**Q: what is the valve on the end? is that a schraeder valve that I can use to connect air? does it have the "valve" part or is it just open threads?**
A: yes, same as a car tire valve

**Q: How do you inflate this**
A: You can pump air in it with an air pump, this test plug comes with an air valve on one end, or you can inflate with water as well. 
The handle serves as a tool to remove the air valve if you choose to use water to inflate.

**Q: What is the difference between this and the tp34? there is a slight price difference and the 34 is a waffled body. anything else that is significant?**
A: hello,

the TP34SB has a smooth body and is easier to use if you need the test plug to be a little more flexible in the pipe. 

the TP34 is just the waffle body which means its more stiff and obviously has more rubber. 

i hope this helps and if you need any more information please do not hesitate to reach out. 

thanks
