"Depending on how heavily use your drains

External drains a routine maintenance, clean by using a high-pressure jetting unit is good practice

Internal drains a routine check to see how the internal drain are flowing and then engineer may use a spring unit to clean the internal drains"

"The best way to clean your drains and keep them Lear a nd free flowing is with a high pressure water jetting system that we have mounted within our vans, any solution/cleaner you put down the drain is literally chucking money away, the liquid will only clean the bottom 3% of the drain call us for a free quote jetdrainskent.
