Drain Cleaning:

Responsible drain usage means you should never suffer a blocked drain. To help, here’s so free tips and advice from E&E in New York City:
Many drain blockages can be avoided if you pour a cup of boiling hot water down your shower, bathroom sink; bath and kitchen sink plugholes at regular intervals. This helps dissolve up and emulsify deposits, which left untreated can eventually form a blockage.
Try to minimize the amount of solid waste which goes down the kitchen sink with the dirty dishwater. Scraps of food should be removed and placed in the dustbin, rather than passing into the drain where they can create a blockage. Fitting a strainer to the sink can help. 
Use washing detergent sparingly when doing your laundry. Stick to the manufacturers guidelines and don’t go over the top. Way too such soap detergent can form solid deposits on the wall of your drain, reducing drainage flow and ultimately causing a blockage.
Stop loose hair from washing down your bathroom sink, bath or shower plughole by fishing it out and disposing of it in the bin instead. Loose hair can easily become clogged inside the drain, again causing a blockage. Similar to in the kitchen, fitting a strainer to the plughole can help.
If you do have a blocked drain, after it’s been unblocked you’re still at high risk of a repeat drain blockage. Most blocked drains aren’t an isolated incident – more likely flow through your drains is restricted by an extended period of solid deposit. The best thing you can do is have your drains cleaned by a E & E clearance New York – high pressure drain cleaning will restore your drains to their original condition, allowing waste water to flow away freely.
