Attach pergola to patio -- worried about gas lines under patio

Turbo1Ton
How much of that 6.5" bolt must be embedded in concrete? Is that 6.5" of embedded length or like 4" embedded with a 2.5" protrusion. If it is 6.5" embedded, you may be looking at cutting out sections of the decking and pouring a deeper base. The anchor gets its holding strength from being fully embedded into the substrate. In this case if the slab is only 4" thick, you effectively have a 4" anchor bolt.

Is my SWG failing and question about Hayward

It is a sign the cell is getting depleted.

You can run it till it dies or replace it at your convenience.

Extended life is supposed to have stronger plates and last longer. YMMV.

Thanks. Followup question. The cell continues to run. As I review replacement options, can I get it to keep working by every morning setting the instant salt to the correct level (since it initially reads correct?)

Pool opening

T
Ive always had trouble relying on my swg to bring fc up high enough upon opening, and Ive tried it a few times. While the cell should make enough fc running at 100%, it hasn’t accumulated. I’ve never been sure if this is because the water’s been cold, or because Ive got something growing in there (or both)

I’ve had much better luck using LC to bring FC up very high upon opening - approaching slam levels, making sure it passes an overnight chlorine loss test, and relying on the swg from that point on.

Resurfacing with River Rok – Need Supplier & Tips for DIY

M
Hi everyone,

I’m planning a resurfacing project for my in-ground L-shaped pool L (28’ x 25’ x 10’ x 14’, 3.5”to 6” depth) was which originally built in 2009.

I’m looking for reputable suppliers in south Florida or online) where I can purchase River Rok, as well as the required bonding agents and a Hayward Super Pump® XE 2.25 SP2615X20XE.

Suggestions for trusted sources for waterline tile, coping, and startup chemical kits to make this as smooth as possible.

Thanks in advance!

How quickly does your filter pressure rise?
Click to expand...
When first vacuuming out algae that was green and visible, the filter would need to be cleaned/changed after every vacuum due to pressure. This current filter cartridge was placed after the pool turned cloudy white and began on 15psi. We are now 3-4 days with constant running and it is at 16-17psi.

Mixed Instructions - VS Pump & SWG

What is your filter PSI as the heater is turning off and you are increasing the pump speeds?
Click to expand...
Filter psi was at 10 when at 2200 rpms and stays around 10 up to 2600 rpms. The other day it got to 20 because it was dirty from the gook. That's when I did a full clean to try and eliminate the filter as a bottleneck.

Right now at 2600 rpms it's maybe 11psi. When running lower speeds like 1800 rpms psi is only like 5

Sand filter problems after sand change and lateral replacement

elaine murphy said:
Looking for suggestions. I recently changed sand, found cracked laterals, and replaced both as well as the key handle on my Hayward Sand filter. I did a 2 minute backwash, and found a lot of sand that didn’t dissipate with a rinse. Backwashed a couple more times, no change. For next 2-3 days I found decreasing amounts of sand in my pool, which cleared up til I backwashed a week later…again, site glass clear during backwash and full of sand during rinse. Found some sand in pool when vacuuming with bot, seems to be decreasing amounts daily. Any suggestions? I added water before placing laterals, standpipe lined up fine when I put multiport valve on. Puzzled and frustrated. TIA!

Sand coming out of the jets is getting through the laterals or got in during replacement.

Sand coming out of the waste port during backwash is more “normal” if it was overfilled.

De filter close to 20 years old

HermanTX
It could be your grids are full of grime. Have you replaced the grids?
Older filters had fiberglass on inside of the housing which can deteriorate over time.
I did a replacement with another DE filter. Although the pipes lined up from the MPV, there was a slight height difference. I had to put the new DE filter on stepping tiles about 1 inch high. So make your measurements and be sure it all fits.

Moving to a cartridge filter will require you to move the plumbing.

Why is my pool eating chlorine?

B
CapeCoral said:
The pool got a little cloudy and I thought my salt cell was not producing well. My other numbers are ok (pH 7.5, TA 110, CH 300, CYA 60.) I tried SLAMming the pool the past couple of days and I hosed down the cartridge filter. Phosphate test strip showed nothing. The pool looks great - crystal clear. CC is 0.5. But overnight again chlorine went from 28 to 21 (I did have a few people in the pool before I tested before bed.) What am I missing??View attachment 644982
Click to expand...
FC of 28 is pretty far over the SLAM level of 24. Don’t have people swimming in that. The OCLT also tends not to work as well when the FC is over SLAM level. Try again when it’s back in normal range and no one is swimming.

What did you do to your pool today?

Takeaways:

- I try to convince people to have a spare sump pump on hand for pool pad shutdown emergencies. Well... here's a great example of why. There are limitless reasons you might lose your pad functions for some number of days (or weeks), even for something as unforeseeable as this!

- Every plumber or DIYer knows NOT to work above a drain without making sure you can't drop anything you're working on into it. Duh!! (How many times do I have learn this?!)

- Since all it takes to shut down your pool pad for a few days is losing or mangling your filter plug, maybe having a back up in stock is prudent. I'll have one now.

That all said, I did get my filters cleaned. It was surprisingly easy. They had a lot of particulate gunk, but nothing staining the media, it all rinsed off, with just water, as fast as I've ever done it. And my new filter washing stand extender worked better than expected. A few of you might remember this post, from last year. I fabricated the extender after I cleaned the filters last year, so I didn't get to test it out until today! It worked really well, and made this back-breaking chore much less back-breaking.

As I've mentioned before, I'm not going to let my CH-rise year after year, and only fix it after it becomes unmanageable, by draining half my pool. Instead, I'll drain just a few inches once a year, every year, to keep my CH more stable and to keep from having to empty my pool more than I need to. Stay tuned for tomorrow's installment of "Oh Geez, What Did Dirk Do This Time!?"

Great lessons learned for all of us.
I wish Pentair would make an extender with a valve shut off for the drain hole. It is very difficult to reach as you pointed out. I do not have a drain nearby as it just flows into the rock covered area.

Confer steps for in-ground pool?

H
Hey y'all, we just bought a house with a pool about a month ago. It's an old 80's pool (timber frame, just dirt under the liner, coping can't be replaced...) and only has 2 ladders.

We're essentially hoping to get as much use out of the pool as we can, and in a few years figure out if we can afford to put a new pool in or fill it in.

I know the Confer stairs are popular for above ground pools, but wondering if anyone has them for their in-ground and can share their experience? They have one model specifically for in ground.

2.) when replacing, I want to use a Hayward product and get the next size up (equivalent of a T-15). I can get one fairly quickly on amazon. Is there a big difference between the W3T models and the 940S models ? It looks like the W3T models are the majority of what I can find online. The 940S is described as the "extended life" cell but not sure that this completely matters. Any thoughts on this ?
