Plumbers in Connecticut have been reported saying that their businesses have had to suffer under the impact of Covid-19 pandemic. Earlier, customers did not hesitate to be in close proximity with plumbers when the latter came to commercial or residential buildings. Under the current situation and the protocols of social distancing, there has been a slight drop in the demand for plumbing services. However, plumbing falls under the category of “essential services” and in comparison to other industries, the plumbing industry continues to thrive at a stable rate. In case of emergencies at homes or offices, plumbing services cannot be avoided.  The demand for plumbers has been relatively better off.  As the situation improves, it can be expected that more plumbing jobs will be created and the scope will continue to grow at a healthy rate.
