Richard and a local expert helped a pair of Florida homeowners repair a broken water softener. A plastic basket inside one of the tanks had ruptured, allowing “resin beads” to clog water pipes and fixtures inside the house. To fix the problem, they cleaned the inside of the tank and installed a new “control head” and resin beads.

  1. Over many years I have learned so many things. Both for my own remodeling, and to help others with their remodeling jobs. If for nothing more than to get the verbiage correct. Its very helpfull to be able to name the items being used. And to have a understanding as to how they work, or operate in your home! The Experts on these serieses, are extremely helpful in how there take the time to both show and talk we the viewers through the processes! This is extremely important to have a correct remodeling job, but to understand how it all happens! Thanks to everyone involved with THIS OLD HOUSE!!

  2. you never use block salt, u dont have enough contact time with salt and water around it, amd that 5600 fleck they r using is a generic head, use hague products, or aqua systems both made in the USA all the way every part

  3. Thank you guys for walking through this process. I don't think anyone else here on YouTube ever walked their viewers through these steps and explained the process in such great details. You got yourself a subscriber. Keep it up!

  4. It's easy to forget how important water is in our lives. Of course we need it in our diet, but in our homes, it's a tool–a fluid medium that carries material from one place to the next. And one of the reasons it does this job well is that it's very good at holding things, either by suspending them or dissolving them.

    Unlike most tools, though, water doesn't come with an instruction manual. If it did, you'd know why the dishes you thought were washed are covered with spots when dry, why the water in your shower leaves a film on everything it touches, and why what you thought was clean water has clogged up your plumbing system.

  5. Has anyone had iron bacteria contaminate the tank? If so would cleaning the system and replacing the bedding be sufficient enough to get the system back to functioning? Just bought the house and its an expensive system. Don't have money to spend on a new system.

  6. my area charges about $250 to do this maintenance… but from the looks of it, it looks straightforward enough to do this on our own. am I missing anything, or should a specialist be hired to do this work?

  7. Richard asks the expert: What does Grace have to do to make sure this thing runs for the long haul? Answer: basically, just keep salt in it. 30 seconds later he says to have a maintenance guy come out once a year. For what?

  8. So these professionals glued the PVC manifold back together without unions to allow disconnect and recharging in the future of the system. BRILLIANT….job well done!

  9. Before going through that process, I would recommend purchasing a bottle of Res Care Resin Cleaner and a pack of Sani-System Water Softener Sanitizer. You can pour both down the brine well and the regenerate the water softener. This could bring back the resin to life and also sanitize water softener.

  10. this is the only video I've seen where a gravel bed is added. Is this an optional thing? Best practice? How much gravel do I add? If you don't add it what happens?

  11. Bogus, replace the fitter basket for $30, do a clean/regen and you've repaired it. 10 year old head? i know people with 40 year old units still working great with regular maintenance. Video should be titled "how to replace a water softener"

  12. I did my own with new resin I bought off of eBay for $92. This new resin should last about 10 years.

    Replace the control head? Not necessary.

    Annual service? Definitely not necessary.

    Just keep the brine tank filled with salt.
