The installation of most bidets is fairly simple, however, if you are not mechanically inclined, then hire a professional licensed plumber or a trusted handyman to install it for you. But, if you insist on doing it yourself, the following are some ground rules for installing (diagram). bizi bee enterprises assumes no liability for the installation of the product by unlicensed individuals or the following instructions:
1. INFORMATION FOR HYJET ONLY: If you have a Hyjet Bidet please make sure that the nozzle housing connector has 3 O-rings in place. One large O-ring is placed on top, then insert the nozzle housing connector through the top of the Hyjet bidet body (this seals the top of the connector), then one large O-ring at the bottom and one small o-ring on the inside of the connector. After the nozzle housing connector is in place you then attach the nozzle to the connector. Most of the time the nozzle housing is already connected to the bidet body with the top large O-ring already in place. In this case, you will only have one large O-ring and one small o-ring.
2. Make sure that you have all the tools and parts for the job. Typically you will need the following: Rags, small bowl, flashlight, 2 small pipe wrenches, 1 crescent wrench, flat or phillips screwdriver, plumbers tape, replacement washers, hoses and valve (if replacement required).
3. Do not force anything, especially when screwing in and tightening the valves in place, otherwise you may strip the threads. If it is not going in straight or not connecting, then stop and try it another way, until the item can be turned without much effort.
4. It is recommended that you replace old washers when disconnecting old hoses or replace hose. If the toilet is leaking from the tank, then you might need to replace the toilet fill valve or replace the washer. And be careful to only hand tighten any connection to the toilet tank, otherwise you may crack the toilet tank porcelain and that would require replacing the entire tank.
5. If the shut-off valve coming out of the wall, is a one piece valve, with valve and metal flex hose together, then replace the valve with a valve that has threads for attaching a nonmetallic flexible hose. The hose should have washers in both ends. Why? Because by moving the metal hose around, the hose may crack and then it will leak.
6. When moving bidet valves and toilet hoses around, be careful that the washers do not fall out or get misplaced. Losing a washer will cause a major leak in the system. All packages were inspected prior to shipment and all washers, hoses and bidet valves are included.
7. Put plumbers tape on all threads before screwing onto connections, except for metal ball joint connections (electronic models only).
8. Make sure that you have the right bathroom wall valve in place for the bidet you are installing. That would be the valve coming out of the wall. For the HB models that valve should have a threaded 3/8" outlet. The Hyjet and the Electronic models are attached to the toilet tank. The Seojin CB model requires a threaded 1/2" outlet (their diagram is wrong).
9.If the hose sold with the unit does not hook up to the valve, then replace the hose with one that does fit. It is easier and less time consuming to replace a hose, then replacing the valve on the bathroom wall.
10. If you have to buy a valve, make sure that you buy the right outlet size and that the new valve will attach to the pipe coming out of the wall. The pipe coming out of the wall could be copper with an attached sleeve, or 1/2" threaded pipe. It is rarely 3/4" pipe. Whatever size it is, get the right valve for the pipe. Also make sure that you have the right hose that will be attached to the valve and then to the toilet tank.
11. You may need to buy a new flexible toilet hookup. HB models come with the correct hookup to be used with the plastic bidet valve. The Seojin CB bidet do not come with the hoses and will require 1/2" hose attached to plastic bidet valve then to the toilet tank.
12. Check the diagram in the box before installing anything.
13. Have a small bowl or bucket and rags to clean up any water spillage. Also have a flashlight handy, so that you can check for those leaks in an unlighted place. A great flashlight to have is a hands free head flashlight with a band that goes around your head. A small mirror may be helpful for the extra tight places.
14. Before disconnecting the valves, shut off the main water line, going into the house.
15. HB models only: Do the job in stages and test at each stage to make sure there is no water leaks. Replace the wall valve first (if required) then test for leaks by turning on the main water line. Make sure the wall valve is closed before turning on the main. If ok, then shut off the main water line and the wall valve. Install the plastic bidet valve on top of the main valve with plumbers tape and the washer. Make sure that the bidet valve is closed. Turn on the main water line, then turn on the wall valve (keep a bowl nearby). Check for leaks. Turn the plastic bidet valve on and off (water will come out, keep the bowl underneath). The final stage is attaching the tube onto the plastic valve nipple and be careful not to break the nipple.. Also attach the toilet hookup to the tank (make sure washer is in place and you hand tighten, otherwise you might break the porcelain tank). Then test for leaks again.
16. For any model installation please do the job in stages and test, test, test. Then leave everything on and check for leaks again (with a flashlight, if light is low). Check it again in 15 minutes. And then check it again before sleeping and once in the morning. Laying tissue undeneath connections will reveal any tiny droplets falling from a leaking connection. Also feel around each connection and make sure there is no water coming out.
17. Testing in stages is best, because you do not have to uninstall everything to correct problem leaks.
18. IF YOU SHUT-OFF water main. After you have completed the installation and you are sure there are no leaks, make sure that you inform your customer that brown water may come out after shutting the system off or flush the entire system yourself, by turning on and off each water source in the house, including the washer and ice maker. Otherwise, your customer may get brown ice and clothes with brown stains. At least warn them. This is a typical problem when shutting down the water main. Sometimes the only brown water is at the area you are working on.
19. If you are installing a manual bidet, then you might as well buy a new toilet seat and install the new seat on top of the bidet.
20. Also, if you are going to the hardware store take the part with you, so you can try things on for size, but do not take everything else (washers, boxes, bidet..etc), because you might lose them in the hardware store, especially small washers.
21. Finally and most important, keep an eye on the installation connections for the first few hours and days. If you notice any leaks, shut off the valve at the wall and call your installer immediately. If the valve at the wall does not stop the leak, then the valve or pipe is leaking and you should shut off the water at the main water shut off valve. Usually, the main water shut off valve is located outside. Identify these valves before your installer leaves.
