"Tony and Burt arrived when they said they would, even called to let me now they were on their way. They checked the water pressure outside first to see if there was an issue.  The pressure was fine but then I took them to the basement and showed them the pipe.  They explained what the reducer valve does and the reason for the green on the pipes. They replaced the valve immediately and the pipes as well since they said what I saw on the outside, was on the inside as well..yuck! They turned the water back on and then ran the faucets in the house to get all the air out.  All was well until I tried to turn the kitchen faucet on 'high' but the same pressure came out.  It seemed weak and not as strong as before.  I called Tony again and he returned the next day to adjust the pressure, even showed me how!  That is professional service at its best.

Sump Pump Installation FAQs, answered by experts

One common reason a sump pump stops working is improper sizing. Different locations need different sizes and power ratings of sump pumps depending on the typical amount of water the pump needs to manage. If your sump pump is too small for the quantity of water, it can overwork and either burn out or reduce the life of the unit. If the pump is too big, it can overwork and burn out early. 

Start by calling a plumber if you want to install a sump pump battery backup. Talk to them about your situation and needs. Sometimes, electricians or waterproofing contractors will install a battery backup, and in that case, the plumber you call should be able to point you in the right direction.

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.

Yes, it’s possible to install a sewage ejector pump outside rather than in a basement. However, there may be some extra steps involved, including running pipes from the inside to the outside of your home and digging (and re-filling) a hole for the basin. If you aren’t comfortable with this type of work, contact a plumbing pro to handle it for you.

To maintain your sump pump, start by checking it every three to four months to ensure it’s in working order. Clear any debris from the pit because blockages can prevent the pump from operating efficiently. You should also test the pump by pouring a bucket of water into the pit. If it turns on automatically and drains the water, it’s functioning correctly. Inspect the discharge line for clogs, and ensure it directs water away from your home. Once a year, clean the pump itself, and consider having it professionally serviced for optimal performance.
