a bit soft to walk on. Any suggestions would be appreciated.: Yes, the pipe threads are the same However - The 40 80 refer to what water pressure the pipes and fittings are designed to handle - 40 psi 80 psi. That's why the pipe wall on sch 80 is thicker. Mixing the two is a bad idea. You'll either waste money buying heavy-duty sch 80 for a system that stays within the 40 psi limit of of the lighter pipe, or you'll waste money and time replacing the lighter parts when they blow out at the higher pressure.

Q:if you answer i don't need the typical gith clothes are not cheap i know that i just need an answer for my question.all my clothes are so worned (sorry for my english) and i have nothing to wear i am not in the best possition to buy clothes right now but i need something to wear and because in my country we don't have many cheap goth stores i buy online.in the moment i need something cheap. please do NOT answer if you can't answer my question thank you and sorry for being rudep.s something like that: may be gas pipe if in attic, better let a pro do this on. Normally water pipes are in ground, crawl spaces, or in between floors.

Q:I've a dishwashing job at a restaurant, I don't like to wear those annoying rubber gloves that make my hands sweat. Is it really necessary to wear gloves?: If you use 1 1/4 pipe schedule 40 and keep it under 48 you should be able to hang about 50 or so pounds on the pipe. If you go past that, it will sag pretty badly. Be sure to draw out what you want to build so you get an accurate idea of what types of fittings you will need. And above all, dry fit it first to make sure it works before you start gluing it together.

Q:do they remove the tooth? will he be able to drive back? Will he be able to talk immediately after it? thanks: Yes, I have the problem where I get up, turn off the alarm, and go back to sleep, thus being late.. LOL. What you should do is get multiple alarm clocks and set them to go off at the same time. That way you have to force yourself to get up and shut off all the alarms. By the time you're done you will be out of that haze.

Q:Can someone translate this to english (from korean)?: Burst implies a domestic water pipe, hot or cold, so the answer will be based on that implication. Determine the size of the pipe. Likely it will be either 1/2 or 3/4, likely copper. Determine the extent of the burst. If from a freeze, likely it will be a split along the length of the pipe, anything from a few inches to (rarely) over a foot. Go to your local big-box store and purchase a length of PEX of the appropriate size that is at least six inches longer than the damaged area. PEX usually comes in short pre-cut lengths or in a 100' or 200' roll. A pre-cut length will do it in most case. Purchase two Shark-Bite couplings to match. If you do not have a pipe-cutter, for what you will save from calling a plumber, you can afford to buy one, and a good one at that. The PEX can be cut with a sharp kitchen knife. Cut out the bad section + a little bit from each end - 3 or so. Cut the PEX to match the gap, less about 1/2 on either side. Install the fittings - left end fitting to copper; PEX; right end fitting to PEX; fitting to copper. Be sure to bottom the fittings as you go. Less than $40 including a Ridgid pipe cutter. Less than $20 otherwise. It is not rocket science, all you need is patience and a little bit of hand-strength. Ask the person in the store to show you how to use the cutter, and even how to use the fittings. Once you learn, you will be prepared for the next time. NOTE: If you use a hack-saw to cut the pipe ILO a tubing cutter, be sure to cut slowly and not force the pipe out-of-round. Cut all the way through - don't be tempted to break off the last bit. Clean the rough edges with a file and get the marl (cutting waste) out as best you can. In either case, when you turn the water back on, run a hose or tub fixture for at least a minute to get any displaced particles out. Good luck with it.

Q:Can you tell me the difference between the half pipe joint and the branch seat?: The 2. branch pipe seat is widely used abroad in recent years, the branch for strengthening pipe connection, to replace the traditional use of different diameter three, reinforcing plate, strengthening pipe etc. branch connection type, which has the advantages of safety, lower cost, simple construction, improve media channel, standardization, series design has the advantages of convenient so, especially in high pressure, high temperature, large diameter and thick wall pipe is widely used, instead of the traditional branch connection method

Q:does anybody know a great place online to buy motorcycle or moped alarms?TIA,Luke: galvanized pipe means just that it is coated with galvanize to help keep it from rusting. blk pipe has no coating inside and a blk finish outside, normally used for natural gas piping installations. wall thickness is either schedule 40, or 80. 40 is the standard 80 is a much thicker wall used for high pressure applications. the 1inch pipe and the 1inch nipples are the same wall thickness. the threads on both all taper inwards. by drilling a hole in galvanized pipe you will expose the inside wall of the hole to water,gas,oil, or what ever you are using the piping syatem for. therefore you are defeating the porpous of the galvanizd coating. hope this helped

Q:A giant one foot rubberband would work too: If your daughter has started to curse at you then it usually means that she has little respect for you and she finds you to be a push over and she thinks she has the control. If you let her get away with it then it will only get worse. You have to show her that you have the power, but at the same time try showing her that the two of you could get along and it doesnt always have to be fighting. If going to her fathers house is making it worse, then have a serious talk with the father and get him to set some standards for your daughter, but if he wont do that then you will have to set more standards for you daughter. But you also have to make sure your daughter doesnt take it the wrong way. Some times when parents take to many things away and restrict their children to much, the children rebel even more and do even worse things. good luck and i'm sure it will all work out for you.

Q:Do you have DN150-DN80 variable diameter steel pipe joint?: Such components generally belong to standard parts, which is a national standard. It's easy to procure in the market.See details: "GB/T 12459-2005 steel welded seamless pipe fittings"The L length of DN150-DN80 is 140mm, and is H in the national standardSee below:

Q:I want to stand a 9' copper column on my patio for decor. It will only be 8' from the house. i dont want it to be a lightning rod, any tips or references would be appreciated. Thanks.: it only comes in blue, red, white, and black. try a plumbing supply store.
