Recently, we did camera inspection of our sewerage line and overall its good but there are some small cracks and some places where tissues can stuck. Small area has shrub roots growing and interested to know if users conduct jet cleaning by themselves or via plumber?
Now the main thing, we have 2 inspection points under house and 2nd one is under blue metal (pics attached). Instead of removing all the garden gear then pull out blue metal, I would like to know if I can raise this inspection point? Perhaps use 100mm pvc and then a plastic cover on top but I am no expert and hoping someone can throw some light on this??
If it is only occasional heavy blockages or tree roots, I would suggest a professional is your best choice. The equipment they use is a lot more powerful than any D.I.Y. products. If you do want to attempt removing blockages yourself, you can purchase a Karcher High Pressure Cleaner Pipe Cleaning Kit. This kit would be suitable for removing light blockages and debris.
I'd suspect that the black rubber O ring will slip over a Holman 100mm x 1m PVC DWV Pipe. The pipe and O ring are then pushed back into the terracotta pipe. Make sure the O ring is pushed in nice and tight, sealing the pipe in place. You'd then cut the pipe to just below the finished ground level. A Holman 100mm PVC DWV Bolted Trap Screw can then be glued to the pipe, and you can backfill the surrounding gravel.
Alternatively, you could leave the terracotta access intact. Cut the bottom off an Everhard EasyDRAIN Polymer Rainwater Pit Case and place it over the current arrangement. You can then backfill gravel around it. An Everhard EasyDRAIN Polymer Grate to Suit Flo-Way Pit is placed on the pit and lifted when you need to access the terracotta fitting.
Please let me know if you have questions.
Thank you for your reply, may I please ask the link for O ring item as site showing different products.
I've double-checked with a team member in-store, and unfortunately, those large O rings are no longer available. If the current one can't be re-used, you could excavate slightly more around the terracotta and attach a Deks 100mm EW To PVC Rubber Joiner Adaptor. If it fits the mouth on the terracotta pipe, I would prefer this attachment method, as it has a mechanical fixing instead of just the push-fit. Could you please measure across the terracotta and tell me the size? We could then work out whether the Deks adaptor will suit.
Hi @MitchellMc ,
I managed to do the attached (see pics). Please advise if it is acceptable or do I need to dig more? The inside rubber is bit loose as you can see the bend in pics
That's a fair bit larger than what I was expecting. My hope was that we could attach a Deks 100mm EW To PVC Rubber Joiner Adaptor over the terracotta to convert it to PVC. Unfortunately, jumping from 190mm down to 100mm is not possible with Deks fittings, at least not without several convoluted step-down pieces. I'm now even more inclined to suggest cutting the bottom off an Everhard EasyDRAIN Polymer Rainwater Pit Case, placing it over the current arrangement and backfilling with gravel around it. The pit won't be connected to the drain, merely there to hold the soil/gravel back around it and give you an easy access point at ground level.
Let me mention @redracer01 to see if he had any ideas.
Perhaps you can try using a finishing collar in reverse then attach the inspection cover over it. You will need to join them with a bit of PVC 100mm pipe that you will need to cut at the height that is suitable for your purposes. You will need to use deks 2 part glue to attach the PVC to the earthenware pipe. Remember that deks is an air activated glue and must be mixed under water. Be sure to wear protective gear.
Use this upside down.
