# Lake Arbor Plumbing: Split Levels and Below Grade Rooms A split level puts bedrooms, laundry and sometimes a bathroom below grade. That changes how water gets out of the house, and what happens when it cannot. - Sump pump installation and replacement - Floor drain and backup prevention work - Family owned Arvada plumbing, available 24 hours ## What is different about plumbing a split level house? Lake Arbor is a later Arvada subdivision built largely of ranches and split levels. A split level places finished rooms part way below grade, which puts fixtures and floor drains close to or below the level of the building drain. That removes the margin gravity normally gives you, so any restriction downstream shows up as water on a finished floor rather than as a slow sink. Afford-A-Rooter Plumbing works on both the pumps and the drains that protect those rooms. ## Key takeaways - In a split level the lowest fixture is the relief point, so a partial blockage downstream discharges through the basement floor drain first. - A sump pump that has never been tested is not a working sump pump, and the failure is only discovered during the event it was installed for. - Laundry moved to a lower level puts a high volume discharge into a branch that may not have been sized for it. - Afford-A-Rooter Plumbing is family owned, based minutes away in Westminster, and answers Arvada calls 24 hours a day. ## Why does the basement floor drain back up first? Because it is the lowest opening in the system. When something downstream restricts flow, the water in the drain has to go somewhere, and it takes the path of least resistance, which is the lowest fixture in the house. In a split level that is a finished lower level rather than an unfinished cellar, so the damage is immediate and expensive. The right response is to find the restriction rather than to keep mopping. [Rooter service](https://www.affordarooterplumbing.com/rooter/denver-co) handles the heavier blockages and [drain locating and troubleshooting](https://www.affordarooterplumbing.com/drain-cleaning/drain-locating-trouble-shooting/denver-co) narrows down where the restriction actually sits. ## Does a Lake Arbor house need a sump pump? Some do and some do not, depending on how the house sits and whether a pit was built in. Where a pit exists, the pump in it is a mechanical device with a finite life, and the standard failure is a float that has stopped moving freely rather than a burnt out motor. Testing it takes a bucket of water and two minutes. [Sump pump installation](https://www.affordarooterplumbing.com/sump-pump-installation) covers replacement and new installs, and [sump pump not turning on](https://www.affordarooterplumbing.com/sump-pump-not-turning-on) covers the diagnosis when the pit is filling and nothing is happening. ## What does lower level laundry change? A washing machine discharges a large volume in a short burst, and on a lower level that discharge has the least available fall of anywhere in the house. If the standpipe or the branch serving it is undersized or partially restricted, the machine will overflow the standpipe every time it drains, and it will do it on a finished floor. [Residential drain cleaning](https://www.affordarooterplumbing.com/drain-cleaning/residential-drain-cleaning/denver-co) clears the branch, and where the branch is the wrong size, Afford-A-Rooter Plumbing repipes the standpipe properly rather than clearing it again in six months. ## Lake Arbor plumbing services - [Sump Pump Installation](https://www.affordarooterplumbing.com/sump-pump-installation): Replacement and new installs for pits protecting finished lower levels. - [Rooter Service](https://www.affordarooterplumbing.com/rooter/denver-co): For the heavier downstream blockage that is pushing water back up the floor drain. - [Drain Locating and Troubleshooting](https://www.affordarooterplumbing.com/drain-cleaning/drain-locating-trouble-shooting/denver-co): Working out where the restriction is before anyone opens a finished ceiling. - [Residential Drain Cleaning](https://www.affordarooterplumbing.com/drain-cleaning/residential-drain-cleaning/denver-co): Clearing the lower level laundry branch that floods on every wash cycle. - [Water Heater Installation](https://www.affordarooterplumbing.com/water-heaters/water-heater-installation-replacement/denver-co): Replacement in a lower level utility space, on a pan with a proper drain. - [Emergency Plumbing](https://www.affordarooterplumbing.com/plumbing/emergency-plumbing-services/denver-co): Water on a finished lower level is an emergency.

The float should rise, the pump should run, and it should stop cleanly once the pit empties. If any part of that does not happen, it needs attention before the next storm. **Water came up through the basement floor drain. What does that mean?** It means something downstream is restricting flow and the lowest opening in the house is relieving the pressure. Clearing the floor drain itself will not fix it. **The washing machine overflows the standpipe every cycle. Is that a clog?** Sometimes, but on a lower level it is often a branch that was never sized for a washing machine discharge. Clearing it helps briefly and the problem returns. **Do you work on split level houses often?** Constantly. Split levels are a large share of the later north metro housing stock and their drainage behaviour is predictable once you know the layout. **How fast can you get to Lake Arbor?** Quickly.
