It should be fine. This mod has the features (albet much simpler) of Pump Extender so as long as you only use that feature from one of the mods it should be fine I think.

Is it compatible with Pump Extender?

I am looking for a mod which increases the output of bad water pumps, because building large with IronTeeth gets you in problems because of their huge amount of bad water they need.

Does it stop pumping more after 0.5m³? Do you have more water than that? Note that the pump itself can only pump water on the one block the pipe is on. Normally in the game it doesn't really matter because water then will immediately level itself from the surrounding blocks but if it's too fast, maybe you take up all the water in the current block and surrounding water doesn't go in fast enough?

any way to have it also increase the amount of water that the mechanical pump puts into the other side as far as CMS. cant figure out how to get more than .5 cms out no matter what i change.

Not sure what you mean by "individual pump". If you mean you want to choose how long for each kind of pump then you will need Extended Pump. This mod only lets you choose a multiplier or a fixed maximum depth for all kinds of pumps (so if it was 2, it is now 4 or a fixed 10 for example)

So with this mod, we can essentially make the pumps as long as we need them for each individual pump?

working now, thanks!!

v7.1.0: removed Water production multiplier and add Water production time multiplier instead due to the other option being too unstable and causes crashes.

Thanks for reporting the issue! I think the game didn't expect Water to be produced/used by more than 1 at a time. Please tell me if the new option causes any issue.

Oops that doesn't sound right... I have encountered that one before but I thought it's due to one of my storage mod while in Dev mode. So turned out the Production Multiplier does something funny... For now please turn it to 1x just to be safe. I will check that one again when I have time. I added that option just to be 'enough', I didn't play much with that option changed because it's too OP :P maybe I should reduce the work time instead of increasing the production.

i wish i could screen shot..first i tried multipliers but kept getting the argumentexception. then i tried i set the product conversion rate to .1 and it spiked my storage up to 19M water, rather than affecting the production of the pumps. i think something isn't connecting right.

when i've upped the multiplier to anything above 1, i'm getting "ArgumentException: Can't take 5x Water. There's not enough unreserved." - what's going on with that error?

Wow you're on fire!
These mods you create take care of some really annoying things in game, in this case correcting the issue of water pumps with a ridiculously short length.
It looks like while I'm thinking about "hmmm I'd like to change this into that ..." 5 minutes later walah it's in the workshop hahah
