"This review is really about all Peglar ball valves.
Firstly the negative bit - they are more expensive that other ball valves.
Now the positive bit - You only get what you pay for and these valves will last forever. If you are a DIYer then I suggest you spend the extra cash and get the best for your home. For about £1.50 cheaper you can get a similar valve and im sure they will do the job but I prefer to spend the extra money and get a good quality product.
Now the techical bit - A full bore valve will give you much better flow rates than normal isolator valves. If you are fitting mixer taps and want to isolate the hot and cold water supply, use the full bore valve. You will be amazed by the difference."
