So how far did Richard have to travel to meet with these people and tell therm... "Call an expert!"???
Rob L.
Interesting how the doctor brags about his job, says how easy plumbing must be, and then disappears when it comes time to actually work.
Aspen Water Solutions
Interesting that they replaced the Rainsoft valve with a different brand.

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!
Chris Helms
Great Video!!! Thank you, exactly what I was hoping for.

Woah! The technician is using an Acqualung wrist watch!

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

Looks like roe

should have used SS flex lines. makes servicing the filter much easier.

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!!

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?

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!

No more Salt Bridges ,

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?
Charles Damery
Definitely not in New England.

Why is 1080p the only option?
Andrew Davis
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.
Whats the point of this shot 2:31 to 2:37 ?
y is the Water Softener outside? i have 1 & its in the basement.
The husband dissapeared ;) 
Is the that a fleck head unit?
They need a filter or reverse osmosis to take the chlorine out of the water.
Dan Nichols
Lol is that cpvc?

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.
