[bandejapaisa]

Why would you choose one over the other?

Similar price... surely the one with the knob on it is faster and easier to use?

Yes but more bulky and intrusive, depends on where it is to be fitted.

Both are horrid and prone to leaking.

One needs a tool to make the leaks doubly impressive.

Use proper valves.

Can you give me an example of a proper valve please?

 

[Steelmasons]

A full way lever valve
A full way gate valve
A full way ballofix valve
A stop cock

All being brass/chrome with none of that plastic ****e.

I love plastic. You plumbers are far too passionate about your metals...

Seeing this plastic carp day in and day out wherby the control handles either snap off or sieze then I'm certain you would change your mind , the valve with the slot for a screwdriver wouldnt last five miutes without shearing/striping the plastic.

You get what you pay for.

I'll take your word for it.

However, I've just bought a place with copper pipes and metal fittings everywhere, and they're all seized or the isolation valves won't seal properly, or the stop cocks won't budge....!!

You buy a car and it has never been serviced... when it breaks do you balme the car or the owner that didn't maintain it perolery?


All service valves and stop cocks should be checked and tested (i.e., used) once or twice a year otherwise they will seize. that plastic shyte will seize or leak regardless and will be a bigger ball ache to remove once those collets and grab rings have had time to bed in.

But then what do we know?

You DIY'ers have far more knowledge and experience that we do. Why not bung a 2MW combi boiler in your gaff for good measure. Alex Crap will be along soon to tell you that's a good idea as it will modulate down to 500MW and then his 1" manifold (sorry header) will take care of the short cycling.


FFS - why do people come on here for free professional advice and then argue the toss?

Mind you consultants are even worse - just noticed on some drawings that the 20kW AU for the pool has 35mm flow and returns

Twarts!

Who's arguing? I just stated a fact about my current metal fittings.

I'm taking the advice on board, I'm not disregarding it - I'm going to use the metal service valves - i'd like push fit ones if you can get that.

 

[Dan Robinson]

You can get them but I wouldn't advise it Fir the reasons I stated above.
