Rangemaster Aquaclassic 2 TAC2CM FAQ
- Is this a Genuine Rangemaster Tap part ? Yes it is . If you fit a compatible valve i.e not from your Tap manufacturer the replacement valve can end up slipping on your handle and damage the handle. You might need a new handle and another new valve.
- How do I know which Valve to order ? You need to determine where the drip is coming from e.g the cold water feed or the hot water feed. If in doubt, order a pair. There are more detailed tips / advice here.
- My Valve has a different coloured seal than the one you have sent me : Due to valve modifications over the years we supply the Tap Valve that covers all these changes.
- My tap is leaking at the base of the spout, not the top, what do I need? If your Tap is dripping where the Spout meets the Base then you need to replace your O Ring Kit.
- How do I access the Valve? You need a 2mm allen key to loosen the grub screw underneath the handle. See below for our DIY Guides.
