Help! I forgot to clean out the lines in my jockey box last year.

I have the connections to chain my four coils together but my March and Riptide pumps aren't strong enough to even do two at time, too much resistance. I will give my Spike Flow a shot but I doubt it will either. So I have been wondering what size pump might do at at least two coils (I have 2 fifty 2 seventy foot coils).

Connect them in parallel, cleaning them all at once. As long as liquid moves through the lines it's cleaning, high speed is not needed. Now warm or hot cleans better than cold, many chemical reactions typically double in speed at every 10°C temp increase.

I've had a short pumps course and could be wrong here but I don't think it matters whether the lines are parallel or in series. I think one would add up the total resistence of both lines after the pump. Two or more pumps however it does make a difference whether the pumps are in series or parallel but I need to refresh my memory on that as to how it works as it just occurred to me that could be a solution.

Each line/coil has resistance. In series, all those resistances are added, reducing the flow.
In parallel, the pump's max head pressure, and thus flow rate, limits the total flow through all coils combined.

Gotcha thanks! I COMPLETELY forgot the section on laterals and anything more advanced. I did find my course notes. Thinking back, I did previously see at least one mention of using a manifold for something like this in the forum but it didn't strike a chord. Now if I am reading my notes correctly, I could put my two pumps in series to try to clean two coils at once, since I couldn't even pump through two coils before. However, sounds like a manifold (2 or 4 way) would be the better option and I could increase the flow rate by putting the pumps in parallel. Looks like I have all the fittings I need except a couple of ptc tees. It was drudgery doing these one at a time!

@Stoney28 I have Intertap faucets on my jockey box. These have threaded spouts, and there is a growler attachment that threads into the faucet with a barb. On my brew rig, I will then run the line back to my BK where I can keep PBW warm and feed it to my pumps. From the pump to a barbed x ball lock QD will get the cleaning solution to the coils. Since I have Evabarrier tubing, I can build a manifold out of three ptc tees and a ball lock disconnect, since I am trying to do them all at once.
