Your best bet would be to get some 1/2" PVC Couplings with threaded port and some Misting Nozzles. You should be able to find them both online, or at your local landscaping/gardening center. This setup would allow you to get the desired spray pattern, by selecting the appropriate nozzles.

I see no reason why you should cut threads on a PVC pipe. It seems to me that this would be unnecessarily difficult and would weaken the pipe. You should, instead, get a slip to thread adapter and glue it onto the pipe to thread it wherever you like. Any big-box hardware store or irrigation department should be able to provide this adapter.

PVC is relatively inexpensive so the main cost is installing it. If your furnace is near an exterior wall, they'll simply make a hole in that wall and run the lines directly out. If your furnace isn't close to an exterior wall, then you need to run the lines through the ceiling, preferably in the direction of the joists, until you reach an exterior wall. If ...

I highly doubt a paint store sells what you are looking for. When you join two pieces of PVC, you aren't joining them together, but welding them together. PVC Cleaner (AKA Primer) cleans all dirt, and oils off the parts and soften them a bit, so they weld together properly and the glue can penetrate the PVC deeper. The glue then works on a molecular level ...

The glass temperature (point at which it starts becoming molten) for PVC is 82°C (179°F). The generally accepted maximum operating temperature for PVC is 70°C (158°F) though again, this can vary by product. Pressure ratings are at room temperature (21°C/70°F), and they go down as the temperature goes up: at 70°C the pressure rating is decreased by around 20% ...

The schedule is the wall thickness of the pipe (essentially how much pressure it can withstand). Wikipedia has a Nominal Pipe Size Table (and the article goes into the description of the size and the why behind them). From this article http://www.ehow.com/facts_5575151_difference-between-schedule-schedule-pipe.html: For a relatively constant pipe ...

All PVC is subject to UV light degradation. PVC without UV protection will eventually suffer a loss of impact resistance. Your pipe will be whole, until impact at which it will shatter or crack instead of flex. Some PVC (PVC UVR) is UV resistant. The sunlight still damages the PVC pipe, but it is in a matrix of other chemicals that compete for the UV ...

Is it expensive? Well that depends on your definition of "expensive", the amount of work you need to do, and who you get to do the work. 90% efficient furnaces require PVC venting directly outside, as opposed to using a chimney like the older 80% furnaces do. The extra expense is entirely dependent on how easy it is to route these pipes from your furnace to ...

In these situations, I use bulkhead fittings. It saves the annoyance to getting this stuff to seal properly, any slight leverage and there's now a leak. These are available in several sizes at most plumbing supply stores. If there's a gentle curve to the surface this has to penetrate, I've used a large O-ring instead of the supplied gasket. They're available ...

PVC is not rated for and not safe for compressed air service, with the limited exceptions of "if buried in the ground or completely screened in wire mesh to catch the shards." It makes lovely shrapnel - it has injured people. Nice and cheap until it costs you something more dear than money. Here's a 480 PSI (water, not air - no PVC is made or rated for ...

It sounds like you're using a crappy copper pipe cutter. To cut PVC, you want one of these instead: I've used mine to cut thousands of PVC pipes and it does the job quickly and easily. You can probably find one for less than $10 and it will serve you well for life.

I have the same setup, and this appears to be the industry standard for high efficiency gas furnaces. What I have done is take a piece of plastic screen, and hose clamped it over the end due to a couple of 5 year old hooligans that run around my back yard and find such outlets very attractive for the experimental dropping of pebbles and other small items. ...

No, any extra water (from snowflakes and rain) that run down the exhaust will drain out with the condensate. However, if the furnace is off in the summer, might want to have a removeable end cap to keep the bugs, bees, wasps, etc. from nesting and also prevent children from sticking a hose down the pipe. A little water is OK, little Johnny playing ...

I don't have an adhesive suggestion for you, but you could use hose clamps. Put one on the top and one on the bottom of a rectangular section of velcro and clamp it onto the pipe. (Make sure to not over-tighten it.) Actually, if you could work up a way to attach the fabric to the hose clamps and skip the velcro altogether, that would cut your hose clamp ...

You can purchase a toilet flange repair at any big box hardware store. Remove the wax ring (buy a new one), remove the bolts, and mount this on top of the existing broken flange: Then reattach the toilet as per normal, making sure not to over tighten. Tip, seat the toilet firmly on the wax ring before you tighten the bolts, and use a STANDARD sized wax ...

If the windows are no longer sealing correctly, replacing the weather stripping is the easiest method to close drafts. If the window is crooked (measure to make sure it's square and level) but it's otherwise working fine (opens and closes with ease, and the crookedness is not visible or bothersome) then you can apply additional weather stripping to the ...

It's not PVC, it's either PB or PEX, which are sized similar to copper tubing. They normally are connected with barbed fittings with compression rings but compression fittings with metal inserts also can be used.

Take up the flooring and install proper joists to be 8" on center. At 12" on center your diagonal distance would have been just under 17". Now with 16" on center your diagonal distance is 22.6". That's way too long, and of course it's going to pull and squeak. I'd be worried about long term safety as well. Manufacturers do give recommended maximum ...

The hose clamp is right out. All you'll do is crack something -- if you're lucky, right away. Likewise trying to inject PVC cement (705) is not a good idea. Even if you manage to plug the leaks, the majority of the joint is compromised. It will eventually fail, and the law practically says it will fail 2 hours after you've left for a 2 week vacation, ...

You've already accepted, but to properly fix this: I'll assume it's all polyethylene pipe (typically used for well piping). The fitting also looks like nylon, which in my experience is easy to damage and often leaks. I much prefer PVC (which is typically gray) or brass. Take everything apart, remove the elbow, and throw it away. Heat the end of the poly ...

You can try a fiberglass "pipe repair kit" available at most hardware stores. You soak the fiberglass in water which activates the resin, and then wrap it around the leaking pipes. It will completely encase the pipes and harden, leaving you with a pretty strong temporary fix. I've used this on PVC and copper with good results; I think it would work on rubber ...

The lucklihood is that it will reduce the pressure throughout the house significantly, especially if more than one faucet is running at once. It is also possible that the softener might not work correclty due to the reduced pressure, or that the output pressure will be even less than expected. I would think that hard water for a couple extra days would ...

You could try the gray colored Schedule 80 PVC pipe. This is a much heavier duty material that will stand up to being outdoors. It is recommended by manufacturers. such as U.S. Plastic Corp, that PVC pipe and fittings be painted after installation with a coat of white water based latex paint to provide for UV resistance. The UV light is what is part of the ...

The best lubrication I've found is some good ol' Elbow Grease™. Actually, you should measure the proper lengths and just cut. Then glue it up and install. You can mark on the PVC how far it should go into the fitting if you want to be really precise. However PVC itself expands and contracts a lot with temperature change and is fairly flexible anyway. So, ...

Gorilla glue makes a non-toxic PVC glue.

I wouldn't use the PVC pipe at all. Here are some things to think about... 1) Splitting the PVC pipe in half will involve two saw kerfs that will make the re-mated halves not restore to original size. 2) PVC cement will not work well in trying to re-join the two pipe halves. That type of cement is meant to be used in tight lap type joints; not in rough ...

Although I'm not convinced a round hole of any size will give you the misting mattern you are looking for, micro-sized drill bits and an accompanying hand tool (pin-vise) are actually not that expensive, and will last you a long time (if not abused ;) ). For ~$20 you can get a pin-vise and micro bits from many hobby shops (real or on-line). ...

You have two choices depending on whether you have continuous areas of plants to water or discrete plants to water. For the latter, you would use drip emitters, bubblers or misters like these: http://www.rainbird.com/landscape/products/dripEmission/XeriBugEmitters.htm http://www.rainbird.com/landscape/products/dripEmission/XeriBubblers.htm ...

Yes, you could use 3" PVC schedule 40 pipe such as This one from The Home Depot. Cut it to length, then cut it lengthwise on one side and use duct tape to hold it together... This single cut will keep the round shape and when it has set, it will give you the ability to flex the pipe enough to have your cast come out. I would not use a PVC end-cap, but I ...

Paint primer that says it's suitable for PVC can be used for painting PVC siding, Vinyl window surfaces, fencing, etc. It is a paint primary coat for weatherproofing surfaces and enabling other paint coats to stick to the plastic so they don't peel, not a pipe assembly agent. See Gunner's comments for proper materials needed for pipe assembly. it's a whole ...
