Low water pressure to entire house
My house was built in 86, I have lived here since 2001 and have had awesome water pressure throughout the house until now. On Saturday I noticed that water pressure was not as strong as it usually is. By end of day today, I cannot run my dishwasher or washer machine and very little water comes out of every single faucet. I also cannot flush any of the toilets in my house. I do not think it has anything to do with my boiler. I have a bell shaped object attached to some piping which I assume is my pressure regulator. I have no idea what to do regarding this as I have a household of six and definitely need some good water pressure. Any suggestions would be helpful. Please let me know if you need more info from me.
Thanks
