Septic Riser and Lid Installation in Medina, WA

If your septic company has to dig up the lid every time they visit, a riser can pay for itself. Risers extend the tank openings to the surface and are capped with lids that lock.

Request a call and a company working in Medina will explain the options and install risers on your tank.

What risers do for a septic tank

Risers extend the tank openings to ground level. Instead of searching for and digging up buried lids at every service visit, the crew simply unscrews a lid at the surface. Most risers are plastic, though concrete versions are also used, and each opening on the tank can have its own riser.

Benefits of adding risers

Risers cut the time and cost of every pumping and inspection, since no digging is needed. They make it easy to check the effluent filter, spot problems early and show inspectors the tank during a home sale. They also protect your lawn from repeated digging.

What to expect on installation day

Most riser installations take a few hours. The tank is often pumped at the same time so the crew can inspect it while the openings are exposed. Expect some digging around the lids, which is backfilled when the job is done.

Keeping lids secure

A secure lid is a safety requirement, not an option. Check lids once in a while for cracks or loose screws. If a lid is damaged, cover the opening and call for a replacement.

Is a riser worth it

For most homes with buried lids, yes. The savings from not digging on every visit, plus easier inspections, often cover the cost over a few pumpings. Ask your septic company to compare the cost with what you pay for digging now.

Choosing a riser installer

Look for a company that seals risers properly to keep groundwater out and uses secure lids. Experience with tanks common around Medina and Clyde Hill, Yarrow Point, Mercer Island helps them match the right parts to your tank.

Plastic or concrete risers

Plastic risers are lightweight, easy to trim to height and do not corrode, so they suit most existing tanks. Concrete risers are heavy and durable but harder to install and can let in water if joints are not sealed well. Your septic company can recommend the right option for your tank.

After the risers go in

Make a note of where the lids are for future owners and service crews. Mowing around them is easy if they sit flush, and they make it simple to check the effluent filter or water level. Report any loose or damaged lid to your septic company.

Signs your tank needs risers

If lids are buried, if the crew has to probe the yard to find the tank, or if past visits left holes in the lawn, risers will help. They also make sense if your system has a filter that should be checked often.

Risers on King County septic tanks
