Question DetailsAsked on 8/9/2017

How much should hydrojetting three kitchen drains cost in west Los Angeles?

Plumber tried snaking, but backup persists. He had in the past recommended hydrojetting because I had needed snaking every 2-4 months. He wants to charge $675. There are 3 drains in this kitchen.

Here is a previous Angies List article on that - `

However, why 3 drains - I would suspect strongly that if you have three drains backing up, that a common line or trap which they feed to is the source of the probloem - commonly the trap or the commonly horizontal stubout from the wall leading from the trap getting clogged with fibers and grease. Did he remove and clean the U-shaped trap under the sink and swab out the stubout pipe ?

Could be you really should be getting a Sewer Cleaning contractor - and for $675 you could usually get the entire sewer/drain line system routed or jetted out, both inside the house and to the septic tank or street, so I would get another couple of quotes. Drain cleaning specialty firm are commonly around half the cost of plumbers for that work, and generally have all the equipment needed to do it right. I would expect something in the $150-250 range would cover the cleaning, including all 3 of the drains if needed (though I doubt that is the case). And hydrojetting is not my idea of a good way to clean kitchen drains - good way to make a horrible mess.

Note that snaking can clear a clog enough to let the backup drain out, but generally does NOT effectively remove any grease and soap scum buildup which may have been the cause in the first place. If it has been a long time since your sink drain pipes have been cleared out, a complete cleaning (brush routing or disconnecting and swabbing out) may be in order, because organics and soap scum and grease will build up and reduce the pipe diameter over time, commonly needing cleaning out every 20 years or so, but more frequently if a lot of hot water (i.e. dishwasher) does not go down those drains or if you let a lot of food material or grease go down the drain.

Also - if this is a bottom floor kitchen, your problem - especially if getting any backup in any other drains like shower./tub, might be a partial blockage in the sewer line, not the drains themselves. Sewer lines clog up with grease and fiber which reduces their diameter so eventually you start getting backups when large quantities of water are dumped (like full sink, clothes washer, full tub) and eventually clogging of the line which can lead to general backup of sewage. your sewer lines (at least the underground portion) should normally be routed or jetted out (I prefer full-diameter scraping with a router unless you have clay drain tile or deteriorated fiber or casdt iron sewer line, in which case jetting is less likely to damage the pipe.

You can find a lot of previous questions about drain problems and solutions and typical costs in the Home > Plumbing link under Browse Projects, at lower left.
