## Description

Fluidmaster PRO550UK Top/Side/Front Mounted Dual Flush Valve - White : desertcart.co.uk: DIY & Tools

Review: Easy to fit and a great price - Absolutely brilliant. Toilet started running constantly after every flush. Bought this as it was a direct replacement for the one I’d had installed for the last 5 years or so. Turn off water, flush the toilet. Unscrew the flush from inside the toilet and fit in reverse the new flush. Tighten screw for inlet pipe and job done. Now flushes perfectly and no more running after a flush. Probably took about 30 mins but that’s because I had to fiddle about undoing a stuck inlet nut and washer.

## Questions & Answers

**Q: how did i adjust the overflow pipe ? mine is overflowing and i carnt fit a flush master valve [no room}**
A: The overflow is part of the installed system. You don't need your normal overflow pipe - you can throw it away. The overflow works through the plumbing you have just fitted. Try unscrewing the over flow tube supplied - I found that it was too high and had the problem you describe - then adjust the float ball (if necessary) to make sure the level of the water does not reach the height of the opening in the in-built system.

**Q: Anybody know how this unit compares to the Torbeck Variflush?**
A: Both units are from very good manufactures we sell more of the Torbeck Variflush but that doesn't mean its a better product.Kind regards,Jo.

**Q: how to change batteries**
A: There are no batteries it works by siphon alone.

**Q: Is this a complete system? I can't see a ballcock in the image.**
A: No it's not a complete system.  IT is only the flush mechanism.  You don't need to change the float if it's OK.  I fyou have a close-coupled toilet, this requires you to remove the cistern and I recommend you take the opportunity to replace the close coupling kit.

### ⭐⭐⭐⭐ Having never done a job like this before I thought a review of the product ...
*by C***L on 5 November 2016*

Amazon yet again have delivered, I received these on the same day as I ordered, delivery was by prime and as always very efficient. To the product: - Reason for purchase – When attempting to fix our toilet system after the flush had broken, the float also broke. So basically a new system was needed. Having never done a job like this before I thought a review of the product and how hard it was to do it was in order. The products comes in a retail box. It comes in a hassle free packaging so there's no need for scissors. It contains: - 1 x Dual flush system 1 x Dual button 1 x Large Spacer for button 1 x Rubber Gasket The product feels great, it a mini version of what I've seen before which is ideal as it needed to fit in the downstairs toilet where its a mini toilet. It fits in perfectly. Installation was much easier than I expected. Step 1 - Turn off the water to the toilet Step 2 - Empty the toilet system Step 3 - Undo the screws holding the toilet system to the toilet so you can get to the bottom of the system Step 4 - Unscrew the nut at the base of the toilet system that holds the flush to the toilet. Step 5 - Remove the old flush Step 6 - Repeat the above steps in the reverse order to assemble. Step 12 - Add the button to the toilet lid, using the space if required Step 13 - Click the cable into the button The device gives you the choice of how much is a short flush and how much is a large flush. I went for a 25% for short flush as thats enough for a number 1 It was maybe the simplest bit of DIY that looked daughting but it was easy. Even if you went wrong, you just turn off the water. All in all, a great product. *If you have any questions, then click my profile and drop me a message and I will be happy to help you. To understand my star rating please see my profile. *
