I have an isolation valve which I can use if I go away. However if there is an easy way to fix the problem without taking the whole thing apart I would love to know! I'm hoping it is something relatively easy for me as a novice.
Thanks in advance!

I will try to Help You on the basis that You cannot just change the Torbeck Valve.
BUT it might be that after trying what I suggest You will have to gain Access to be able to replace the entire Valve - because the Parts that I am going to suggest that You try to use from a NEW Torbeck Valve may NOT be Compatible with the Existing Valve due to the Redesign by Torbeck / Opella [?].
Usually these Plastic Float Valves would just be Replaced - they are just NOT worth trying to Adjust / Mess about with - especially where High Water Pressure exists to the Inlet.
Sometimes a small piece of Grit gets onto the Valve Diaphragm and causes it to not completely shut off - the grit can Indent the Diaphragm meaning that even if it was removed the Diaphragm would still not Close Off the Water Flow completely.
I would suggest that You TRY obtaining a New Torbeck Valve from a Plumbers Merchant and Use the New Parts to replace the `Working Parts` of the existing Valve - obviously using the Isolating Valve.
If possible you might want to take the `Working Parts` from the existing Valve to the Plumbers Merchant in order to compare them with the New Valve - IF You can actually see it through the Packaging / take it out of the Box.
BUT - there has been a redesign of the Torbeck Valve since yours was fitted which might make using the New Parts Impossible - the `New` Design enables the Valve to be disconnected from the Upstand within the W.C. Cistern. -
You should Note the assembly of the [existing] Torbeck Valve regarding refitting the existing Parts.
The Torbeck Valve may well be packaged in either a Box or a Poly Bag - so You would have to purchase it if what You can see looks like it will fit your existing Valve Body / Upstand - even then finding out that the `Working Parts` are NOT compatible with the existing Valve [?].
When You disassemble the existing Torbeck Valve you must ensure that everything is completely clean prior to reassembly with the New Parts - and ENSURE that You fit the New Parts as they come out of thew New Valve.
As the existing valve is Plastic be careful not to break the Upstand.
There is a Flow restrictor supplied with these Float Valves - it looks like a Plastic `Archimedes Screw` BUT this has to be fitted into the Inlet of the Valve Upstand so hopefully the existing one is O.K.
I CANNOT STATE THAT THE PARTS ARE INTERCHANGEABLE - THERE MAY WELL BE A DIFFERENCE IN THE NEW DESIGN `WORKING PARTS` / FILTER ETC.
Sorry that I cannot be more positive Tom - My Company does not use these Float Valves unless they are supplied with specified W.C. Cisterns - which is NOT often.
Here is a Link to some details about the New Design Torbeck Valve - Bottom Inlet:
