Do both the front and rear end caps of the liquid ring vacuum pump have flushing and drainage ports that require external access? ?

Gentle experts, both the front and rear covers of the liquid ring vacuum pump have a flushing port and a liquid discharge port. I have the following questions: 1. If it is used as a lever, do both of these ports need to be connected externally? 2. If necessary, is it required to use valves to separate these two pipelines before combining them, and will there be any impact between them?
In most cases, it is sufficient to connect one end only, as the interior is interconnected; by connecting one end, it is possible to drain more than 95% of the liquid inside the pump. If the working fluid is corrosive or contaminated, it is necessary to connect both ends, using valves to control each connection. After draining the liquid, it is advisable to rinse the area several times with water and then dry it with compressed air
