Good deal! Now you have enough information to solve the problem.
There are two basic ways. You could use 2 On-Delay (TON) timers (each set for 5 seconds - this is a more simple method),
or you could use only 1 On-Delay (TON) timer set for 10 seconds. With one timer, you could use comparison instructions to control when each pump started by comparing the timer accumulator (T4:0.ACC) word to "5" then to "10". This would be a more advanced method.
