Will this work with a Triton TR 100 and if so what additional parts would be needed to replace the top gauge? Thanks

Hi Steve,I am not 100% sure what is broken on your filter.  But here is a link to the correct Parts breakdown for your Triton TR100. You should be able to find what you need by clicking on those filter part links.

Do you have a video of instructions to change this item?

A  Answered on 5/7/2020 by InyoPools Product Specialist Alex V.

Brian, Unfortunately, we do not have a video. There is a nut that holds the assembly in place. It is located underneath the black filter lid. The filter lid must be removed using a special wrench (Pentair 154527). Once the lid is removed, you will have access to the nut that holds the air relief assembly in place.

Will the above air relief assy clear body fit a Pentair Triton II High Rate Sand Filter TR 100

A  Answered on 4/7/2020 by InyoPools Product Specialist Hector F.

Unfortunately, this will not work for the TR100 filter model. Please click here to view the parts list for that filter. Key number 1 looks to be the air relief assembly.

how can I take the bleeder valve out if the thread is bold and I can't get it out the tank?

A  Answered on 10/9/2019 by Industry Professional

Sorry but there is no way for us to answer your question. It will be a counter clockwise removal, if it was cross threaded on the installation then the damage is most likely already done & you may find you have an issue with the threads on the tank.

Will this fit the TR-100 Pentair Triton II model


A  Answered on 5/3/2019 by InyoPools Product Specialist Lennox H.

Hi, Jay. This assembly will not work with your model filter, you will need the Air Relief Assembly Kit - 154687.

What is a normal amount of time this part will last? I have had to replace mine several times.

A  Answered on 7/30/2017 by InyoPools Product Specialist Lennox H.

Hi, Mr. J. Baxter. This part does not have a life span. How long this part will last will be based on the operating condition.
