How many pounds of pressure can Jet Swets handle?

    Every Jet Swet is calibrated to hold a maximum of 65 psi. We have heard of plumbers using them on much higher-pressure situations, but at that moment they forfeit our warranty, and we forfeit any liability.

How far into the pipe should the Jet Swet gasket be inserted?

    The only part of the tool susceptible to heat damage is the gasket at the end of the tool. It is made of a special silicon/EPDM composite that withstands extreme heat, but you cannot solder right over it. We recommend placing the tool at least 5 inches into the pipe, away from the soldering site. If the job does not permit for this rule, you can place a wet rag around the pipe at the point where the gasket resides to keep it cool. If the gasket is unavoidably damaged, we make replacement gaskets very cheap and easy to replace.

How do I change the gaskets?

    Jet Swets washers look the same from the outside as any other washer you have ever seen, but on the inside, they are quite different. It is therefore important, when replacing parts or servicing the tool that you keep track of the washers and the order in which they were removed from the tool. The tool can be disassembled using a normal wrench. Make sure you replace the gasket with a correct sized gasket. Each tool is calibrated to use a specific gasket with specific properties. By using incorrect gaskets on your tool, you not only void the warranty, but you run the risk of damaging the tool, the pipe system or the tool not working.

What kind of maintenance should I do on the tools?

    The only maintenance on the tools is to replace the gaskets if they ever get torn, burned or misshapen. Secondly, you should re-grease the threads under the middle “tension” nut. This can be done by simply disassembling the tool from the gasket end. We recommend using a non-water soluble grease such as the “Boat & Marine Grease” sold at your favorite auto-supply shop such as Pep-Boys.

My gaskets are being chewed up, what’s the problem?

    Most of the time, if the gasket comes out of the pipe misshapen or chewed up, there are two reasons:
    1. The plumber before you did not ream the pipe correctly, leaving burrs inside which very often chew up the gasket.
    2. The plumber over-tightened the gasket in such a way as to push the washers through the gasket and were torn out.

But I Just Use Bread!
Use Jet Swet Products - Never Use Bread!

      You won’t believe how often we hear this. We’ve all used our sandwich bread or Mrs. Jones’ bread to stop that annoying leak on a job. The problems with bread, and the reasons we invented Jet Swets are:

1: Bread holds almost no pressure at all. There’s nothing more annoying than working on a pipe with bread in it when the bread gives way and the released water ruins your solder seal. Jet Swets hold 65 lbs. of pressure instantly and all day long!
2: You still have to wait for a long time until the water gets down to enough of a trickle where you can use bread. Jet Swets can be used instantly upon getting to the job and turning off the water.
3: When that chunk of bread finally dissolves, it gums up the fixture and valves in the system.
4: It just looks unprofessional…we mean, c’mon… its bread.

What kind of pipe do Jet Swets work with?
The Jet Swet can be used with almost all kinds of seamless pipe (meaning there is not a bead of solder or a fold down the leinght of the pipe).

What if I have more than 65 lbs of pressure in the system?

    Yes, as with any repair job, Jet Swets are to be used while the water pressure is turned off. Jet Swets are designed only to hold back the draining and siphoning water that keeps you from doing your repair. Many times, the draining and siphoning water still build up more than 65 lbs of pressure. In these cases, plumbers have told us the easiest way to get the pressure below 65 lbs is to open a bunch of sink and tub fixtures in the system until it is safe to use the Jet Swet.

Do I need to shut off the water to the system in order to use a Jet Swet?


What is the warranty?

    There is a 1 year warranty on the steel and aluminum components of the Jet Swet. The gasket has no warranty as they can be chewed up in the pipe due to circumstances out of your or my control. See the above comment on chewed up gaskets.

Do the large sizes come in kits?

    No, the 2-1/2″, 3″ and 4″ Jet Swets, whether “normal” style or Flo-Thru are just so big, that they could not go in any case that you would want to carry around. They are sold “Bulk” style, meaning it is just the too by itself.

Do you make custom or longer Jet Swets?

    Yes. They are special order and take a bit of time to make, but Jet Swets can be made as long as 50″. Please call well in advance of these types of jobs so we can make one for you. It takes roughly about 3 weeks.

Can I get them Next Day?

    Yes, we offer all the typical UPS shipping options: Next Day Air early, standard and saver. Second Day Air, Three Day Select, Saturday Delivery, and in the event of an emergency, same day to anywhere in the world delivery service.

What repair parts do you make for the Jet Swet?

    The only repair part we make is for the only part that could ever go bad: the gasket. We make a replacement gasket for every size tool. We also sell a repair kit called the 1751 which is a kit of all the nuts, washers and gaskets to repair one each of the 1/2″, 3/4″ and 1″ Jet Swets for those of us who have a tendency to loose small parts.

The problem that most plumber’s face with draining the system is one of a lack of speed and/or professionalism. Many times, in the case of maintenance personnel, the building’s water cannot be shut down more than a couple of minutes. In the case of plumbers, repeat customers are more likely to be retained by doing a job more quickly and efficiently, instead of charging additional hours to just watch water drain.

What is a Flo-Thru?

Flo-Thru™ Jet Swets™ are even more advanced then the previous single tool models. They are built with a 1/2″ cavity down the center of the tool to allow water or air to drain from the system through a 3/4″ hose outlet while the repair is in progress!

They are made from the same “professional grade” materials as the Jet Swets™ and have a hose connection attached to the end of the hollow handle. This connection allows you to attach a garden hose to the end of the tool which directs the draining water to a floor sink or gutter while you continue the repair.

Flo-Thru™ Jet Swets™ are designed for 1-1/2″, 2.00″, 2-1/2″, 3.00″ and 4.00″ pipe systems and can withhold a maximum of 65 lbs. of head pressure.

A major benefit of the Flo-Thru™ Jet Swet™ line is that not only can water be drained, but when working on swimming pools or like projects, an air supply at a maximum of 65 lbs. can be added through the Flo-Thru™ Jet Swet™ into the plumbing system for pressurized testing.

Flo-Thru™ Jet Swets™ can be used with almost all kinds of seamless pipe such as: Copper pipe, PVC pipe, ABS pipe, Steel pipe, and Black Pipe.

The benefits are that these new Flo-Thru™ Jet Swets™ are cleaner, more controllable, multi functional and effect a quicker repair on any plumbing system.

Jet Swet Repairs take 10-15 Minutes to Complete! - Jet Swet 2-1/2 inch Single Tool

The Jet Swet is used by the plumber upon arrival to instantly be in control of any water situation.

The Jet Swet is used by first turning off the active water pressure at the street, opening the faulty valve (if it won’t open, most plumbers just cut the valve off), inserting the Jet Swet through the draining water stream, through the valve or virgin pipe, compressing the Jet Swet gasket and instantly shutting off the water (up to 65 Lbs.!). Now the plumber can immediately repair the pipe or valve, right over the Jet Swet tool!

Once the Jet Swet is stopping the water, you can solder on a new FULL–PORT or gate valve, right over the Jet Swet . If your repair requires you to solder on a restrictive valve, from which the Jet Swet cannot be removed, instead of soldering on a regulatory valve, you solder a male nipple onto the pipe over the Jet Swet TM, remove the Jet Swet from the pipe and then just thread on any “threaded” regulatory valve you want. Close the valve and you are done!

The Plumber can move on to his next job quickly while still being paid for the first job, thus making more per hour and paying for his Jet Swet tools in only a few jobs.

Jet Swet tools are made of the highest quality materials possible: High tinsel strength steel, Aircraft aluminum, and Gaskets of pure silicon!

The Jet Swet is essential for Building Maintenance Crews, because the management cannot afford to have the water shut off for very long. In many cases, every minute the water is shut off, the management is loosing money or public appeal (like in hospitals, hotels, casinos, convention centers, etc.). The Jet Swet helps repair costly problems in minutes, which normally would take hours.

Most times a maintenance crew must go through their management to get funding for new tools. When it is explained to the management that this tool allows the repair to be done by only shutting off the water for minutes instead of hours, funding is almost always approved.
