WHAT OUR CUSTOMERS SAY…

“It is so nice to see you guys are still rocking and providing the best service for unique plumbing parts. I first used you guys 20 plus years ago when my brother turned me on to you. I live in Nashville now and was searching the entire region for a particular cartridge and you are the only one that had it. Hands down there's not many like you and you've always provided a great service and I'm glad to see you doing it now even online! ”

The B&K ProLine Series 888-221RP is a multi-size replacement drain cap pack designed for stop and waste valves, ball valves, and gate valves with side overflows. It serves as a universal repair kit to fix leaking or missing bleeder caps on outdoor spigots, main water shut-off lines, and irrigation systems.

These caps are used to seal the drain ports (also known as weep-holes or side overflows) on valves, which allows the non-pressurized side to drain without fully removing the cap. This is particularly useful for maintenance or winterizing plumbing systems.

WHAT OUR CUSTOMERS SAY…

“These people were extremely helpful in taking me through replacing a 25 year old hard water frozen cartridge on my Philrich sink faucet. They were able to identify the correct part I needed from a photo I sent (I had it figured out wrong). I was pleasantly surprised they had an obscure part like this, but they also told me how to extract the old one when I couldn’t get it out. They said to unscrew it after I had concluded from YouTube the old cartridge was supposed to just slide out. It threaded out as they said and saved me buying a cartridge extractor and a hernia. The whole experience has been excellent. ”
