I am looking to purchase a 1'' RTO drop pipe pitless adapter

I am looking to purchase an RTO drop pipe pitless adapter. What are the major problems with these units? I do not want an adapter that does not separate; that would be too much work to replace anything within the line/pump/other adapters

If you need instructions on current set-up you have please describe it as best you can. If your looking for an easy set-up and can get to lines fairly easy, just buy a 1/2" pipe nipple and remove water line fittings from tank and join them together . That's a by-pass.

I am not in this field, but when I saw it done, there was a cable that attached to that arm. Maybe the cable fell into the casing. See if there is anything attached. The cable is then pulled/jerked hard upward to release the arm.

I am living in Argentina I buy a Melnor Yardworks model 59-7470-0 in Canadian Tires in Canada Unfortunly the treads conectos are of difernt that we have commoly here for example Gardena and others...


This is not going to be an easy 1:1 conversion
I believe Argentina uses BSP British Standard Pipe
Unknown what thread is used for water hose in Argentina.
US sold products use NPT tapered pipe thread
US has different-but-similar thread for water hose.

So you need at least 2 adapters:
Adapter from 3/4" BSP to 3/4" NPT.
And then adapt 3/4" NPT to 3/4" hose thread.
And then possibly another adapter to hose thread in Argentina.

There is no immediate link announcing which vendor sells BSP to NPT adapter fittings, in Argentina.
However, the following link sells adapters, in Australia:
http://www.irrigationwarehouse.com.au/category2_1.htm

You can google the following search parameter in Argentina:
Adapt NPT pipe thread to BSP pipe thread

Issue is compounded with 2nd adapter problem.
Melnor sells water timers that screw onto a hose bib.
3/4" hose thread is different than 3/4" NPT pipe thread because 3/4" pipe thread is tapered, while hose thread is straight with no taper.
When connecting a water timer to hose bib, the seal is made with rubber washer.

Home centers in US sell 3/4" NPT pipe thread to 3/4" hose thread.
http://quinbyhardware.com/Products/SKU/4294278/3-4MHX3-4MIP-BRASS-CONNECT/LAWN-and-GARDEN/WATERING/GILMOUR-MFG

You can google the following parameter, but sources might not be in Argentina: 3/4" hose thread to 3/4" pipe thread

Cannot find power adapter for mms171w philips system. Needs AC/AC adapter with 10v ac at 1.8 amps output. Cannot find aftermarket counterpart either. Help. Lost adapter while moving.


Hi there,
What does the other end of the adapter look like?
Is it a conventional circular one or is it a special port like it's thin square like or USB like maybe?
If it's conventional any 10v 1.8amp or 2 amp output should do and a lot of them are available in e-bay or if there's a Best Buy, Staples, Etc near you can just drop a visit purchase one and it should work like a charm.
However if it's not a conventional adapter you may have to contact philips and purchase one that is compatible from them.
Hope this shed some light on your problem!

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 - American Standard Pipe Thread Taper 1) Pipe Size

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.

Cold water pressure poor in shower. Just had Rheem installed.


You might have clog in water lines.
If shower is only place where low pressure exists, then clog is probably at shower valve.
Disassemble valve and see if clog will flush out.
From there, you have to keep moving back along cold water line looking for pipe filled with sediment or elbow that has obstruction.

If pressure problem is bad at every cold tap, but doesn't affect Hot water, then clog is inside Cold line somewhere after water heater connects to cold line.
Buy a pressure gauge that connects to water hose.
Buy adapter that also fits pipe thread.
For example Brady BTG 100.
Test outdoor spigot for baseline pressure.
Open cold tap inside house and see how much pressure drops.
Close cold line and open hot tap and see how much pressure drops.

Next, move pressure gauge along cold water line.
Take apart pipes and inspect for obstruction at elbow or pipes filled with sediment.
Look for any place galvanized pipe connects to copper pipe, since this will be likely place for obstruction because of bi-metal corrosion.

I have a G6A88E water heater in my rv it runs great except behind the front on the bottom on the right as you are looking at it there is a 1 1\2 about pipe that is leaking is there any way to fix this


From description it Sounds like your bottom hook-up for water line coming in.(cold inlet) Depending on what type of connection you have on water line, it may just need tightening, if not it may require a new fitting installed, or the actual 1/2" NPT nipple going in to tanks is faulty. They use plastic, or galvanized pipe nipples usually, but in some cases you may find a check valve there. Either way, you'll have to determine exactly where it's leaking first. Depending on age of tank, it may even be the piece of aluminum welded to tank where 1/2" pipe nipple is installed. I've has 2 this year that rotted right through that and caused a leak, and had to replace the tanks. Let's hope yours just needs tightening, or a fitting replaced. Make sure you use good pipe dope when changing that nipple if necessary. Many use Teflon tape as well on threads, but I've had better luck with pipe dope.

House water pressure is 90psi static, when a faucet is turned on pressure drops to 35psi and water output is considerably less. Why and how do I fix it?


To cause the pressure and flow drop you are experiencing indicates a major restriction in the the main supply pipe to the house. The stop **** where the house supply is connected to the street main would the place to start. Find the faucet that is closest to this and check the pressure/ flow and if that is OK continue to each sucessive faucet in the line. You should be able to narrow down where the restriction could be. Yuo may need the help of a plumber to fix the problem.
If the piping is the very old style galvanised steel pipes. then the rust/corrosion buildup inside the pipes would cause the restriction and is indicated by rusty water coming out if the water has not been used for a few hours. Total replacement is the only fix for this problem.
