Hope is a simple question. The merits, or not, of deciding which is best as isolation valves for a pair of taps, gate valves , stopcocks or 90degree ballvalves, if any?
 
Full bore ISO valves (the same type that use lever valve internals)
 
Full bore ball valves with butterfly head or lever if you have the space.
 
Gone for a pair of these by Peglar.

Much more expensive than some alternatives but hopefully will work when needed to.
 
Most people hate gate valves because most people buy and install rubbish gate valves. Any valve you suggested will work but for how long is down to the quality of the valve its self
 
My place is littered with gate valves half of which will not budge, well maintained by previous occupants! I always thought gate valves were the solution to any isolation problem but reading previous comments appears to be not so.

They seize, get stuck and eventually snap

No real plumber likes or trusts gate valves. The modern lever valves or full flow isolating valves are a major advance in plumbing valves for quality and reliability, and at a similar price to cheap gate valves.
On pipes to a sink unit, the slotted screw type full flow iso valves are more than good enough for reliable turn off valves for servicing or replacing taps or removing sinks.
No need to use lever valves if not in regular use, but still very handy
 
Modern 1/4 turn lever valves? its only the wet environment where that plumbers uses are current period, because they think its modern to them. What about the concord with a 1/4 turn gas valve. also the supplier of gas using the same 1/4 turn for all these decades . The regulation (I,m talking WRAS) has everything to explain itself .
Rant Over
 
I know 1/4 turn lever valves have been around a long time, but really only the last 20 years they have become increasingly popular with water plumbing.

How to identify dripping tap.
Our kitchen mixer tap has started dripping. Like so much of the plumbing in our almost new build bungalow, it is lacking! The plumber didn't install any isolating cocks in the H&C feed to the tap so how can I identify which of the valves is passing? Shut the whole H&C water system down?
