wort chiller, cooler lauter tun valve

I am currently brewing double batches.

I complete 3 per day. So I am always trying to find simple equipment to reduce time for each step.

I use a 25'-0" 3/8" copper tube with cool water running through it.

I purchased a 50'-0" 1/4" tube. For my next evolution in chilling. Having some fitting problems but I should be able to solve this shortly at the hardware store.

I here there are other approaches. Basically I am trying to reduce cooling time. Ie a pump with a recirculating water or something like that? Any suggestions.

Here is another one. Where do I buy a valve that I can insert into my cooler/lauter tun. to connect to my copper manifold. I have been electric taping a tube to my cooler drain line which is also connected to my manifold. It takes time to set up & leaks. I am hoping to have a system so the cooler can also maintain its use as a cooler but if that is not possible I will buy another cooler.

Thanks for the help in advance
