Enclosed is a summary of their findings. Please review the report and <br /> contact us with any questions. <br /> The report identifies deficiencies in your plumbing, sewer and drainage system. This <br /> includes: <br /> • The two downspouts in the back yard are connected to your side sewer on the <br /> upstream side of the backwater valve. This could cause your basement to flood <br /> during a surcharge event with water from the downspouts. <br /> • The backwater valve may not have been seated properly due to dirt and debris <br /> that was stuck between the flapper and the seat of the backwater valve. This <br /> would not allow a tight and secure fit during a surcharge event. <br /> The downspouts connected upstream of your backwater valve should be disconnected, or <br /> rerouted so that they connect downstream of the backwater valve. If you would like <br /> further assistance with this drainage modification please contact Brian Doolan or Grant <br /> Moen. <br /> We recommend that you inspect your backwater valve 4 times a year to ensure that it is <br /> clean, undamaged and that it is working correctly, as indicated in the maintenance packet <br /> you received previously. If you require an additional maintenance packet or a <br /> demonstration please call and we will provide assistance. <br /> CITY OF EVERETT • 3200 Cedar Street • Everett, WA 98201 • (425) 257-8800 • Fax (425) 257-8882 <br />
