If your grinder pump is out of warranty and you are in need of service, call Weston and Sampson directly at the number below. Only units that are out of warranty are covered by the Town. Grinder pump repair or replacement due to misuse or abuse (see attached insert) will not be covered by the Town.
Note: It has been found that undissolved powdered laundry or dish detergent may cause unnecessary grease build up. Grease removal is the responsibility of the homeowner.

For in-warranty repairs contact:
E-One grinder units only – call FR Mahony: 508-765-0051

All grinder units and systems will remain personal property. By requesting service you are authorizing the Town and/or its agents to enter your property for the purpose of providing inspection and repairs.

Regarding Homeowner Abuse Determination
From Mike Vosnakis, Sewer Superintendent:
"I reviewed our notification procedure with Sharon Boyer who handles the correspondence [with homeowners]. I've also asked her to make sure that this correspondence is sent certified as requested. The processing timeline to date has been as follows.
a. W&S performs a repair.
b. In 15-45 days the DPW receives a monthly invoice with individual repair call invoices done during the monthly cycle. A few times it has taken longer. In some cases an additional visit is needed to complete the repair which would fall in the next billing cycle.
c. After a copy of each repair report is made and added to the residential file, I receive and review all invoices and determine if any are deemed misuse/abuse and require a bill to homeowner. This may take up to 30 additional days but normally is done within 15 days. As mentioned, there have been very few during the last 4 years.
d. Within a week, a notification letter (letter template attached) along with related repair documents are sent to homeowner.
e. 1-5 months (next billing cycle), a line item would appear on homeowners next sewer bill. During this time disputes and/or potential adjustments with sewer bills are handled on a case by case basis. Disputes begin in the Sewer Division. If necessary, they are elevated to the DPW Director and/or Town Manager.
f. With Sewer bills there is no time limit for resolving disputes but interest charges would normally apply.
