Sump pumps on Laguna Niguel's hillside lots
Two designs of sump pump turn up in Laguna Niguel. We service both, and install both. The submersible kind sits under the water it moves. The pedestal kind stands on a post, motor in the dry. On every call the plumber walks the route the water takes: float switch, check valve, discharge pipe, the outlet end of that pipe, and the electrical receptacle that powers it all. A running motor is evidence of electricity, not of pumping. We judge the pump by the level in the pit.
Often the pump itself is healthy and something beside it is not. The float is wedged under the discharge pipe. The check valve is stuck open, and each cycle lifts water that then drains straight back into the pit. Or the pipe climbs farther than this pump can lift, a mismatch that shows up on lots where the outlet sits well above the basin. The Moulton Niguel Water District keeps 17 lift stations to get sewage over the ridgelines; a yard pump faces the same hills at a smaller scale. Caught on a dry October afternoon, any of the three is a small job. Caught in a downpour, with the slope shedding water toward the back door, the same fault is an emergency.
A replacement pump is picked from two numbers measured at your pit: the vertical rise to the outlet, in feet, and the run of pipe between the two. On a slope the rise is the hard part, since the outlet may be up at yard level or beyond a retaining wall. Buy the twin of a pump that could not manage that rise and the twin will not manage it either. The discharge is set to release where the water keeps moving away, never onto a slope face and never back toward the foundation. Silt comes out of the pit on the same visit. The written price comes first, and the old pump stays plugged in until you accept it.
Six things the plumber looks at
- A float that travels its full range without snagging on a pipe or the side of the pit
- A check valve that closes when the motor stops, so the discharge pipe stays full
- The discharge outlet: where it lets go, and where the water runs from there
- A GFCI receptacle of its own, and a cord that reaches it without an extension
- The floor of the pit, emptied of silt, gravel and leaves
- A fill test at the end: the pit is flooded on purpose and the pump has to empty it and stop unaided
How a failing sump pump gives itself away
- Nonstop running, or a motor that kicks on and off in bursts
- You hear humming in the pit and the level does not move
- Puddles in the downhill garage, or a wet line on the back wall, the morning after rain
- The pit gives off a stale, swampy odor
- No one in the household has watched the pump being tested
- An entire storm went by and the pump stayed silent
A dry-weather test you can do yourself
A Laguna Niguel sump pump can sit through an entire summer and fall without starting once. Then the first long winter storm arrives and it may cycle all night and into the next afternoon. Learn how yours behaves before that. Put a garden hose in the pit, or pour in buckets, and watch for the moment the float tips the switch. From there the level ought to sink at an even pace until the motor cuts out, and a quiet clunk from the check valve should follow. If the level stalls or the clunk never comes, that is a repair for a sunny week, so call.
Which pits deserve a battery backup
A backup pump on a battery makes sense where a dead main pump puts something you value at risk: living space on the downhill side of the house, a garage set into the grade where the water heater and the storage shelves stand, or the parking level beneath a condo building. Heavy rain and a power outage often show up on the same night, and on that night the main pump is only as good as the outlet it is plugged into. A pit that collects nothing but planter or side yard runoff is a different case. There the better spend is usually on the area drains feeding it.
We say which of those two cases yours is before a backup is ever proposed. A backup you do want is priced separately on the written estimate, and it goes in only after your approval.
The low side of a Laguna Niguel lot
Hills are the reason this city has sump pumps at all. Any lot on a slope has a low side, and the pump goes where that low side meets a building: under a downstairs room or a garage cut in below the street, in a catch basin where the slope comes down to the back wall, or on the parking level under attached homes. One home in five here is single-family attached, and Laguna Niguel has over 120 homeowner associations, so a pump that serves a shared garage or a common slope often brings the association and its CC&Rs into the job.
Water on a hillside lot needs a planned way out. Terrace drains, area drains and the drain lines laid behind a retaining wall all do one thing: they carry water off the slope and out of the ground beside a building. A yard sump finishes that work at the low point of the lot: it gathers the water, then moves it away from the house to a place where it does no harm. If the pump below a slope stops, runoff backs up against the foundation and the soil beside the house stays saturated. Cracks opening in a slope or a retaining wall beginning to lean are a matter for a geotechnical engineer. Our part is the pump and its pipe.
Where the pit sits changes the visit. A pump set in a garage slab is a short walk from the driveway. A yard basin below terraces, down a steep side path or tucked beyond a retaining wall, has to be reached on foot with the equipment in hand. Say which one you have when you phone. A person answers the phone at any hour. Knowing the spot, the plumber heads to your address equipped for it.
