Cheap Valves?

[Rorie]

I am looking to have a flow of water circulating down past all my tanks with a T junction above each one with a valve/tap so i can select which tanks will have fresh water put into them...but the cheapest i can find is 22mm £9 ish. The pipe is 32mm i think so i will have to use a reducer which is fine, but still £9 per tank is not cheap!

Any suggestions?

Cheers

what sort of pipe are you using?

Look at ball valves. They are usually a third the price of a similar sized gate valve.

if you're going to reduce the pipe size, you could use an isolating valve, the type you open and close with a screw driver, they are only pence.

I have 32mm solvent weld plastic waste pipe. I figured it would be worth reducing after the T just so that the cost of the valve is cheaper ....smaller = cheaper was my logic.

Got any links to the suggestions?

Cheers

thats much better pricing haha.

Any idea how i would connect that into my waste pipe system?

Do you have to use waste pipe or can you get schedule 40 pvc? PVC would be easier to work with, then you could just use reducers and adaptors to add those.

I have my 32mm PVC waste pipe already which is why i was planning on using that, but all the couplings, T joints, reducers and everything else will cost a fair bit, so i have decided to use the hose pipe and joints that go along with the valve you showed me. I think the total cost for everything will be £50, rather than £90 just for the ball valves if i stuck with the waste pipe.

Thanks for the help

No problem.

My problem continues.

After getting a quote of £150 for all the bits i'd need to build my system using the irrigation system, i am looking at another option. Back to my 32mm solvent weld pipe.

My thinking is. take a TEE off the 32mm pipe,

add a reducer (solvent weld overflow) to the tee bringing it down to 22mm

Then from there i need to add a push fit reducer from 22mm to 15mm

Then connect a 15mm isolating valve

This appears to be the cheapest option as the 15mm valve is only a couple pounds. BUT, can i connect the 22-15 reducer to solvent weld? Is the push-fit pieces i am looking at designed for copper rather than plastic? Reducing it to 15 means i can add a cheap valve. The 22mm valve is about £8!

Help please

15mm push fit accepts either copper or plastic pipe; If using plastic you need to put an insert into the pipe so it does not compress. The one you show comes with metal inserts and the white push fit uses plastic inserts. You should also be able to solvent weld into the reducer IF it is a tight fit..

 

[Rorie]

i guess that is the main question - whether its gonna fit or not. I know compression fit pipe and weld pipe are different sizes...
