"Robert and Franky were great. Just nice people to work with. Our water tank sprung a leak on a Monday, and Facilities Plumbing & Drain gave me a quote and finished the work on Tuesday (only 24 hours without hot water!). The cost was in the range of other quotes I got (not the cheapest, but definitely not the most expensive, and they installed a top end Rinnai unit). Given the quality of people I interacted with, the work product, and how quickly they got the job done, I would say I got very good value for the price I paid. I would definitely hire them again."

"We highly recommend Green Arrow Plumbing. Our clogged drain was due to the corroded cast iron drain pipes original from 1957 and Cornelio replaced them in short order. While he was here, he also fixed two toilet flushing problems which two handymen had been unable to do. Cornelio was very knowledgeable, his rates reasonable, and it was a pleasure to work with him."

Customers say: True professional

"Francisco installed a new vanity top with double basins on an existing cabinet. He first carefully and skillfully removed the old vanity top with back splash without damaging the wall or cabinet. We are very happy with the work Francisco performed. His work is very professional and his fees are very reasonable. We definitely recommend Francisco and will be using his services again for future plumbing projects."

"He was wonderful! We had several issues with our toilet and system being backed up because employees/clients flushed items down the toilet over several months. Each time we had an issue, Jess came out promptly and fixed everything. He is always friendly and helpful. When a large section of our pipes needed to be replaced, he fixed it, did an excellent job AND even came out over the over a holiday weekend! We will continue to use Jess whenever we have plumbing issues!"

Toilets FAQs, answered by experts

To drain a broken toilet, place towels or plastic sheeting around the base in case of splashing or overflowing. Next, shut off the toilet’s water supply, usually via a valve on the wall behind the toilet. Begin flushing the handle to remove as much water as possible from the tank and the bowl. Don’t flush the toilet if it’s clogged, though. From there, use a large sponge to soak up any remaining water and wring it over a bucket. 

If you need to repair part of your plumbing, it will cost an average of $330. The cost of plumbing repairs is influenced by several factors, including the type of drain and the specific repair needed.

If you notice water coming out of the bottom of your tank or the flush handle, you obviously have a leaking tank. Water on the side of the tank can indicate cracks. Other signs include the toilet running and flushing without anyone touching the handle, needing to jiggle the handle to make the water stop after flushing, or needing to hold the handle down to empty the water tank.

Most toilets have a 12-inch rough-in or hole, but some have 10- or 14-inch holes, which means that not all toilets fit all setups. Knowing how to measure the rough-in is essential, so you purchase a toilet that fits the existing drain hole. It can be costly to have the rough-in moved, and most stores don’t accept toilet returns.

A bit of water in the bowl can help unclog a toilet, especially if you're using a plunger. However, if the bowl is full to the brim, you'll need to strap on gloves and remove some of the wastewater in a cup or container so it doesn't overflow when you try to unblock the pipe. If you're concerned about it filling further, manually close the flapper in the toilet tank or turn off the water supply to the toilet.
