32mm stopcock. £15 OR £60? What is the difference?


Recommended Posts

I just bought a 32mm stopcock for £30 from jdp, consisting of a plain stopcock plus an adaptor. The guy dissuaded me from the £60 ones on display. 

I see them online at £15 ish.

I am assuming there is a great difference in quality. I know some turn smoothly and others stiffly. 

With lots of bits to buy, what should the strategy be on sourcing fittings ?

is it full bore? some valves are smaller than the pipes they fit to and can cause headloss.

 

Also, some are designed for outdoor use, and others indoor only. Also things like integrated non-return (check) valves.

Personally, for the hassle factor I would always go Plasson. You will find that as soon as you get away from bog standard fittings (and 32mm is just starting to get non-standard) that the prices vary wildly - so you need to shop around and ask for discounts and be prepared to order on-line and wait. This isn't B&Q stuff anymore.

That is why I went to JDP. I have always found the service and advice good. 

 I don't need much advice on drains, but water mains is not my skill.  This will be for the plant room end of the new water main. 

 

 I also went there for a chat about the rest of the project.   ie what brands they stock and discount.

 

 I had a long chat about why their online price was much the same as the shop price is after 10% discount. It seems there isn't a full price unless you are an amateur who doesn't ask for a discount.

 In  that time, about 5 'men with vans' came in and collected various very large drainage  parts. I think this may be the main business for JDP ie having good stocks of stuff that is needed urgently. Of course these stocks and the depot create a cost.

They were also good enough to agree that I will get best prices shopping around (or Screwfix) , but for a big order ask for a quote.

 

btw their underground drains are from Dyka, a Netherlands company.

 

Plasson was the make they talked me out of!

I used Plasson throughout our 32mm supply, sourced via JDP as well. That Plasson stoptap in your picture has been in my plant room under 10-12bar pressure for over 2 yrs and no issues.
