Expansion tank:  Do I need one?   

We get this question quite often and the answer is yes.  First of all, it's per code in Howard County and the surrounding counties.  Second, it's for the protection of your plumbing system in the long run.  When you have a closed plumbing system (one-way valve) which is what most homes in the area have.  This expansion tank will act as an overflow collecting any extra volume of water from flowing into your water heater; protecting it from damage.  In turn, this is also to protect that excess pressure from any damage that could occur in your piping or appliances.  Things like your faucets dripping, banging pipes, running toilets, and short life on your appliances can all be caused by thermal expansion.

Garbage Disposal Tips:   

With a lot, more people home cooking we want to give you a few reminders this year! The garbage disposal is meant for food waste only and it should be pushed through slowly and gradually so your blades do not get overloaded and stuck.  Egg shells, Large potato pieces, and any kinds of seeds/nuts can get stuck in your disposal.  Foods like Bread, Pasta, and Rice will expand in water and should NOT be put in your disposal.
