Pwede ba directly i-swap ang water pump to an inverter pump? Need pa ba ng pressure tank if naka inverter na?

You mean pump inverter, sir? Yes, you'll need a pressure tank.

Just as I thought. Sabi kasi ng tubero ko no need for a pressure tank. Sabi ko e di pag nag brownout while naliligo ako, hindi ako makapag banlaw.

So pwede ba direct swap ang water pump to an inverter type? Need ba palitan yung pressure switch?

Consult your supplier on specs of your choice. Some like Grunfos got models that come complete, others just separate the inverter/pressure components from the variable frequency motor.

From the Grundfos site, wala ng pressure tank after the pump, direct to home pipings na.

And available kaya yang Grundfos inverter dito?

See that gray thing on top? That's an 8L pressure tank on the Grundfos CMBE. The brand is distributed locally.

our folks used to have that type of xx liter tank.
it irritated me, because everytime someone washed his hands, the electric pump would run. it wasn't obnoxiously noisy, but i could hear it, nontheless.
and eveerytime there was poweer outage, thee entiree house had no water.
i imagine, one reason folks would settle for this, is because they had no space for the much bigger pressure tank.

i think, a local brand offers/used to offer something very similar.
adjacent to the generic electric pump, was a small pressure tank 1 foot wide x 1 or 2 feet tall.

with out current "full-size" pressure tank system, we still had running water even if there was brownout or the nawasa dried up... until the tank pressure equalized, that is.

Stainless? Come replacement time, go Wellmate, doc. Pressure will be stable longer. No more periodic draining. No risks of bursting at the seams/welds.

yespo. stainless.
the problem nga, is the gradual decrease in the air bubble.
the air bubble gradually decreases, because air under pressure slowly dissolves into the water below it.

so this wellmate has an air bladder instead of air in direct contact with the water?
kinda like the airplane fuel tanks of WW2.
i wonder... how much locally?

addendum.
i googled for price...
yikes!!!
stinless na lang!
heh heh.

So many variables to determine the proper Wellmate(or similar) size, doc. The pump output/size, runtime, cut in/out pressures set. Avoid relatively comparing your existing stainless tank capacity vs bladder tank's 1:1. With proper computation, you might not need 1 as big as what you have. The yikes might just turn yay.[emoji4]
Below is a sample computation of figuring the ideal size.

Just discovered that wall in our room on the ground floor has paint coming off and moisture on some parts. I know the best way to address this is to find and seal all crevices outside which unfortunately is covered by the neighbors wall.

Was planning to paint it with waterproofing paint. Is there a better way? Or is there a superior product you know of which I should use?

So now we know why the room is always moldy.

Here are the pictures pala..

Check out Boysen aquaseal bro. Scrape off the affected part and then apply. Baka may seepage from neighbor's wall kaya nag ddamp yung wall mo. May problema din ako samin ng flaking wall sa loob pag nababasa yung exterior wall.

if the water is seeping in from the other side of your wall,
you will have to do something on the outside, to prevent the water from seeping into your concrete wall. painting it on the inside will only work for a short time.
it is also possible, that your neighbor has the same problem with his wall.
if so, you should join forces. install a cover between your two walls, to divert rain from both your wall exteriors so that rain water won't be able to fall in and seep thru both your walls.

Agree with you Doc, probably they are firewall to firewall. They need to put a capping on top of the exterior wall to prevent water seepage.

Thanks, na solve ba ng Aquaseal?

Edit: pang bare substrate lang pala ito

I saw this rain or shine hydrolock, unfortunately wala ata silang website kaya I cannot find any info on the preparation required. Don't even know if it can be painted over paint. Anyone familiar with this?

[viper888]

I'd check the flashing between the the two firewalls in the roof since that is the source of the leak. The rain or shine hydrolock should work since the leak is negative pressure.

Instructions for paint are usually printed on the bucket. You will most likely have to peel off the existing paint

[papi smith]

Thanks, I watched 2 yt vids on this and they both recommend stripping the old paint. One was recommending his products (buildrite) while the other was just trying to share and says that any cementitious paint will do the trick.

But they both agreed that this is a solution for situations like mine where houses are built side by side therefore difficult to address externally. And they mentioned ideal for basement, which means this is really effective if done correctly.
