Valve Tech / Re: Question on our CSV1A

« on: May 06, 2024, 09:19:53 AM »

Just a quick follow-up. The CSV held properly today at 44 psi as set.
Only guess I have is I did not tighten the lock nut.
Thanks again.

Appreciate your time.
I'll now monitor how the CSV functions while the shower is being used and see if my adjustment holds.
I'm positive that I'm the only one messing up the plumbing here.

So ... if I'm understanding ... the CSV "setting" may reduce itself as the spring becomes "weaker" over time ? And that would necessitate an adjustment on the tension ?

OR .... The pump installed 4 years ago is not providing the same flow ?

The system starts the pump at 30 on the gauge and off at 50 as usual indicating to me the gauge is still accurate.
I did note the locking 9/16  nut was not tight. Would it be possible the adjustment screw "backed off"  through vibration ?
What malady does the rebuild kits repair ?

Mr. Austin.... We did our semi-annual maintenance on our water heater & while the tank was refilling I noted that the operating PSI was at about 35. Today I adjusted the valve up to the original setting of 45 psi.
My question is does this variance in the set pressure demonstrate the unit may be due for a rebuild kit ? The CSV was installed November of 2020.

No ... the first attempt was with the PVC connectors and because they would not seal ...  I ordered some stainless from Supplyhouse.com thinking the threads would be "better".
Fifty years ago I made a living as a machinist having gone through the GE Apprentice program and I have to admit ......... this failure at the plumbing stuff is indeed frustrating.

You've been more than generous ....... Many thanks.

All the Rectorseal I can find on line is "Soft-set or flexible-set". I currently have Oatey "Great White" brand.
Is there a better option ?

My luck is not shining through.
With the new second CSV and stainless steel barbed fittings the leakage is more pronounced now than with the first edition.
And I was very cautious in trying to do everything correctly. Initially I studied the the valve and fittings and had issues getting the currently leaking side to start. I took a closer look and the threads were deformed as the picture shows. I took a razor knife and carefully shaved the threads at the specific location so the 1 1/4 stainless threaded properly.
This well is into my workshop so I have no urgency until the wife's flowers start to grow. I think it best to leave it alone for a week or so ... because Bob really does have a temper from time to time.

Incidentally .. when I called your facility the young lady that answered the phone was truly a joy to have a conversation with .... a remarkably pleasant personality over the phone that was immediately appreciated ...............  with the best "Texas" accent I've ever experienced.

A true asset.

Valve Tech / Re: Guidance on a CSV125-1 installation

Mr. Austin .... If your experience points to the fittings I will order a couple Stainless from Supplyhouse. The valve is functioning as it should and I imagine my leaking issues are all about my installation "technique".
Every time I try to go cheap it bites me in the butt.
I should have ordered the CSV1A like is in the house to begin with.
Many thanks for your guidance.

Well ... No success. I did confirm the fittings are not bottoming out.
I returned to the project last Thursday and tried again without success and decided to leave it be to avoid further frustration.
Today I tried twice with just the teflon tape and finally gave it a third try with the pipe dope over the tape. All three occasions resulting in the same drip generated on the exit side.
Should have stuck with the metal valves.

Thank you. We'll give it another try this afternoon.

Valve Tech / Guidance on a CSV125-1 installation

« on: April 13, 2021, 12:54:59 PM »

Hello once again.
I received the 125-1 today and it is functioning as it should.
I do however have leaks i.e. drips at both ends ... the exit end being worse. I have taken it apart and reassembled three times without success getting the drips to stop. I've used the standard white teflon and tried the .0035 gray as well.
I am using 1-1/4 pvc x 1" barbed fittings and now wonder if the "plastic to plastic" may be part of my problem.

Are the brass or stainless a better option to get a seal ?

The red collar on the valve was very loose on receipt so I hand tighten that .... I do not think that's the source of my leaks.

Valve Tech / Re: Adjusting the CSV1A at installation.

Now our replacement is complete.
On Thursday we had the well pump replaced with a Gould and the check valve is holding solid. The CSV is operating at about 43 psi and we have no leaks. Found out the level of our 200 foot well is at 113 feet .... so we have a much smaller reserve ( 130 gallons ) than we thought we had. The water level used to be at 30 feet but that was 40 years ago.
We let the system rest for a full day to get the mud and other crap to settle in the well and now we will live with "silty" water for awhile. Just have to remember to wet vac the dirt, rusty crap & silt out of the toilet tank in a few days.

Pumps, Wells, Tanks, Controls / Re: Need help again ... Valve not working for our application..

I've taken a gallon water jug and measured the GPM with the cold side opened approx. to where is normal for a shower. The result was about 2 GPM ........ the shower head has no restriction or water saver feature on it.

Would reducing the "hold" setting on the CSV be of any value to get the valve to function ? The relation between the GPM & the PSI is what is a little confusing.

Could you provide any guidance on the appropriate pump size ?

I would really appreciate your opinion.
If I run the cold water at our sink and tub ( full open ) at the same time the valve will hold at about 43 psi. Normal usage for us is just the outlet at the shower being used while the wife or I take a shower and then the valve does not effect the pump cycle ..... it functions as if the valve were not there at all. ( I'm guessing not enough flow ... The cold side is probably only open less than half way to balance the mix with hot water ) 
Our well is 215 feet with 1 gpm with level 30 ft. from surface  per p/w provided in 1992 when the pump was installed. I calculate we are using an approx. 200 gal. reserve in the well pipe.
The current pump is a 3/4 Myers motor and I don't know the GPM of the pump.
I am having the 28 year old pump replaced in the near future primarily because of a suspected leaking check valve. ( well cycles once per hour approx )  We have a mobile home with 5 outlets i.e. Kitchen sink, bathroom sink, toilet, shower and outdoor spigot.
Questions are : What size and GPM pump would you recommend as a replacement ? ( The well company uses / sells Franklin pumps which show 7 or 10 GPM pumps available on the lower limits ).  Is it possible to increase the "flow" to the shower outlet ( 1/2" polybutylene piping )  to enable the CSV to function ? Is it possible to adjust the CSV so it would hold at a lower pressure such as 35 psi with the low flow rate ?  ( or are we in a "it is what it is " situation and the CSV was a wasted effort )
