Common
COMMERCIAL BACKFLOW PROBLEMS

  • A letter from the city saying your backflow test is due.

    We test, send in the paperwork and fix anything that needs it before the deadline, so your water stays on.

  • Your backflow device didn’t pass its yearly test.

    We clean or replace the worn parts inside, then test it again so you get a passing result.

  • Water running or spraying from your backflow device.

    That usually means a part inside has worn out or clogged. We repair it before it floods the area.

  • A cracked or leaking device after a cold snap.

    We replace freeze-damaged devices and show you how to protect them before next winter.

Frequently Asked Questions

What is a backflow device, and why do I need one?

It’s a valve that stops water from flowing backward out of your building and into the city’s drinking water. Businesses run things like boilers, soda machines and sprinkler systems that could contaminate the public supply if the water ever reversed, so the city requires one.

How often does it need to be tested?

Once a year. Washington and Idaho both require a yearly test, plus a test any time the device is installed, repaired or moved.

What happens if I miss my test deadline?

The city can shut off your water until the test is done. If you get a notice, call us and we’ll get you on the schedule.

Why is water coming out of my backflow device?

A short burst now and then can be normal. A steady stream usually means a part inside is worn out or clogged. Either way, give us a call and we’ll take a look.

Will testing shut off our water?

Only for a short time. We schedule around your open hours and let you know before we turn anything off.

Do you send the results to the city?

Yes. We file the paperwork with your water department and send you a copy, so you have proof it was done.

Do you use an answering service or AI?

Your call will always be answered by a real person, even after hours and on the weekends.

What if I can’t wait at home for a plumber?

We are happy to call when we are on the way so it gives you time to meet us there.

Can you give me a price for my job before you start?

Absolutely! Once our plumbers evaluate the problem, they will give you a total price before beginning the work.

Do I have to make a second appointment after the evaluation to get the work done?

No. For repairs, we can stay and do the work at the same time. Larger jobs and/or remodels will be scheduled in advance.

When scheduling, will I be given a time?

We schedule our calls in a two hour window and call when we are on the way, so you stay informed.

Do I have to pay at the time of service or will you send a bill?

Glenrose expects payment at the time of service. We take Visa, MasterCard, AMEX, Discover, cash or check to make it as convenient as possible for you.

I’ve had other service providers ghost me when I had a problem with the work that was done. How do I know you will answer my calls if I have an issue?

Glenrose has been serving our community since 1987 and will continue to do so. We warranty our products and installations for one year, but will always be here to help navigate your plumbing needs. We are just a phone call away!

How do I reach you if I am having an after hours emergency?

We can always be reached at our office phone number 509.385.8915 or by texting 509.385.8915.

What if I don’t like the fixtures you have with you?

We work with several local plumbing wholesalers where you can view products in a showroom. Once you have made a choice, we can pick it up and install it for you.

Will I be charged extra if the plumber has to leave my job to get parts?

No. Your parts are included in the up front price given at the beginning of your job.

Can I supply my own parts?

We are happy to install customer supplied parts but cannot provide a warranty on parts we do not provide.

Can my child meet the plumber if I am unavailable?

Whoever meets the plumber must be over 18 years old.

Is it okay for my pets to be out and about when the plumber is on site?

We love fur babies but ask that if they would be uncomfortable with a stranger, please limit the exposure as needed for everyone’s safety.

Glenrose Guarantee

We guarantee our work will be completed with a high standard of care. As a family owned & operated business since 1987- we’ll do what it takes to make it right.
