TROUBLE SHOOTING     

 
 

1.

 

the cone washer we provided is straight, not spiral).  Use Teflon tape on threaded parts to prevent leaks. Then tighten the 
connection. 

2.

 

For Solid Copper riser:  Same procedure as flex tubing except you must cut a piece of the riser tube about 3/ 4” to 1” so the 
adapter can fit between faucet and riser tube.  Use Teflon tape to prevent leaks.  

3.

 

Install the angle needle valve to adapter if you have not done so in procedure #4. 

4.

 

For connecting red tubing to angle needle valve, refer to the photo below. Then push tubing through the brass nut, then the 
sleeve, then put plastic insert inside the tubing, then push sleeve against the insert, then screw on the brass nut.  Don’t over 
tighten it.  But it has to be tight. 

 

 

1.  feed water adapter ½” connect to 
base of kitchen faucet 

 

1. buy a ½ pipe to ½” pipe hose  
2. ½ to ½” nipple fitting.   
3.  adapter.  
4.  your existing faucet pipe 

 

Many times, it is easier to use the existing 
cone washer than using the new one. 

 

If there is not enough space under the sink 
base, or it’s difficult to get to, you can 
disconnect the riser from the cold-water valve 
side.  If the fitting size does not match, buy 
size-changing fittings, or buy a new flex riser 
with matching sizes. 

 

Many times, it is easier to buy an additional 
stainless steel braded flex riser and a ½” 
nipple to put in between the bottom of the 
faucet male thread and the feed water adapter 
(Don’t buy the spiral type) so you can easily 
put the feed water adapter between two risers.  
This is the EASIEST way.  Spend additional 
$5 on the riser may save you a lot of time. 

 

Feed water adapter with Ball valve 

 

 

1. put Teflon tape on the thread, put only 3 turns 
2. push tubing through the nut,  
3. push tubing all the way into the connection,  
4. screw on the nut tight using a wrench 

STEP 4:  MOUNTING THE DRAIN SADDLE VALVE  (don’t put in shaded area) 

 

 

Position the drain 

saddle in desired location, mark spot.  You need to consider 
available space for drain tubing
