Add a U-bend to the pipe. You'll have to cut out the bad section, then add 90 elbows to each end. Then you can install the repair piece by slipping it into the two ends.

I got a 2005 homestead rv and the water pipe broke or froze up how can I check and fix it

Water pipes in RV are Pex, which is not the same as PVC. Pex will freeze, but is designed to not burst when frozen. If you have located the broken pipe, it is simple to replace. Using a PVC cutter (looks like cheap shears) cut out the broken piece. Most likely the pipe size will be 1/2 inch. Pex comes in three different colors: white, red, and blue. Most likely the RV pipe will be white, but the color does not matter as the pipe is of the same material. Pex can be bought at stores like Home Depot, Lowes, or other hardware stores. The connector fittings can be bought at the same stores. The simplest to use fittings are the push-on self sealing fittings. There are cheaper fittings, but they take special tools to install them. The estimated cost of a 2 foot distance pipe repair is about $10 to $15. The time required depends on how difficult it is to "get to" the broken pipe.

Well pump losing prime

you might have a leak in the foot valve, you can try installing a check valve several inches before the intake to maintain a prime, or check and clean/replace the foot valve.

If the pump ran dry, check the inlet fitting. the pump can get hot and melt pvc piping connected to it, causing air to leak in the inlet side.,

What size npt thread is the adaptor

Common American National Standard Pipe Taper Threads
  • NPT - National Pipe Thread Taper
  • FPT - female (internal) National Pipe Taper threads
  • MPT - male (external) National Pipe Taper threads
  • NPTF - Dryseal American National Standard Taper Pipe Thread (ANSI B1.20.3)
For NPT threads a sealant compound or Teflon tape must be used for a leak-free seal. For NPTF no sealant is needed for a sealing.
Characteristics of NPT (also known as ANSI/ASME B1.20.1 Pipe Threads, General Purpose):
  • tapered thread 1o 47'
  • truncation of roots and crests are flat
  • 60o thread angle
  • pitch is measured in threads per inch
Note! Pipe sizes do not refer to any physical dimensions. The outside diameter of a pipe or fitting must be measured and compared to a table for size identification. A 3/4" NPT pipe thread has an outside diameter - OD - of 1.050 inches.
Each thread size has a defined number of threads per inch - TPI, or pitch. The 3/4" NPT pipe thread has 14 threads per inch. Both the TPI and OD of the thread are required for positive identification of thread size because more than one size have the same TPI.

NPT threads are not interchangeable with NPS - National Pipe Straight - threads.
NPT threads may look similar to ISO 7/1 threads. However, ISO and NPT threads should not be mixed. ISO threads have 55o taper angle versus 60o for NPT. The NPT root and crest configurations are also different from ISO. For ISO threads pitch is usually measured in millimeters (may be expressed in Inch). The pitch are different.

A pin hole in pvc pipe under jacuzzi what can i use

Self amalgamating tape wrapped several times around and well over lapped would probably do it. Just to be sure I would secure it in place with one or two 'jubilee' type hose clips (the sort used to secure radiator hoses on cars) would probably make a quick fix.
For a longer term repair you could try using fibreglass car body repair paste (the sort with fibres in it - not the smooth filler paste). However it will not still to pvc very well. The surface needs to be rubbed with a bit of glass paper to roughen it slightly and then degrease by wiping with a cloth moistened with acetone (nail polish remover would do) before fibre-glassing.

I want to connect a single phase 24 amp kiln under my waterproved pergola. What electrical work needs to be done and how much would it cost approxmatly?

That kiln requires a 30 amp circuit, minimum. 24 amps x 125%= 30 amps per National Electric Code (NEC).

Without more info, I'll need to make a few assumptions. For the sake of estimating the cost I'll present the following scenario:

1...The distance from your electric panel to the pergola is approximately 100 feet.

2...The circuit will be underground. I'll assume that you will be able to hire someone to dig an 18 inch deep trench from the electric panel to the pergoda for $10 hr. While this should only take 3 or 4 hrs, depending on soil conditions, it could take all day. So I'll assume $80 for this.

3...This will be a 240 volt, 30 amp circuit (see why below).

4...Since you posted under the Intermatic T171, and since that is a 120 volt timer, that the kiln is 120 volts.

5...Unless the pergoda is fully enclosed, NEC still requires a weatherproof installation.

For starters, I don't recommend a 120 volt kiln. Most people I've known who had a kiln always seemed to want a bigger one ;-) Again, I'll do the estimate for a 240 volt, 30 amp kiln, as the price difference compared to a 120 volt circuit is about the same.

Also, I strongly recommend using 3/4 inch PVC conduit as opposed to 1/2 inch PVC or UF (direct burial) cable. 3/4 inch conduit doesn't cost much more than 1/2 conduit and will allow you to install wire up to #6. UF cable, in my opinion, is out of the question because if you ever decide that you want a larger kiln the direct buried UF cable is _not_ easily replaceable. A conduit and wire installation is about the same price as UF anyway.

Here's the breakdown (US dollars):

$ 10 - 30 amp, 2-pole circuit breaker
120 - 300 feet of #10 THWN COPPER wire (40 cents a foot)
20 - 1 bundle (100 feet) 3/4 inch PVC conduit
10 - 3/4 inch PVC elbows, fittings, straps
20 - Weatherproof box and weatherproof cover
+15 - 30 amp receptacle
+100 - 2 hrs labor @ $50 hr. (possibly 3 hrs.)
+80 - labor for trench
+140 - Intermatic T172R (weatherproof) 240 volt timer

Other considerations are that, if indeed, the circuit is 100 feet, you should consider using a #8 THWN COPPER wire to account for voltage drop (add $60, @ 60 cents a foot) Using a #10 wire at that distance may not allow the kiln to get to the desired temperature.

If you are anticipating things like lights, 120 volt receptacles, fans and such, the best way to do all that is to install a subpanel at the pergoda.

That should get you in the ball park as far as price. Of course, you can make adjustments accordingly. Remember that prices can vary greatly depending upon geographic location. Also, if you call a contractor for an estimate, _after_ they give you the price, _then_ ask how much they will knock off if you dig the trench.

A contractor price of $600 would not be unreasonable.

Hope this helps.

My 1042 Power Humidifier has water under the PVC pipe leading from the unit into the drain. Does that mean the unit itself is leaking water?

Hi, if the unit is leaking and it looks as though it is coming from the PVC pipe, more then likely its leaking at the unit its self where the pipe connects. Water will run down the pipe and drip down line. Dry it off and put your hand around where the PVC pipe screws into unit. Unless the pipe is cracked, this is where the leak is. If the fitting is a male or female threaded PVC fitting and a piece of PVC pipe that goes to the drain, you can repair this very easy. Just cut the pipe near the fitting with a hacksaw. Unscrew the fitting that goes to unit. Go to a hardware store like Home Depot, take the old fitting with you and buy a replacement. Buy a coupling, a small can of clear PVC glue and a small can or tube of pipe dope to put on the fitting threads. Screw the fitting in first and make sure it has pipe dope on it, get it tight with pliers. Take the pipe and coupling and glue it on the pipe. Put glue on the other end and slide it in the fitting that was where it was leaking before. Hold it in place for a few seconds. Once you put the glue on, be ready to put it together as it drys super fast and you cant take it apart once it sets. Very easy to repair and the parts cost pennys. Keep me posted. You can do this and will learn about plumbing! Good Luck.

How do you put this net together? i got it at a

  • Step 1
  • Attach two 8-foot PVC pipes to one of the 12-foot PVC pipes using two elbow fittings and PVC cement. The result will be a short U shape.
  • Step 2 Attach the remaining three 12-foot PVC pipes together using two elbow fittings and PVC cement. The result will be a tall U shape.
  • Step 3 Attach the two U-shaped assemblies together using two elbow fittings and PVC cement. The short U shape is the horizontal base; the tall U shape is the upright frame. The finished result will resemble a bookend
  • Step 4 Cut strips of poultry netting and stretch them across the frame, fastening them with nylon cable ties. You'll find poultry netting packaged in rolls that are 3 feet in width. Cut lengths of the netting to stretch horizontally across the frame, leaving them in the standard width. Start at the top and work down along the back of the tall frame, creating a netted pocket. Overlap the strips by about 8 inches.
  • Step 5 Position the net so that no houses, automobiles or high-traffic areas are behind it. Errant balls can be unpredictable and dangerous.
  • Step 6 Secure the net by placing one 50-lb bag of sand on top of each leg of the practice net's base.

    I have just bought a greenhouse and wpuld like to plumb water to it. The greenhouse is located 50 feet from my residence. I want to bury a line to the greenhouse but im not sure what kind of pipe i should...

    The simplest installation would be CPVC pipe. PVC would be okay for cold water only, but don't believe you can buy PVC faucets, etc. (only CPVC).

    The depth should be below the frost line for your region -- I looked for that, but it wasn't easily found. My guess is it's in the range of 4-5 feet.
    But you should verify that, maybe thru the local building inspection agency.

    No pipe (expandable or not) is going to be immune to freezing/bursting unless it's below the frost line.

    If you drain/blowout the entire leg during the winter, it doesn't matter how deep you bury it. If there's no water in the line, it won't burst.
