Qest Plumbing San Diego

Qest (polybutylene) plumbing was a popular water supply system in the 1970’s and 1980’s. Polybutylene pipe (sometimes called PB or Poly-B pipe) is easily identifiable since it is non-rigid, usually gray but at times silver or black, plastic pipe. It is not PVC or CPVC, which is a rigid white or off-white plastic pipe. It has been used in approximately six million mobile homes, apartments, houses and other structures throughout the United States and was sold under the popular names: Qest, Thermoguard, and Flex-Temp.

A significant number of PB plumbing systems began to experience problems with leaky fittings by the late 1980’s. Therefore, the system was discontinued. Although this type of plumbing is no longer available for new installations, Bill Howe Plumbing carries all necessary materials to repair these systems.

We also have extensive experience to conduct a total re-pipe or replacement of Qest systems if you would like to update your current plumbing at a fair price.

We have been offering excellent service at reasonable prices throughout the San Diego community for more than 35 years. Unlike the plumbing companies working to avoid cost conscience customers the Howe family built a business embracing these customers needs. It soon became clear that homeowners needed the same cost advantages. So, since we are a family owned company, there is no giant corporation headquarters demanding high prices, which in turn, means low prices for you!

For quality and affordable plumbing services you can trust, call 1-800-BILL-HOWE (1-800-245-5469), the San Diego plumbing service leader.

What David says about us

Service for new garbage disposal. My ancient garbage disposal quit working, went online to get Bill Howe’s number, immediately received and accepted chat to describe my needs. Prompt call back to schedule an appointment, service tech Allen was out same morning, which was important to fit my work schedule. Job estimate was clear, work done fully to my expectations, area left clean, and price was very fair.
I was not surprised — I have used Bill Howe plumbers for several other tasks in the past. I have always found their staff to be helpful, attentive, and the plumbers very courteous and capable.

I have been using Bill Howe since the late 1980’s, their service has always been excellent, plumbing, heating and restoration. I am most impressed by the integrity of their employees, not only do they know their work/skill, they do not waste time, they are so efficient, they are so helpful and they are a true “service”!

What Mira says about us

Bill Howe never fails us! We had a drain overflow, and Scott came (on a Saturday) to look at it and offer solution. He was punctual, professional, and extremely helpful. I should also praise the main office for always being helpful and always finding solutions. Very grateful to have you in San Diego!

Restoration & Flood

What Ed Gohlich says about us

Cory was our technician on this job. We had a time sensitive repair issue and Bill Howe understood and assisted with getting the job done quickly.
Cory was on time to start the job and finished it quickly. Upon his leaving our home he’s was courteous, very knowledgeable, explaining what the problem was and how he fixed it. Very good communication and this is the way it’s has always been when we use Bill Howe plumbing.
Great company to work with.
Thanks Cory.

What Bridgett says about us

I am extremely happy with the service we received from Bill Howe Plumbing. We were given an incorrect diagnosis of our main sewer line from another vendor, but Bill Howe’s servicemen came out for a second opinion, correctly diagnosed our problem and resolved our back up issues. We will continue to use Bill Howe for all our future plumbing needs!

Thank you Bill Howe Plumbing.
