Question 1

Do you just unscrew the valve body or do you have to remove the part it screws into? If just the valve body is there a tool recommendation?

Accepted Answer

To remove the valve body, you first must remove the filter lid, using the tool that came with the filter. Using a spray lubricant around the gasket will help remove it. I use an oil base stainless steel cleaner polish. On the under side of the filter lid, there is a black poly nut, which requires a gentle touch with a channel lock or similar. All gaskets and O-rings need to be cleaned with the same lubricant and wiped clean, before placing them back on.

Question 2

Does it include the white O-ring?

Accepted Answer

As far as I know, we have never had the white "O" ring. We replaced the seating "O" ring with a replacement from Lowes, which seems to be working out well. On chlorine feeder applications we use a Viton replacement "O" ring.

Question 3

Do you have to do something to "release" the pressure gauge?  Our assembly is installed and working, but gauge reads "zero".

Accepted Answer

The screw on the back of this manual relief valve should release air and water from the sand filter when the pump is running. To remove the relief valve to install a new assembly there is a wrench. the entire round black assembly is unscrewed and then you can unscrew the valve separately to install the replacement. Never use the wrench to remove the top of the sand filter while it is running or still under pressure. If your system is running and the gauge is still reading zero your gauge is broken. The wrench for the Triton II Sand filter is also available on Amazon it is not possible to install this valve without the wrench.

Question 4

Does this fit the Triton II TR100 (without the c) part number 140210. The Manual Air Relief assembly that is on the filter now is also clear.

Accepted Answer

I have a Triton TR100 140210, without the "C", and this fits perfectly. The 154689 Tee assembly DOES NOT FIT. You can, however, look at your pump and tell which is which. They don't look anything alike, and you can immediately tell just by looking at if you need this unit, or the smaller Tee shaped thing.
