Stopped by a job we did on the East side about 2 years ago this morning (we transitioned a shower valve install off 3/4" copper branch lines with 3/4" inch Cash Acme push-on tee's to red and blue...

Recently discovered that a number of PEX tubing manufacturers do not recommend the use of Shark Bite and other push-on fittings with their tubing.

Wirsbo/Uponor, Zurn and Viega in particular,...

The white piece is meant to be used with PEX tubing.

As far as the cap goes, make sure you have a clean and straight cut and then simply push the cap on with a slight twisting motion until you...

There are several kinds of tempering valves for a number of different applications:

A tempering valve can be installed on a indirect fired HW storage tank (in combination domestic/hydronic...

Disconnect the supply hose and check both ends for plugged screens -- If screens aren't plugged or present, then check the machines water inlet for debris.

Those covenants are for the most part a joke.

We have a law firm here on the Left Coast that is thriving, in no small part, because of the vagueness of these covenants.

The problem is, for...

I'm all too familiar with the 'busybody' mentality. I had to threaten one board member with a no-contact order after he refused to accept my findings and then harassed me over the phone for several...

All good points.

When you say you would pay the bill, would that be you paying the bill out of pocket -- Or would that be you in your capacity as HOA President paying the bill out of the...

I think you'll find that your situation is the exception, rather than the rule, Ball.

I've served as a representative for parties on both sides of situations similar to the one described by the...

Having never seen gasketed PVC pipe smaller than 3", I'm guessing it must be a regional thing.

In my neck of the woods, we don't use gasketed piping or fittings for high pressure applications, we...

Tracing a leak down can oftentimes require a great deal of exploratory 'surgery', so having a Plumber out more than once isn't all that uncommon.

Should you have an opportunity to examine the...

I think he could probably lower the height of the ballcock in small increments until he finds the right balance between inflow of the RO system and overflow through the overflow tube in the WC.

The screw on the side is designed to snap off once it is tightened to prevent the removal of the VB.

It's a fairly course thread, so I generally remove it with an easy-out and the appropriate...

Right -- And pretty much every person who responded cautioned you not to proceed with this project and even stipulated why they were opposed -- Nobody here is going to rubberstamp a project they deem...

T'would appear you are more interested in seeking validation for your own ideas than you are in seeking advice.

Not a big deal, really, just an observation.

Nearly all commercially available ABS pipe is foam core (cellular core), which has a lower pressure rating than both foam core and solid core PVC pipe.

If corrosion is the only drawback to using...

And this is precisely the reason why most jurisdictions have banned air tests for plumbing systems and instead require hydrostatic tests.

All it takes is one small weak spot in the extrusion...

Nonsense.

Nearly every DW air-gap leak I've ever encountered can be traced back to shoddy installation practices.

The usual suspects are:

Stressed hose connections which pull down on the...

Is there a Reduced Pressure Backflow Preventer or Double Check installed?

Milo:

You mentioned an access panel earlier in this thread -- Is that a personal preference or a code requirement in your area?

Also, FYI the Governing Parties behind the UPC are mulling over...

I'm with Milo -- Mortar mix is what I usually use as well.

I'm not sure I understand why it is you want to reduce the pressure.

Exactly what is the application here?

It's extremely rare, but I've seen a few drain lines plugged with uric crystals during bar remodels over the years.

If it's possible to install one, I'd suggest installing a 'Backwater valve' in an accessible location somewhere between where the waste pipe exits the house and where it enters the septic tank.

You really need to specify which urinal you will be using -- As well as its application.

Will it be wall mount or floor mount?

Integral trap or exposed trap?

Exposed or concealed...

OTOH, depending on the age of the home and its location, your kitchen sink might be plumbed into a French Drain, in which case the French Drain might be over capacity.

You might do better to pump the water to a rain barrel positioned as close to the washer location as possible and then allow gravity to do the rest of the work with soaker hoses or drip irrigation...

If it's going to be run horizontally through the cabinets, then it will be below the flood rim of the sink, which would require the use of drainage fittings.

Most of the Legend FF hose bibbs rely on a easily replaceable 1/4 turn ceramic cartridge.

Replacement is as easy as loosening the packing nut and pulling out the stem -- The cartridge is at the...

If you are going to run the vent horizontally through the cabinets as well, hold it as high as possible and use drainage fittings (long sweeps) where applicable.

I've installed quite a few of the D'Mand pumps recently and most of the customers have opted for the 'doorbell' means of actuating the pump.

The systems I install rely on a continuous loop from...

You would likely damage the tank if you connected the low pressure outlet of the tank to a higher pressure sink feed.

The inlet of a Insta-Hot tank has a flow restrictor to reduce the volume and...

Is there a water softener or a reverse osmosis system installed?

Acidity in the water after treatment is a prime culprit when it comes to copper tube failure in such a short time span.

For your future edification, Tom -- The snake you used (if the same one in your photo) is designed for cleaning out sink drains, not water closets.

How long are the branches?

Are they insulated?

If the branches are 25' or less (even with a vertical rise of 8 to 10 feet) and the branches are insulated then the wait time at each outlet as...

Or, for about $250.00 you could install a single Laing Autocirc circulating pump under the sink furthest from the HW Tank and circ the entire house.

The Takagi TH-2 is compatible with the Uponor D'MAND circulating pump

I just wrapped up a 5 bath house on the East Side where 4 of the 5 W/C's centered on 2"x12" TJI's, all 5 showers centered on TJI's and 6 of the wet walls (including the laundry room) centered on...

I generally ask what the finished floor height will be and then cut and hole-saw a piece of plywood to bring the flange up to the proper height at the rough-in stage.

The blocks are then secured...

Sounds like a worn flapper valve or possibly a worn Douglas valve.

If we're talking only one joist that happens to be centered on the new WC location or that is too close to make the initial bend, then a competent Carpenter should be able to head the joist off w/out...

Milo -- Has California banned AAV's altogether, or are you allowed to use them in some instances with prior approval?

I'm pretty sure Saint Louis has adopted the Uniform Plumbing Code, beardz, in which case you can likely use an AAV with prior approval of the Local Authority.

Don't get me wrong, you seem to have...

It really depends on the manufacturer of the tub and the composition of the tub.

Enameled steel tubs are generally exactly 5" from flange to flange.

Cast iron tubs are generally a little...

I followed the thread from start to finish, noting the many misgivings and reservations of those who walked you through the installation.

That it isn't going to be inspected and that you...

As one who can appreciate the distinction between a Master and a Journeyman under the UPC (the strictest Plumbing Code in the Lower 48), I offer my congratulations as well.

BTW, I'd start...

OMG.. .

That is *SO* wrong on *SO* many levels.. .

All those code violations -- And yet you bothered to use treated plywood.

>shrugs<

Well, if it's going to be a permanent...

Yes, Milo, it sure is. :)

Did you bevel the outer edge of the pipe before you installed the stop?

If you cut the pipe with a tubing cutter then it likely left a ridge on the pipe, that ridge will often times just push the...

Do you already have the toilet, or are you still in the shopping around phase of this venture?

At 45psi I would recommend going with a wall mount toilet with a pressure assist tank instead of...
