How to remove stuck Holman stormwater cap?

[Tony11]

Hi there

I have a rainwater tank connected to the house roof (new build) and whoever installed the Holman Stormwater Caps on the intake pipes put them on so tight I cannot get them off. We’re expecting our first rains in ages on the weekend and I’m after any tips on how to get them off when they are this over tightened. 

Tried by hand first then bought one of those strap levers to try and get some leverage. One of them shifted with that but the other one is completely stuck. So is there a knack for getting them loose without breaking them?

Hi Tony, 

im the same down pipes connected to tank and need access the PVC caps so i can clean the pipes each year. i found this tool in picture. opens up and clamps onto the plastic cap.the racket makes the jaws bite in allowing you to undo and remove the Cap

Hello @jimtom1 

Welcome to the Bunnings Workshop community. It's wonderful to have you join us.

Thanks for sharing your knowledge and experience with the community. Let me tag @Tony11 to make them aware of your recommendation. If I'm not mistaken that is a self-adjusting oil filter removal tool. But I suspect it will work just as well in removing PVC endcaps.

Were keen to hear more about all your projects and plans around the house and garden. Please feel free to reach out whenever you need assistance or would like to share project with the community.

Hi Eric,

I bought the same Holman 90mm Threaded PVC Storm Cap for something DIY which I would need to remove and empty the water. But the problem is the o-ring is not helping with tightening and water is still leaking. I am wondering if that's why Tony experienced the issue because the plumber had to use extra silicone to seal it. What is your suggestion? How can I seal it in a way I can remove it later?

Hi @mbanafshi,

Do you have a photo of the D.I.Y. project you are working on? This would help our members offer their best advice specific to your project.

These caps are supposed to be used as inspection points on the top of stormwater pipes. If they are not on the top, water will apply sideways or downward pressure. While the O-ring should create a seal, they are not designed for a lot of pressure so there may be some leaks if it is being used to retain water.

If the project comes under any pressure, then we may need to rethink the design, which I would be happy to assist with if you can provide some details.

Let me know what you think.
